However, few studies have comprehensively investigated the clinical features of different eye injury types or possible risk factors for poor prognosis.Methods: We retrospectively reviewed all consecutive records of explosive eye injuries(1449 eyes in 1115 inpatients)in 14 tertiary referral hospitals in China over 12 years(between January 1, 2008 and December 31, 2019). Data on demographics, eye injury types, ocular findings, treatments, and factors affecting visual prognosis were extracted from a standardized database of eye injuries and statistically analyzed.Results: Mechanical ocular trauma accounted for 94.00% of explosion-related eye injuries, among which intraocular foreign bodies(IOFBs) resulted in 55.17% of open globe injuries(OGIs) and contusion caused 60.22% of close globe injuries(CGIs). Proliferative vitreous retinopathy(PVR) was more common in perforating(47.06%) and IOFB(26.84%)than in penetrating(8.79%) injuries, and more common with laceration(24.25%) than rupture(9.22%, P<0.01).However, no difference was observed between rupture and contusion. Ultimately, 9.59% of eyes were removed and the final vision was ≤4/200 in 45.82% of patients. Poor presenting vision [odds ratio(OR)=5.789], full-thickness laceration of the eyeball ≥5 mm(OR=3.665), vitreous hemorrhage(OR=3.474), IOFB(OR=3.510), non-mechanical eye injury(NMEI, OR=2.622), rupture(OR=2.362), traumatic optic neuropathy(OR=2.102), retinal detachment(RD,OR=2.033), endophthalmitis(OR=3.281), contusion(OR=1.679), ciliary body detachment(OR=6.592), zone Ⅲ OGI(OR=1.940), and PVR(OR=1.615) were significant negative predictors for poor visual outcomes(P<0.05).Conclusions: Explosion ocular trauma has complex mechanisms, with multiple eyes involved and poor prognosis. In lethal level Ⅰ explosion injuries, eyeball rupture is a serious condition, whereas contusion is more likely to improve. In level Ⅱ injuries, IOFBs are more harmful than penetrating injuries, and level Ⅳ represents burn-related eye injuries.PVR is more associated with penetrating mechanisms than with OGI. Identifying the risk predictors for visual prognosis can guide clinicians in the evaluation and treatment of ocular blast injuries.展开更多

Patient-related factors(demographic features, systemic and ocular comorbidities) and management-related factors(surgical duration, type of surgery, type of lens) were analysed for their association with visual outcome(acuity). RESULTS: Most patients were Malays(48.23%) and Chinese(38.55%) aged 60-79y(range 0-100y). Hypertension(58.61%) and diabetes(44.89%) were major systemic comorbidities. Glaucoma(6.71%) and diabetic retinopathy(10.12%) were the main ocular comorbidities. Other comorbidities were age-related macular degeneration, pterygium, corneal opacities, macula diseases, vitreous haemorrhage, retinal detachment and pseudoexfoliation(0.70%-1.60%). Preoperatively 7150(55.03%) eyes presented with poor vision. Uncomplicated phacoemulsification performed quickly with foldable lenses gave good results. CONCLUSION: Primary care physicians should initiate early detection to prevent late presentation of cataracts causing poor vision and should discuss the risks and benefits of cataract surgery while emphasizing the role of pre-existing comorbidities which may affect the visual outcomes. For good results, phacoemulsification should be done within 30 min, without complications, using foldable posterior chamber intraocular lens.展开更多

Best corrected visual acuity(BCVA) values were recorded using standard Snellen acuity chart and were converted to logarithm of the minimum angle of resolution(log MAR) scale for statistical analysis. The visual outcome was defined by the final BCVA(excellent visual outcome: final BCVA of 20/40 or better;poor visual outcome: final BCVA less than 20/200). Statistical analysis of collected data was performed using IBM SPSS Statistics version 23. A 2-tailed P value of less than 0.05 was considered statistically significant throughout the study. RESULTS: The average age ranged from 1 to 79 years old(mean age, 34.8±12.7 SD) and the majority of patients were men(626, 