Objective To summarize the visual outcome of patients with severe ocular trauma treated with vitreous surgery. Methods Clinical data of 188(191 eyes) with severe ocular trauma treated with vitreous surgery in a period from November 1996 to April 1998 were analysed retrospectively. Results The study included penetrating injury in 56 eyes, foreign bodies in the posterior segment in 70 eyes, blunt injury in 41 eyes , and globe rupture in 24 eyes. Main complications included endophthalmitis in 35 eyes, choroidal bleeding in 20 eyes, retinal detachment in 60 eyes, and vitreous hemorrhage in 97 eyes. Post-opera-tively, out of 188 eyes, except for 3 of patients too young to examine, visual acuity improved in 133(70.7%), including 85(45.2%) with visal acuity 0.02-1.0, 46(24.5%) remained unchanged; and 9(4.8%) had worse vision. Among 34 with no-light-perception, 12 had light-perception or over. Conclusion A majority of severe trauma eyes can be salvaged with considerable visual recovery after adequate and timely vitreous surgery. (Chin J Ocul Fundus Dis,1999,15:4-6)
ObjectiveTo observe the optical coherence tomography angiography (OCTA) image characteristics of polypoid choroidal vascular disease (PCV) after intravitreal injection of anti-vascular endothelial growth factor drugs, and to discuss its significance in the diagnosis and follow-up of PCV.MethodsA retrospective case study. From August 2018 to January 2020, 22 eyes of 22 patients with PCV diagnosed in the ophthalmological examination of Affiliated Hospital of Weifang Medical University were included in the study. Among them, there were 10 males with 10 eyes and 12 females with 12 eyes; the average age was 67.75±9.53 years. Best corrected visual acuity (BCVA), OCTA, and indocyanine green angiography (ICGA) were performed. All the affected eyes were injected vitreously with 10 mg/ml Conbercept 0.05 ml (including Conbercept 0.5 mg) once a month for 3 consecutive months.Tthe macular area of 3 mm×3 mm and 6 mm×6 mm with an OCTA instrument was scanned, and the foveal retinal thickness (CRT) was measured, the area of abnormal branch blood vessels (BVN). pigment epithelial detachment before and 12 months after treatment (PED) height, foveal choroid thickness (SFCT) were performed. The diagnosis rate of PCV by OCTA was observed, as well as the changes of various indicators of BCVA and OCTA. Before and after treatment, BCVA and CRT were compared by paired t test; BVN area, PED height, and SFCT were compared by variance analysis. The changes in imaging characteristics of OCTA before and after treatment were analyzed.ResultsAmong the 22 eyes, 8 eyes were BVN; 5 eyes were polypoid lesions (polyps); 5 eyes were BVN combined with polyps; 3 eyes were not found with BVN and polyps; 1 eye with small vascular network structure, this eye was ICGA Appears as strong nodular fluorescence (polyps). The detection rate of PCV by OCTA was 86.36% (19/22). Twelve months after treatment, BVN was significantly reduced or disappeared in 16 eyes (72.72%, 16/22); polyps disappeared in 17 eyes (77.27%, 17/22). Compared with before treatment, 12 months after treatment, BCVA increased (t=3.071), CRT decreased (t=2.440), the difference was statistically significant (P＜0.05); the average BVN area, PED height, and SFCT decreased. The difference in average BVN area and PED height was statistically significant (F=2.805, 3.916; P＜0.05), and the difference in SFCT was not statistically significant (F=0.047, P＞0.05).ConclusionsThe detection rate of PCV by OCTA is 86.36%. After PCV anti-vascular endothelial growth factor drug treatment, BVN area decrease and polyps subside. OCTA is an effective means for PCV diagnosis and follow-up after anti-VEGF drug treatment.
Purpose To evaluate the safety and efficacy of draining subretinal fluid with transchoroidal probing by using the traditional needling and diode endolaser probing. Methods The investigation included 70 consecutive patients(74 eyes) with rhegmatogenous retinal detachment undergoing scleral buckling surgery.Seventy cases were randomly divided into 2 groups,group A 34 cases(36 eyes)with the needle drainage procedure and group B 36 cases(38 eyes) with the diode probe respectively.The safety and efficacy were compared in between the 2 groups. Results No operative failure was found in these 2 groups.In group A,subretinal hemorrhage occurred in 3 eyes,and retinal incarceration,retinal preforation in one eye. No significant complication occurred in group B. Conclusion Diode laser drainage has the advantage in that it may reduce the incidence of operative complication with drainage.This technique might be used in any case requiring drainage of subretinal fluid especially of rhegmat ogenous retinal detachment in cases of shallow retinal detachment.

Peripheral exudative hemorrhagic chorioretinopathy (PEHCR) is a peripheral retinal disease characterized by subretinal hemorrhage and/or subretinal pigment epithelial hemorrhage or exudation. It is often misdiagnosed as age-related macular degeneration, polypoidal chorioretinopathy or choroidal melanoma. With the development of multimodal imaging, PEHCR has different features under different examinations, such as B-scan ultrasound, fluorescein fundus angiography, optical coherence tomography and so on, which contributes to differention from other diseases. Clinical treatments for the disease include intravitreal injection of retinal photocoagulation therapy, anti-vascular endothelial growth factor, pars plana vitrectomyand so on, but there is still no universal consensus. In order to gain a deeper understanding of the clinical features, treatment options and prognosis of PEHCR, minimize missed diagnoses and misdiagnoses, and improve treatment efficiency, further research is required.
Wet age-related macular degeneration (wAMD) is caused by choroidal neovascularization (CNV), which occurs when the choroidal new capillaries reach the RPE layer and photoreceptor cell layer through the ruptured Bruch membrane, leading to neovascularization bleeding, leakage, and scarring. In view of the important role of VEGF in the development of CNV, targeted therapy with various intraocular anti-VEGF drugs is the first-line treatment for wAMD. However, the efficacy of anti-VEGF drugs in the treatment of wAMD is affected by a variety of factors, and some patients still have problems such as unresponsiveness, drug resistence, tachyphylaxis, long-term repeated injections, and severe adverse effects. It is the direction of future researches to deeply explore the physiological and pathological process of wAMD, find the cause of CNV formation, and seek better therapies.
