AIM: To investigate the epidemiologic characteristics and outcomes of open globe injury in Shanghai. METHODS: A retrospective study was conducted for 148 unilateral open globe injury cases presenting to a tertiary referral hospital of Shanghai. Electronic medical records were reviewed and phone surveys were conducted to collect and analyze 1) background of patient; 2) setting of injury and clinical signs at presentation; 3) treatment procedure and outcome; 4) quality of life after injury. RESULTS: There were more male patients (77.03%) than females (22.97%), more temporary habitants (79.05%) than residents (20.95%). The subjects in this study presented a significantly lower constitutional status of education than that of the whole Shanghai population (P〈0.001). Occupational injury was the first cause of injuries (39.86%), followed by home accident (20.27%), road accident (16.80%), violent behavior (16.89%) and outdoor injury (6,08%). The 143 subjects (96.62%) were not wearing spectacles at the time of injury. Of all patients, 77 subjects (52.03%) had the outcome of no vision (including enucleation). The classification and regression tree (CART) prognosis presents 59.58% sensitivity to predict visual survival correctly and 80.19% specificity to predict no vision correctly. The patients whose injured eye had no vision reported more reduction of life quality. CONCLUSION: We found that male subject, temporary habitants, low educational status and no eyewear are risk factors of open globe injury in Shanghai. Occupational injury is the leading cause. CART analysis presents a certain agreement to the actual visual outcome. The injury imposes negative impact on quality of life especially in no vision cases. The education of eye protection may help to avoid the injury. 展开更多

AIM: To compare the effects of intravitreal anti-vascular endothelial growth factor(VEGF) and dexamethasone in an experimental rabbit model of posterior penetrating ocular injury.METHODS: Thirty white New Zealand rabbits were included in the study. A posterior penetrating ocular injury was performed at the superotemporal quadrant. They were randomly divided into three groups. The rabbits in group 1 received intravitreal dexamethasone, in group 2 they received intravitreal bevacizumab and those in group 3 received intravitreal physiological saline solution in both eyes. All eyes were examined ophthalmologically on the 1^st, 3^rd, 7^th, 14^th and 28^th days following the injury and the clinical findings were scored. On the day 28, the eyes were enucleated, evaluated and scored macroscopically, histopathologically and scanning electron microscopically.RESULTS: The median clinical score on the 14 th and 28 th days and the median macroscopic score of the dexamethasone group was significantly better than that of control(P=0.004, 0.018). Dexamethasone group was also better than that of bevacizumab group but the differences did not reach statistical significance. Retinal detachment rate was 8.3%, 16.6% and 12.5% in the dexamethasone group, bevacizumab group and control group, respectively(P=0.476). More extensive fibrocelluler proliferations were observed in controls compared with dexamethasone and bevacizumab groups. But these differences did not reach the statistical significance(P=0.538). In scanning electron microscopy all groups showed fibreous stalk and dense collagen fibrils in vitreous. CONCLUSION: This study shows that intravitreal injection of both dexamethasone and bevacizumab may reduce the intraocular fibrous proliferation after an experimental posterior penetrating ocular injury in rabbits. 展开更多

In recent years, people have become increasingly attentive to light pollution influences on their eyes. In the visible spectrum, short-wave blue light with wavelength between 415 nm and 455 nm is closely related to eye light damage. This high energy blue light passes through the cornea and lens to the retina causing diseases such as dry eye, cataract, age-related macular degeneration, even stimulating the brain, inhibiting melatonin secretion, and enhancing adrenocortical hormone production, which will destroy the hormonal balance and directly affect sleep quality. Therefore, the effect of Blu-rays on ocular is becoming an important concern for the future. We describe blue light’s effects on eye tissues, summarize the research on eye injury and its physical prevention and medical treatment. 展开更多