93.6%). The major cause of ocular injury was hammering(383, 57.2%). Almost all the patients(97.8%) underwent surgeries(97.8%) and the average time interval between injury and surgery was 26.4±322.3 d(0-7300), while 327 patients received surgeries within 24 h(48.9%) and 590 patients received surgeries within seven days(88.2%) after IOFBs injury. The poor BCVA was associated with older age(P=0.013), larger IOFBs size(P<0.001), presence of complications(P<0.001) and worse presenting BCVA(P<0.001). On the contrary, younger age(P=0.005), smaller IOFBs size(P<0.001), absence of complications(P<0.001) and better presenting BCVA(P<0.001) were considered to relate to excellent BCVA.CONCLUSION: Multiple prognostic factors may influence the final visual outcome, including age, size of IOFBs, complications and presenting BCVA. Meanwhile, further education and promotion on eye protection should be taken for the improvement on self-protection and selfhealth awareness.展开更多

Visual outcome is unpredictable because this is not determined solely by the lens. There is a lack of a standard classification, investigations, and treatment guidelines related to the outcome, with considerable debate regarding predictive models. We review the predictors of visual outcome following surgical treatment of traumatic cataracts, which may act as a guide to clinicians.展开更多

Totally 412 patients undergoing cataract surgery with either the CPS using the 30-degree balanced? tip(n=207) or the IPS using the 30-degree Kelman? tip(n=205). Intraoperative and postoperative outcomes were documented prospectively up to one month follow-up. Nuclear sclerosis(NS) grade, cumulated dissipated energy(CDE), preoperative corrected distance visual acuity(CDVA), and CDVA at one month were recorded. RESULTS: CDE was 13.50% less in the whole CPS compared with the whole IPS subcohort. In eyes with NS grade III or greater, CDE was 28.87% less with CPS(n=70) compared with IPS(n=44)(P=0.010). Surgical complications were not statistically different between the two subcohorts(P=0.083), but in the one case of vitreous loss using the CPS, CDVA of 6/4 was achieved at one month. The mean CDVAs(VOs) at one month for NS grade III and above cataracts were-0.17 log MAR(6/4.5) in the CPS and-0.15 log MAR(6/4.5) in the IPS subcohort respectively(P=0.033).CONCLUSION: CDE is 28.87% less, and VOs are significantly improved, in denser cataracts in the CPS compared with the IPS. The authors recommend the CPS for cases with denser nuclei.展开更多

The Ocular Trauma Score was measured. The minimum follow-up from presentation was 6mo.·RESULTS: Ninety patients(77 males, 13 females), with a mean age of 32.7 ±15.8y were included over the 6-month period. The majority of cases occurred in the workplace(47 patients), followed by home(14 patients).The mean visual acuity(log MAR) of patients significantly improved from 2.36 ±0.72 preoperatively to 1.50 ±1.14 postoperatively. Twenty-three patients had preoperative vision better than 2.0 log MAR, the postoperative visual acuity was significantly better among these patients than patients with worse than 2.0 log MAR(P <0.001). Visual improvement between groups with early vitrectomy(<7d)and delayed vitrectomy(>7d) was not significantly different(P =0.66). Postoperative visual acuity was not significantly different between patients with injury in Zone I and II(P =0.64), but patients with injury in Zone III had significantly poorer visual acuity(P =0.02). Patients with relative afferent pupillary defect had significantly poorer postoperative visual acuity(P =0.02). Preoperative visual acuity, the difference of preoperative and postoperative visual acuity, and postoperative visualacuity were significantly different between groups with different ocular trauma scores(P <0.001).·CONCLUSION: Trauma is more likely to occur in men under 40 y of age and in the workplace. The favorable final visual outcome is associated with the absence of afferent pupillary defect, ocular trauma score and presenting visual acuity as well as the zone of injury, and not associated with the timing of vitrectomy.展开更多

