Purpose: To evaluate the therapeutic effect of combind argon and Nd: YAG laser peripheral iridectomy.Methods: 151 cases (200 eyes) of primary angle-closure glaucoma and combined glaucoma were treated by combined procedure. Argon laser was the first used to create partial iridectomy in 2/3-3/4 thickness without penetrating pigmented epithelium, and then Nd: YAG laser was required to complete a patent iridectomy. Results: A successful iridectomy was achieved in all patients independent of any type of irides (100%). Iris penetration rate in one session presented in 95. 0%. Complications appeared to be less common in our patients: iris bleeding was only seen in 5. 0% cases; the postoperative inflammation was mild; corneal burns, lecalized lenticular opacities and closure of iridectomies were less frequent. The follow-up ranged from 3m to 6. 5 years. The success rate in controling IOP with/ without medications were 99. 0% except 2 eyes failur. No attack occured in 129 eyes with prophylatic laser therapy 展开更多

AIM:To quantitatively assess narrow anterior chamber angle using spectral-domain anterior segment optical coherence tomography(SD-AS-OCT) and ultrasound biomicroscopy(UBM),and to evaluate the correlations and consistency between SD-AS-OCT and UBM.· METHODS:Fifty-five eyes from 40 patients were examined.Patients were diagnosed with primary angleclosure glaucoma(PACG) remission(11 eyes from 8patients),primary angle closure(PAC,20 eyes from 20patients) and PAC suspect(24 eyes from 12 patients).Each eye was examined by SD-AS-OCT and UBM after laser peripheral iridotomy(LPI).The measurements of SD-AS-OCT were angle open distance(AOD),anterior chamber angle(ACA),trabecular iris angle(TIA),and trabecular iris space area(TISA).UBM measurements were AOD and TIA.Correlations of AOD500 and TIA500 between UBM and AS-OCT were assessed.All parameters were analysed by SPSS 16.0 and MedCalc.· RESULTS:ACA,TIA and AOD measured by SD-ASOCT reached a maximum at the temporal quadrant and minimum at the nasal quadrant.Group parameters of AOD500 and AOD750 showed a linear positive correlation,and AOD750 had less variability.UBM outcomes of AOD500 and TIA500 were significantly smaller than those of SD-AS-OCT.The results of the two techniques were correlated at the superior,nasal and inferior quadrants.CONCLUSION:Both UBM and SD-AS-OCT are efficient tools for follow-up during the course of PACG.We recommended using parameters at 750 μm anterior to the sclera spur for the screening and follow-up of PACG and PAC.The two methods might be alternatives to each other. 展开更多

Peripheral nerve injuries are common in clinical practice because of traumas such as crushing and sectioning. Lesions of the nerve structure result in lost or diminished sensitivity and/or motor activity in the innervated territory. The degree of lesion depends on the specific nerve involved, the magnitude and type of pres- sure exerted, and the duration of the compression. The results of such injuries commonly include axonal degeneration and retro- grade degeneration of the corresponding neurons in the spinal medulla, followed by very slow regeneration (Rochkind et al., 2001). The adverse effects on the daily activities of patients with a peripheral nerve injury are a determining factor in establishing the goals of early recovery (Rodriguez et al., 2004). 展开更多

Background Argon laser peripheral iridoplasty (ALPI) is proved to be effective in lowering intraocular pressure (lOP) of patients with mild acute primary angle closure (APAC). It is unclear whether this laser treatment is equally efficient in managing patients with severe APAC. This study aimed peripheral iridotomy (LPI) on patients with refractory APAC, therapy. to evaluate the IOP-lowering efficacy of ALPI and laser who have previously responded poorly to intensive medical Methods Thirty-six patients (8 men and 28 women) were identified as medically refractory APAC, who still had ocular pain, red eye, hazy cornea, closed anterior chamber (AC) angle, and lOP of not less than 21 mmHg after two days or more of anti-glaucoma medication. All enrolled patients underwent ophthalmologic examinations including measurement of visual acuity (VA), best corrected VA (BCVA), lOP, biomicroscopy, and gonioscopy followed by ALPI immediately in the APAC eye and LPI in both eyes. Results All patients were affected unilaterally, with average age of (54.6±11.7) (range, 37.0-75.0) years old. The mean lOP value of the affected eyes dropped from (31.6±7.7) (range, 21.0-39.0) mmHg at enrollment to (18.4±8.7) (range, 10.0-27.0) mmHg 2 hours after ALPI. At follow-up day 7, the mean lOP value maintained at (14.8±4.2) (range, 9.0-21.0) mmHg, which was significantly different (P=0.000) compared with baseline. The average decrease of lOP in the APAC eyes was (16.8±7.4) (range, 12.0-21.0) mmHg. At follow-up three years later, the mean lOP of the APAC eyes stabilized at (16.3±3.2) (range, 9.0-20.0) mmHg with at least 180° of AC angle opened. Conclusion ALPI and LPI lower the lOP of medically refractory cases of APAC though they have responded poorly to anti-glaucoma medication. 展开更多

