OBJECTIVE To evaluate the efficacy of intraocular gentamicin sulfate and clindamycin in the prevention of acute posttraumatic bacterial endophthalmitis following penetrating eye injuries. METHOD We conducted a multicenter, randomized, double-masked controlled trial of 346 eyes with penetrating eye injury. Following primary repair, eyes were randomized to(More)
INTRODUCTION The insertion/deletion (I/D) polymorphism of the angiotensin-converting enzyme (ACE) gene has been shown to be associated with a number of complications of type 2 diabetes. RESULTS on the development and progression of albuminuria, however, have remained controversial, with ethnic differences being a potential reason.The present study is the(More)
The role of the vascular endothelial growth factor (VEGF) gene polymorphism in proliferative diabetic retinopathy (PDR) is controversial. VEGF seems to play a central role in mediating microvascular pathology in proliferative diabetic retinopathy (PDR). Recently, a +405 G/C VEGF polymorphism was shown to be associated with PDR. The aim of the current study(More)
OBJECTIVE To evaluate the effect of adjunctive intraocular triamcinolone acetonide (TA) in silicone-filled eyes on outcomes of vitreoretinal surgery for proliferative vitreoretinopathy (PVR). DESIGN Prospective, randomized, controlled clinical trial. PARTICIPANTS Seventy-five eyes with rhegmatogenous retinal detachment and PVR grade C (posterior,(More)
A total of 136 type 2 diabetic patients with nonproliferative and 94 patients with proliferative diabetic retinopathy (PDR) without nephropathy were studied. The DD genotype of the angiotensin-converting enzyme polymorphism was more common in the PDR group (P<0.001). In multivariate regression, the association remained significant (OR=3.516).