For each patient clinicopathological data was collected which included demographic information,clinical history, primary clinical diagnosis, main cause of ophthalmic surgery(traumatic, non-traumatic), type of surgical procedure(enucleation, evisceration) and pathological report. Patients’ postoperative clinical visits were checked for procedure-related complications during first year after surgery.·RESULTS: One hundred and seven patients(male:65.4%; mean age: 26y) underwent enucleation(n=100) or evisceration(n =7) due to traumatic(n =41) and non-traumatic(n =66) causes. Disfiguring painful blind eye was the most common indication of surgery(66.4%),followed by leukocoria(19.6%) and endophthalmitis(4.7%). The main types of injury included firecracker,traffic and work accidents, and sharp object perforating injury. In 53(80.3%) subjects in non-traumatic group the initial clinical diagnosis matched the histopathologicalresults. Malignant tumors(retinoblastoma: 47.5%,malignant melanoma: 27.3%) were the most common pathological diagnoses followed by phthisis bulbi(25.8%).The most common procedure-related complications were major eye discharge(39.6%), and implant exposure and discharge(20.8%).·CONCLUSION: Trauma and malignant tumors are the leading causes of enucleation-evisceration. Despite developing new techniques and materials, enucleation is still associated with considerable postoperative complications. 展开更多

The promising role of cellular therapies in the preservation and restoration of visual function has prompted intensive efforts to characterize embryonic, adult, and induced pluripotent stem cells for regenerative purposes. Three main approaches to the use of stem cells have been described: sustained drug delivery, immunomodulation, and differentiation into various ocular structures. Studies of the differentiation capacity of all three types of stem cells into epithelial, neural, glial and vascular phenotypes have reached proof-of-concept in culture, but the correction of vision is still in the early developmental stages, and the requirements for effective in vivo implementation are still unclear. We present an overview of some of the preclinical findings on stem-cell rescue and regeneration of the cornea and retina in acute injury and degenerative disorders. 展开更多

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. 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

AIM: To report various ocular lesions caused by accidental instillation of superglue. METHODS: Three cases of ocular injuries are described in children aged 6 years, 3 years and 8 months, following accidental instillation of superglue in the eye. RESULTS: In the first case there was sticking of eyelashes in the medial 1/3 of eyelids in both eyes. In the second case sticking of eye lashes was present in the lateral 1/3 of eyelids in the left eye. In the third case, superglue was present on the right cheek, above the right ear and sticking of eyelids in medial 1/3 in right eye. The eyelids were separated by pulling the lid margins with fingers in the first case and later on superglue was removed by trimming the eyelashes; and by direct trimming the eyelashes in second and third cases. There was no injury to other structures of anterior segment in the first two cases. However, removal of the superglue on the cornea resulted in corneal abrasion in the third case which healed with medical treatment and patching of the right eye. CONCLUSION: Accidental instillation of superglue is possible because of the appearance of the tube like eye ointment tube. Immediate medical aid will prevent ocular morbidity. 展开更多

It measures about 8%-14% of total childhood injuries. This study aims to determine the epidemiological profile of ocular trauma in the pediatric age group attending a tertiary hospital in northern India. Methods: A retrospective study was conducted in our hospital between June 2014 to July 2015 and all the children aged 0-16 years presenting with ocular trauma in eye outpatient department and emergency were enrolled in the study. Various epidemiological parameters like age, sex distribution, duration of presentation, mode of injury, type of injury and final visual outcome were analyzed. Results: Of total 357 patients, 271 (76%) were below the age of 12 years: 41.1% of children with ocular trauma belonged to age group 2-6 years. The male to female ratio was 2.9:1. Out of total patients, 242 (67.8%) presented with closed globe injury. Among the closed globe injury, the history of fall was present in about 35% of children, followed by trauma while playing with bat/ball (15.7%) and finger nail trauma (13.2%). Among open globe injury, trauma with needle, knife, glass and pen were common causes. Home was the most common place of injury (47.8%), followed by streets (17.9%) and playground (14.9%). Conclusion: Children are vulnerable to ocular trauma and need more supervision. Sharp objects like needles, knives, household chemicals like acids should be out of reach of children. 展开更多