The uncorrected distance visual acuity(UDVA), corrected distance visual acuity(CDVA), and manifest refraction were assessed during 1 d, 1 wk, and 1 mo follow-ups. The orientation of the Tecnis Toric IOL was evaluated during 1 wk and 1 mo follow-ups.RESULTS: There were no significant differences in UDCA or CDVA between two groups at 1 mo postoperatively, though relatively more subjects had UDVA values of 20/25 or better in Femto phaco group than in the Conventional group(P>0.05). A lower but not significantly lower rate of having more than 5° of IOL rotation was observed in Femto phaco group at the 1-month follow-up, while a significant lower rate of residual astigmatism of ≤1 D was observed in Femto phaco group.CONCLUSION: The Femto phaco group has significantly more subjects with the residual astigmatism of ≤1 D, but there are no significant differences in rotation stability and visual outcomes as compared with the Conventional phaco group after the application of the Tecnis toric IOL in this cohort.展开更多

Method: Prospective study including 150 patients with implantation of three IOLs: trifocal diffractive IOL AT LISA tri 839 MP (ATLISA, n = 50), trifocal diffractive IOL PhysIOL FineVision (FineVision, n = 50) and the extended range of vision IOL Tecnis Symfony ZRX00 (Symfony, n = 50). Patients were followed up for 6 months after surgery. Major parameters were monocular and binocular uncorrected (UDVA) and corrected (CDVA) distance, uncorrected (UIVA) and distance corrected (DCIVA) intermediate (80 cm), and uncorrected (UNVA) and distance corrected (DCNVA) near (40 cm) visual acuities (UNVA), contrast sensitivity (CS), defocus curve as well as patient satisfaction and spectacle use. Results: Mean postoperative decimal UDVA was 1.01 for Symfony, 0.96 for ATLISA and 0.95 for the FineVision IOL. Postoperative UIVA was 0.95 with Symfony, 0.72 with ATLISA and 0.85 with the FineVision IOL. Postoperative UNVA was 0.96 with the FineVision, 0.72 with the ATLISA and 0.63 with the Symfony IOL. The Symfony defocus curve showed the smoothest profile. Mean mesopic CS was 0.84 log units with the Symfony, 0.83 with the ATLISA (0.83) and 0.65 with the FineVision IOL. Mean photopic CS with the Symfony, ATLISA and FineVision was 1.05, 0.85 and 0.69 log units, respectively. Twenty percent of the patients with the ATLISA and FineVision IOLs and 5.6% of the Symfony patients reported halos and glare as troublesome or disabling. Reading glasses were frequently used by 5.6% of the Symfony patients. All patients with the trifocal IOLs reported to be spectacle-free for any distance. Conclusion: All 3 IOLs produce excellent results with high levels of spectacle independence. The Symfony produces better levels of distance and intermediate visual acuity, whereas the trifocal IOLs produced better near vision. Higher frequency of dysphotopsia was seen with the trifocal IOLs.展开更多

In the developed world, trauma is also the leading cause of unilateral blindness and is preceded only by the cataract as a cause for vision impairment. Males are much more likely than females to sustain ocular trauma. The ocular effects of trauma can be far-reaching, so timely intervention is of prime importance to improve the visual outcome. General Objective: To evaluate the visual outcome after ocular injury. Methods: This study was conducted at Nagri Eye Hospital, Ahmadabad. In total, 68 eyes of 68 patients with eye injury were included in this study. Detail history was taken from the entire patient and a detailed ocular examination was done. Results: The mean age of incidence of the patients was 25.39 ± 16.89. The commonest age group presented with ocular trauma was i.e., 11 - 20 yrs. A great majority of patients were male with the mean age of 25.89 ± 16.55 accounting for 83.82%. The majority of the patients have visited the hospital in between the time period of 24 hrs - 1 wk (57.35%), followed by 23.52% within the time period of p-value Conclusions: The majority of cases were youth males with the age group of 25 yrs. All the cases with ocular trauma were unilateral. The trauma was common in industrial workers with the majority of the cases of blunt type. There was satisfactory visual improvement in patients who followed-up well.展开更多

