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)
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)
and 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)
AIMS To identify the contributory factors associated with different sites of occlusion and the presence or absence of optic nerve head swelling (ONHS). METHODS 874 cases of retinal venous occlusion (RVO) were prospectively examined at a tertiary referral centre and classified according to three defined sites of occlusion: arteriovenous crossing RVO(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)
The quantitative ultrastructure of capillaries in the rat retina was studied in order to establish control parameters for experimentally induced vascular disorders. A near perfect correlation teas found between the number of tight junctions and the mean lumen area of retinal capillaries. Comparisons between female pigmented and albino rats of the same age(More)
OBJECTIVES To quantify and categorize the lesions of neovascular age-related macular degeneration on the basis of fluorescein angiographic morphology. METHODS We retrospectively reviewed 3580 consecutive cases of neovascular age-related macular degeneration. The lesions were graded in terms of the location, size, and composition and categorized according(More)
