Diabetic retinopathy (DR) is the major cause of acquired blindness in working-age adults. Current treatments for DR (laser photocoagulation, intravitreal corticosteroids, intravitreal antivascular endothelial growth factor (VEGF) agents, and vitreo-retinal surgery) are applicable only at advanced stages of the disease and are associated with significant adverse effects. Therefore, new pharmacol...

OBJECTIVE To evaluate effects of intravitreal ranibizumab on diabetic retinopathy (DR) severity over time in 2 phase 3 clinical trials (RIDE, NCT00473382; RISE, NCT00473330) of ranibizumab for diabetic macular edema. METHODS Participants with diabetic macular edema (n=759) were randomized to monthly sham, 0.3-mg ranibizumab, or 0.5-mg ranibizumab intravitreal injections. Macular laser was ava...

We report a case of peripheral retinal neovascularization and vitreous hemorrhage in the setting of HIV retinopathy that can serve to extend the clinical spectrum of this condition. A 53-year-old African-American woman with AIDS was referred for decreased vision in the left eye and was found to have peripheral retinal neovascularization and vitreous hemorrhage. She had a workup that was negativ...

Aims: To investigate the correlation between the level of angiotensin II and vascular endothelial growth factor (VEGF) in the vitreous fluid and the severity of proliferative diabetic retinopathy (PDR). Methods: During vitreoretinal surgery at the Tokyo Women’s Medical University, vitreous fluid samples were obtained from 51 eyes of diabetic patients with PDR, six eyes of diabetic patients with...

PURPOSE The present study aimed to describe clinical characteristics of patients with posterior vitreous detachment (PVD), to determine the prevalence of retinal tears in PVD patients, and to find predictors for retinal tears in this patient group. METHODS Retrospective analysis of medical records on patients diagnosed with PVD, retinal tears, or vitreous hemorrhage at the Department of Ophth...