文摘Background: Explosions can produce blast waves, high-speed medium, thermal radiation, and chemical spatter,leading to complex and compound eye injuries. However, few studies have comprehensively investigated the clinical features of different eye injury types or possible risk factors for poor prognosis.Methods: We retrospectively reviewed all consecutive records of explosive eye injuries(1449 eyes in 1115 inpatients)in 14 tertiary referral hospitals in China over 12 years(between January 1, 2008 and December 31, 2019). Data on demographics, eye injury types, ocular findings, treatments, and factors affecting visual prognosis were extracted from a standardized database of eye injuries and statistically analyzed.Results: Mechanical ocular trauma accounted for 94.00% of explosion-related eye injuries, among which intraocular foreign bodies(IOFBs) resulted in 55.17% of open globe injuries(OGIs) and contusion caused 60.22% of close globe injuries(CGIs). Proliferative vitreous retinopathy(PVR) was more common in perforating(47.06%) and IOFB(26.84%)than in penetrating(8.79%) injuries, and more common with laceration(24.25%) than rupture(9.22%, P<0.01).However, no difference was observed between rupture and contusion. Ultimately, 9.59% of eyes were removed and the final vision was ≤4/200 in 45.82% of patients. Poor presenting vision [odds ratio(OR)=5.789], full-thickness laceration of the eyeball ≥5 mm(OR=3.665), vitreous hemorrhage(OR=3.474), IOFB(OR=3.510), non-mechanical eye injury(NMEI, OR=2.622), rupture(OR=2.362), traumatic optic neuropathy(OR=2.102), retinal detachment(RD,OR=2.033), endophthalmitis(OR=3.281), contusion(OR=1.679), ciliary body detachment(OR=6.592), zone Ⅲ OGI(OR=1.940), and PVR(OR=1.615) were significant negative predictors for poor visual outcomes(P<0.05).Conclusions: Explosion ocular trauma has complex mechanisms, with multiple eyes involved and poor prognosis. In lethal level Ⅰ explosion injuries, eyeball rupture is a serious condition, whereas contusion is more likely to improve. In level Ⅱ injuries, IOFBs are more harmful than penetrating injuries, and level Ⅳ represents burn-related eye injuries.PVR is more associated with penetrating mechanisms than with OGI. Identifying the risk predictors for visual prognosis can guide clinicians in the evaluation and treatment of ocular blast injuries.
文摘AIM: To explore the associations between various characteristics of Malaysian cataract patients and their management, and their post-operative visual outcomes, to inform relevant bodies to reduce cataract-related blindness.METHODS: We conducted a descriptive secondary data analysis of cataract surgery patients in Melaka Hospital, from 2007 to 2014 using the National Eye Database(NED). Patient-related factors(demographic features, systemic and ocular comorbidities) and management-related factors(surgical duration, type of surgery, type of lens) were analysed for their association with visual outcome(acuity). RESULTS: Most patients were Malays(48.23%) and Chinese(38.55%) aged 60-79y(range 0-100y). Hypertension(58.61%) and diabetes(44.89%) were major systemic comorbidities. Glaucoma(6.71%) and diabetic retinopathy(10.12%) were the main ocular comorbidities. Other comorbidities were age-related macular degeneration, pterygium, corneal opacities, macula diseases, vitreous haemorrhage, retinal detachment and pseudoexfoliation(0.70%-1.60%). Preoperatively 7150(55.03%) eyes presented with poor vision. Uncomplicated phacoemulsification performed quickly with foldable lenses gave good results. CONCLUSION: Primary care physicians should initiate early detection to prevent late presentation of cataracts causing poor vision and should discuss the risks and benefits of cataract surgery while emphasizing the role of pre-existing comorbidities which may affect the visual outcomes. For good results, phacoemulsification should be done within 30 min, without complications, using foldable posterior chamber intraocular lens.
