PURPOSE To analyze differences in ultra-widefield fluorescein angiography (UWFFA) findings between patients with recurrent postvitrectomy diabetic vitreous hemorrhage (PVDVH) and patients with non-PVDVH (NPVDVH). METHODS Patients were categorized as PVDVH when vitreous hemorrhage recurred after diabetic vitrectomy. Age-matched control diabetic patients in whom vitreous hemorrhage did not recu...

Background: To investigate the effects of drainage of premacular subhyaloid hemorrhage into the vitreous with Nd:YAG laser in 13 eyes of 12 patients with 3 months follow-up. Method: The study was conducted between January 2001 and December 2001. Thirteen eyes of 12 patients had a circumscribed premacular hemorrhage and were treated with Nd:YAG laser to drain the blood into the vitreous cavity. ...

BACKGROUND To investigate the reasons for postvitrectomy diabetic vitreous hemorrhage (PDVH), and to analyze the time of PDVH onset, the treatment of PDVH, the visual outcome of the treatment, and factors that affect visual acuity after treatment. MATERIALS AND METHODS Overall, 292 eyes from 236 patients with proliferative diabetic retinopathy (PDR) underwent vitrectomy from 2006 to 2010. Fif...

BACKGROUND We classified iatrogenic retinal break formation during 20-gauge pars plana vitrectomy for proliferative diabetic retinopathy into three types according to the mechanism of development, and evaluated the association of each type with postoperative complications. This is the largest series of such patients published to date. METHODS This was a retrospective comparative study of 760 ...

PURPOSE Previous studies from this laboratory revealed that vitreous insulin-like growth factor biological activity increases in diabetes and that this change can precede the onset of proliferative diabetic retinopathy. The goal of this study was to characterize this phenomenon in an animal model of alloxan-induced diabetes. METHODS Swine made diabetic with intravenous alloxan were euthanized...

purpose : to review the effectiveness and safety of perioperative injection of bevacizumab in vitrectomy for proliferative diabetic retinopathy (pdr) methods : a literature search of all english articles from the medline and scopus databases was performed. original articles, case reports and letters were included. results : nineteen, 3 and 5 studies reported preoperative, intraoperative and pos...

purpose: to evaluate the success rate of nd:yag laser membranotomy in patients with diabetic premacular hemorrhage. methods: this interventional case series included 24 eyes of 22 patients referred to retina clinic of farabi eye hospital, tehran, iran during 2000-2007 with chief complaint of sudden loss of vision and clinical diagnosis of premacular hemorrhage due to proliferative diabetic reti...

This study aims to evaluate the safety and efficacy of intravitreal bevacizumab (IVB) at the end of vitrectomy in prevention of rebleeding in patients with diabetic vitreous hemorrhage. Methods: This is a retrospective interventional study comprised of 30 eyes from 30 patients who underwent 23 G pars plana vitrectomy for diabetic vitreous hemorrhage (VH). IVB (1.25 mg/0.05 ml) was injected at t...

To evaluate the prevalence and risk factors of neovascular glaucoma (NVG) after vitrectomy in patients with vitreous hemorrhage associated with proliferative diabetic retinopathy (PDR). This retrospective, noncomparative, observational study included 127 eyes of 127 patients with PDR who received vitrectomy with a follow-up period of at least 6 months. The prevalence of NVG and associated risk ...