Background For some high myopic patients with posterior iris bowing, laser periphery iridectomy should be performed pre-operation to prevent pupil block glaucoma if these patients would have phakic intraocular lens implantation to correct high myopia. So we had the opportunity to analysis the influence of laser iridectomy on posterior iris bowing. Methods Eighteen high myopic patients with posterior iris bowing (11 males and 7 females) were involved in the study in Beijing Tongren Eye Center from March 2008 to July 2008. Phakic intraocular lens were implanted to correct their ametropia. The mean age was (32+6) years (range, 25-40 years). The center anterior chamber depth, the pupil diameter, the posterior iris bowing depth and the anterior chamber angle were measured with anterior segment coherence tomography (AS-OCT) under the normal condition, myosis condition induced by 2% pilocarpine, laser periphery iridectomy after myosis, and 2% pilocarpine eluting condition respectively. Results There was no significant difference of center anterior chamber depth under the four conditions (P=0.512). The pupil constricted after pilocarpine (P=0.001). After' laser iridectomy performed and pilocarpine eluted, posterior iris bowing depth reduced more than that in normal condition (P=0.003). The anterior chamber angle reduced significantly after laser periphery iridectomy and pilocarpine eluted (P=0.012). Conclusion Laser periphery iridectomy can reduce the posterior iris bowing, which might be due to the change in aqueous circulate pathway. 展开更多

AIM:To assess the predictive value of baseline parameters of ultrasound biomicroscopy(UBM) for angle widening after prophylactic laser peripheral iridotomy(LPI) in patients with primary angle-closure suspect(PACS).METHODS:Angle-opening distance(AOD),trabecular iris angle(TIA),iris thickness,trabecular-ciliary process angle,and trabecular-ciliary process distance were measured using UBM performed before and two weeks after LPI.Iris convexity(IC),iris insertion,angulation,and ciliary body(CB) size and position were graded.Uni-and multivariate regression analyses were used to determine factors predicting the change in AOD(ΔAOD500,calculated as an angle width change before and after LPI) in all quadrants and in subgroup quadrants based on IC.RESULTS:In 94 eyes of 94 patients with PACS,LPI led to angle widening with increases in AOD500 and TIA(P<0.01).Multivariable regression analysis showed that IC(P<0.001),CB position(P=0.007) and iris insertion(P=0.049) were significantly predictive for ΔAOD500.All quadrants were categorized into extreme IC(27.8%),moderate IC(62.3%),and absent IC(9.9%) subgroups.The AOD500 increased by 220% and no other predictive factor was found in the extreme IC quadrants.The AOD500 increased by 55%,and baseline iris angulation was predictive for smaller changes in ΔAOD500 in the moderate IC quadrants.CONCLUSION:In PACS patients,quadrants with greater iris bowing predict substantial angle widening after LPI.Quadrants with a flatter iris,anteriorly positioned CB,and basal iris insertion are associated with less angle widening after LPI.Quadrants with iris angulation as well as a flatter iris configuration predict a smaller angle change after LPI. 展开更多

AIM:To describe the gonioscopic profile and intraocular pressure(IOP)in primary angle-closure(PAC)disease in patients presenting to a tertiary eye care network in India.METHODS:A cross-sectional hospital-based study that included 31484 new patients presenting between 2011 and 2021.Patients with a clinical diagnosis of PAC/suspect/glaucoma were included.The data was collected from an electronic medical record system.RESULTS:PAC glaucoma(PACG)(47.55%)was the most common diagnosis followed by PAC(39.49%)and PAC suspect(PACS;12.96%).Female preponderance(54.6%)was noted with higher mean age at presentation among males(P<0.0001).PACS and PAC showed the highest prevalence in 6th decade but PACG was higher at 7th decade.The probability of angle opening was 95.93%,90.32%and 63.36%in PACS,PAC and PACG eyes respectively post peripheral iridotomy(PI).Plateau iris syndrome(PIS)was noted in 252 eyes and all showed post dilated rise of IOP.A post dilated IOP rise was also noted with 8.86%,33.95%and 57.19%eyes with PACS,PAC and PACG respectively with IOP rise between 6-8 mm Hg across the disease spectrum.CONCLUSION:The superior quadrant is the narrowest angle and difficult to open with indentation and post PI.The probability of angle opening is less in PIS especially the complete variety along with post dilated IOP rise.The post dilated IOP rise in angle closure eyes warrants a careful dilatation,especially with PIS. 展开更多