文摘AIM: To describe the clinical characteristics and analyze prognostic factors that influence visual outcome in 669 patients with intraocular foreign bodies(IOFBs).METHODS: Medical records of 669 patients with IOFBs from West China Hospital were reviewed. Best corrected visual acuity(BCVA) values were recorded using standard Snellen acuity chart and were converted to logarithm of the minimum angle of resolution(log MAR) scale for statistical analysis. The visual outcome was defined by the final BCVA(excellent visual outcome: final BCVA of 20/40 or better;poor visual outcome: final BCVA less than 20/200). Statistical analysis of collected data was performed using IBM SPSS Statistics version 23. A 2-tailed P value of less than 0.05 was considered statistically significant throughout the study. RESULTS: The average age ranged from 1 to 79 years old(mean age, 34.8±12.7 SD) and the majority of patients were men(626, 93.6%). The major cause of ocular injury was hammering(383, 57.2%). Almost all the patients(97.8%) underwent surgeries(97.8%) and the average time interval between injury and surgery was 26.4±322.3 d(0-7300), while 327 patients received surgeries within 24 h(48.9%) and 590 patients received surgeries within seven days(88.2%) after IOFBs injury. The poor BCVA was associated with older age(P=0.013), larger IOFBs size(P<0.001), presence of complications(P<0.001) and worse presenting BCVA(P<0.001). On the contrary, younger age(P=0.005), smaller IOFBs size(P<0.001), absence of complications(P<0.001) and better presenting BCVA(P<0.001) were considered to relate to excellent BCVA.CONCLUSION: Multiple prognostic factors may influence the final visual outcome, including age, size of IOFBs, complications and presenting BCVA. Meanwhile, further education and promotion on eye protection should be taken for the improvement on self-protection and selfhealth awareness.

文摘AIM:To compare the visual outcomes of children with small(≤3 mm)posterior polar cataracts(PPC)and posterior lenticonus who had cataract extraction surgery with the visual outcomes of those who were managed conservatively.METHODS:Children who initially had small PPC and posterior lenticonus who were followed up over 1-year period were retrospective reviewed in the study.Patients receiving surgery were compared with those receiving conservative therapy.The axial length,keratometry,refraction,bestcorrected visual acuity(BCVA),and strabismus measurements were recorded.Lens morphology,i.e.,the location,size,and depth of the cataract lesion,was measured with a Scheimpflug imaging system.To help control for baseline differences in the groups,patients were matched with controls by propensity score methodology.RESULTS:The study evaluated 60 patients(30 in the surgery group and 30 in the conservative therapy group)after matching by propensity score.Patients who underwent cataract surgery showed greater BCVA improvements(0.36±0.24 logMAR)than patients who were treated without surgery(0.22±0.26 logMAR;P=0.036).Surgery was effective in patients with a rear projection length(RPL)less than 1.0 mm and a pretreatment BCVA worse than 0.52 logMAR.CONCLUSION:Children with small PPC and posterior lenticonus who undergo cataract surgery experience greater BCVA improvements than those managed conservatively.Certain patients presenting with a RPL less than 1.0 mm and a pretreatment BCVA of 0.52 logMAR or worse may benefit from surgery.
文摘Dear Editor,We’re interested in the article by Mo and colleagues~[1] about"Evaluation of hyperreflective foci as a prognostic factor of visual outcome in retinal vein occlusion".They performed a multiple linear regression analysis with backward elimination to analyse the association of best corrected visual acuity(BCVA)with the numbers of hyperreflective foci(HF)in different layers.In addition,they summarized the results of multivariate regression analyses in Table 3~[1].
