PURPOSE To ascertain whether intravitreal triamcinolone given for subretinal neovascularization is associated with an ocular pressure rise. METHODS A total of 113 patients with angiographically proven subretinal neovascularization were enrolled into a prospective study of the effects of intravitrea triamcinolone. Intraocular pressure was one of the(More)
PURPOSE The purpose of this study was to investigate choroidal perfusion in glaucoma, using histological and angiographic techniques. METHODS We examined the choroidal vasculature in clinicopathological slides from 25 cases of primary open-angle glaucoma, five cases of optic atrophy, and 18 normal eyes. We measured choroidal thickness at fixed distances(More)
PURPOSE To investigate the association of cup-to-disc ratio (CDR), intraocular pressure (IOP), and primary open-angle glaucoma (POAG) with the site of retinal venous occlusion (RVO) and optic nerve head swelling (ONHS). DESIGN Prospective observational case series. PARTICIPANTS Four hundred fifty consecutive cases from a single tertiary referral center.(More)
PURPOSE To examine quality of life and associated factors in people with Age-Related Macular Degeneration (AMD). METHODS One hundred and forty-five AMD participants (mean age 78.0 ± 7.7 years) and 104 age- and gender- matched controls (mean age 78.1 ± 5.8 years) comprised the study populations for this case-control study. Depressive symptoms were measured(More)
The capillaries in normal and short term (30 days) streptozotocin-diabetic rats were studied with quantitative light and electron microscopy. The streptozotocin treatment caused capillary dilatation, endothelial proliferation, and endothelial swelling. These ultrastructural changes occurred in existing capillaries, since light microscopy showed no(More)
BACKGROUND Visual outcomes of patients following vitrectomy and peeling of visually significant epiretinal membranes were assessed to determine the influence of specific perioperative factors and surgical complications on final visual acuity and functional vision. METHODS In an unmatched, consecutive surgical series, vitrectomy and membrane peeling were(More)
OBJECTIVE To investigate the significance of optic nerve head swelling (ONHS) in relation to the pattern of vascular nonperfusion, visual acuity (VA), and demographic profile in retinal venous occlusions (RVOs) occurring within the optic nerve. METHODS Cases of RVO occurring within the optic nerve were divided on the basis of the presence (105 cases) or(More)
PURPOSE Macular schisis or detachment is frequently observed in eyes with optic pits or colobomas. Although spontaneous resolution of the maculopathy has been reported, concurrent changes in the optic nerve coloboma have not. We report three cases of atypical optic nerve colobomas in which dynamic optic nerve changes coincide with the development and(More)
PURPOSE To examine the safety and efficacy of limited macular translocation followed by laser photocoagulation in the management of subfoveal choroidal neovascularization (CNV) in age-related macular degeneration (AMD). METHODS A prospective study was conducted on eight consecutive patients undergoing limited macular translocation followed by laser(More)