文摘Optical coherence tomography(OCT)is a technology that is widely used to assess structural abnormalities in the retina for a variety of pediatric conditions.The introduction of this instrument has allowed for widespread access to minimally invasive standardized,reproducible quantified structural assessments of the optic nerve and retina.This has had important implications in pediatric optic neuropathies,populations in whom monitoring of disease activity is essential to make treatment decisions.OCT has had particular relevance for inflammatory optic neuropathies,as onset of an inflammatory optic neuropathy may herald the onset of a chronic inflammatory disorder of the central nervous system(CNS)such as multiple sclerosis,neuromyelitis optica spectrum disorder(aquaporin 4 antibody positive),and myelin oligodendrocyte glycoprotein(MOG)associated disorders.This paper will focus on the application of OCT technology to this group of disorders in pediatrics.After reviewing pediatric-specific anatomic and practical issues pertinent to OCT,we will review knowledge related to the use of OCT in inflammatory pediatric optic neuropathies,with a focus on structural outcomes and their correlation with functional outcome metrics.
文摘Traumatic cataract resulting from open- or closed-globe ocular trauma is one of the most common causes of blindness. Visual outcome is unpredictable because this is not determined solely by the lens. There is a lack of a standard classification, investigations, and treatment guidelines related to the outcome, with considerable debate regarding predictive models. We review the predictors of visual outcome following surgical treatment of traumatic cataracts, which may act as a guide to clinicians.
文摘AIM: To evaluate surgical outcomes(SOs) and visual outcomes(VOs) in cataract surgery comparing the Centurion? phacoemulsification system(CPS) with the Infiniti? phacoemulsification system(IPS).METHODS: Prospective, consecutive study in a singlesite private practice. Totally 412 patients undergoing cataract surgery with either the CPS using the 30-degree balanced? tip(n=207) or the IPS using the 30-degree Kelman? tip(n=205). Intraoperative and postoperative outcomes were documented prospectively up to one month follow-up. Nuclear sclerosis(NS) grade, cumulated dissipated energy(CDE), preoperative corrected distance visual acuity(CDVA), and CDVA at one month were recorded. RESULTS: CDE was 13.50% less in the whole CPS compared with the whole IPS subcohort. In eyes with NS grade III or greater, CDE was 28.87% less with CPS(n=70) compared with IPS(n=44)(P=0.010). Surgical complications were not statistically different between the two subcohorts(P=0.083), but in the one case of vitreous loss using the CPS, CDVA of 6/4 was achieved at one month. The mean CDVAs(VOs) at one month for NS grade III and above cataracts were-0.17 log MAR(6/4.5) in the CPS and-0.15 log MAR(6/4.5) in the IPS subcohort respectively(P=0.033).CONCLUSION: CDE is 28.87% less, and VOs are significantly improved, in denser cataracts in the CPS compared with the IPS. The authors recommend the CPS for cases with denser nuclei.
文摘Background:To evaluate the safety,efficacy,refractive outcomes and causes for bilensectomy[phakic intraocular lens(plOL)explantation with cataract surgery and pseudophakic intraocular lens(IOL)implantation]in patients previously implanted with posterior chamber plOLs(PC plOLs).Methods:This multi-center retrospective study included 87 eyes of 55 patients who underwent bilensectomy for PC plOL with a follow-up time of 12 months.The uncorrected and corrected distance visual acuities(UDVA,CDVA),endothelial cell density before and after bilensectomy were assessed,as well as the cause of bilensectomy and intra or postoperative complications.Results:There was a statistically significant improvement in UDVA and CDVA after bilensectomy(P=0.00).The main reason for bilensectomy was cataract development(93.1%of the cases),followed by miscalculation of lens size,and corneal edema.The endothelial cell count remained stable without a statistically significant change after surgery(P=0.67).The refractive efficacy index was 0.8,none of the patients lost lines of CDVA after surgery,73%of the patients were within±1.0D(spherical equivalent)of the target refraction.Intraoperative complications were one posterior capsule rupture with the IOL implanted in the sulcus,and three eyes required the use of pupil expanders for adequate pupil dilation.Postoperatively,one eye developed retinal detachment.The three plOLs models explanted were the implantable collamer lens(ICL);implantable phakic contact lens(IPCL)and the phakic refractive lens(PRL).Conclusions:Good safety and visual outcomes were observed one year after bilensectomy for PC plOLs.There were few intra and postoperative complications and there was no significant endothelial cell loss after the bilensectomy procedure.

文摘Background:To evaluate the safety,efficacy,refractive outcomes and causes for bilensectomy(phakic intraocular lens–pIOL–explantation with cataract surgery and pseudophakic intraocular lens implantation)in patients previously implanted with posterior chamber pIOLs.Methods:This multi-center retrospective study included 87 eyes of 55 patients who underwent bilensectomy for posterior chamber pIOL with a follow up time of 12 months.The uncorrected and best corrected distance visual acuities(UDVA,CDVA),endothelial cell density before and after bilensectomy were assessed,as well as the cause of bilensectomy and intra or postoperative complications.Results:There was a statistically significant improvement in uncorrected and best corrected visual acuities after bilensectomy(p=0.00).The main reason for bilensectomy was cataract development(93.1%of the cases),followed by miscalculation of lens size,and corneal edema.The endothelial cell count remained stable without a statistically significant change after surgery(p=0.67).The refractive efficacy index was 0.8,none of the patients lost lines of CDVA after surgery,73%of the patients were within±1 D(spherical equivalent)of the target refraction.Intraoperative complications were one posterior capsule rupture with the intraocular lens(IOL)implanted in the sulcus,and 3 eyes required the use of pupil expanders for adequate pupil dilation.Postoperatively,one eye developed retinal detachment.The three pIOLs models explanted were the Implantable Collamer Lens(ICL),Implantable Phakic Contact Lens(IPCL)and the Phakic Refractive Lens(PRL).Conclusions:Good safety and visual outcomes were observed 1 year after bilensectomy for posterior chamber phakic intraocular lenses(PC pIOLs).There were few intra and postoperative complications and there was no significant endothelial cell loss after the bilensectomy procedure.
文摘AIM: To evaluate demographic variables and visual outcomes, among patients with ocular injuries involving the posterior segment, managed with pars plana vitrectomy.· METHODS: The records of patients were studied retrospectively from March to September 2010, to determine the age, gender, place of occurrence of trauma, visual acuity, anatomical site, nature of injury,wound length, the presence of an afferent pupillary defect, and the timing of vitrectomy. The Ocular Trauma Score was measured. The minimum follow-up from presentation was 6mo.·RESULTS: Ninety patients(77 males, 13 females), with a mean age of 32.7 ±15.8y were included over the 6-month period. The majority of cases occurred in the workplace(47 patients), followed by home(14 patients).The mean visual acuity(log MAR) of patients significantly improved from 2.36 ±0.72 preoperatively to 1.50 ±1.14 postoperatively. Twenty-three patients had preoperative vision better than 2.0 log MAR, the postoperative visual acuity was significantly better among these patients than patients with worse than 2.0 log MAR(P <0.001). Visual improvement between groups with early vitrectomy(<7d)and delayed vitrectomy(>7d) was not significantly different(P =0.66). Postoperative visual acuity was not significantly different between patients with injury in Zone I and II(P =0.64), but patients with injury in Zone III had significantly poorer visual acuity(P =0.02). Patients with relative afferent pupillary defect had significantly poorer postoperative visual acuity(P =0.02). Preoperative visual acuity, the difference of preoperative and postoperative visual acuity, and postoperative visualacuity were significantly different between groups with different ocular trauma scores(P <0.001).·CONCLUSION: Trauma is more likely to occur in men under 40 y of age and in the workplace. The favorable final visual outcome is associated with the absence of afferent pupillary defect, ocular trauma score and presenting visual acuity as well as the zone of injury, and not associated with the timing of vitrectomy.

文摘AIM: To compare the short-term visual outcomes, residual refractive cylinder, and rotation stability after Tecnis toric intraocular lens(IOL) implantation during femtosecond laserassisted cataract surgery(Femto phaco) and conventional phacoemulsification surgery(Conventional phaco).METHODS: In a prospective cohort study, Conventional phaco and Femto phaco(anterior capsulotomy and lens fragmentation by a femtosecond laser) with Tecnis toric IOL implantation were performed in 40 eyes from 36 patients and 37 eyes from 33 patients, respectively. The uncorrected distance visual acuity(UDVA), corrected distance visual acuity(CDVA), and manifest refraction were assessed during 1 d, 1 wk, and 1 mo follow-ups. The orientation of the Tecnis Toric IOL was evaluated during 1 wk and 1 mo follow-ups.RESULTS: There were no significant differences in UDCA or CDVA between two groups at 1 mo postoperatively, though relatively more subjects had UDVA values of 20/25 or better in Femto phaco group than in the Conventional group(P>0.05). A lower but not significantly lower rate of having more than 5° of IOL rotation was observed in Femto phaco group at the 1-month follow-up, while a significant lower rate of residual astigmatism of ≤1 D was observed in Femto phaco group.CONCLUSION: The Femto phaco group has significantly more subjects with the residual astigmatism of ≤1 D, but there are no significant differences in rotation stability and visual outcomes as compared with the Conventional phaco group after the application of the Tecnis toric IOL in this cohort.
文摘Purpose: To compare the visual and refractive outcomes, patient satisfaction and spectacle independence between three novel designs of diffractive IOLs. Method: Prospective study including 150 patients with implantation of three IOLs: trifocal diffractive IOL AT LISA tri 839 MP (ATLISA, n = 50), trifocal diffractive IOL PhysIOL FineVision (FineVision, n = 50) and the extended range of vision IOL Tecnis Symfony ZRX00 (Symfony, n = 50). Patients were followed up for 6 months after surgery. Major parameters were monocular and binocular uncorrected (UDVA) and corrected (CDVA) distance, uncorrected (UIVA) and distance corrected (DCIVA) intermediate (80 cm), and uncorrected (UNVA) and distance corrected (DCNVA) near (40 cm) visual acuities (UNVA), contrast sensitivity (CS), defocus curve as well as patient satisfaction and spectacle use. Results: Mean postoperative decimal UDVA was 1.01 for Symfony, 0.96 for ATLISA and 0.95 for the FineVision IOL. Postoperative UIVA was 0.95 with Symfony, 0.72 with ATLISA and 0.85 with the FineVision IOL. Postoperative UNVA was 0.96 with the FineVision, 0.72 with the ATLISA and 0.63 with the Symfony IOL. The Symfony defocus curve showed the smoothest profile. Mean mesopic CS was 0.84 log units with the Symfony, 0.83 with the ATLISA (0.83) and 0.65 with the FineVision IOL. Mean photopic CS with the Symfony, ATLISA and FineVision was 1.05, 0.85 and 0.69 log units, respectively. Twenty percent of the patients with the ATLISA and FineVision IOLs and 5.6% of the Symfony patients reported halos and glare as troublesome or disabling. Reading glasses were frequently used by 5.6% of the Symfony patients. All patients with the trifocal IOLs reported to be spectacle-free for any distance. Conclusion: All 3 IOLs produce excellent results with high levels of spectacle independence. The Symfony produces better levels of distance and intermediate visual acuity, whereas the trifocal IOLs produced better near vision. Higher frequency of dysphotopsia was seen with the trifocal IOLs.

文摘Background: As a cause of blindness, ocular injury constitutes 1.5% of all causes of blindness. In the developed world, trauma is also the leading cause of unilateral blindness and is preceded only by the cataract as a cause for vision impairment. Males are much more likely than females to sustain ocular trauma. The ocular effects of trauma can be far-reaching, so timely intervention is of prime importance to improve the visual outcome.
