PURPOSE To assess the macular thickness changes after cataract surgery in diabetic patients using optical coherence tomography (OCT). METHODS We retrospectively reviewed the records of 104 diabetic patients who underwent cataract surgery. We examined the changes of macular thickness using OCT before cataract surgery and 1 week, 1-, 2- and 6-months after surgery. The central subfield mean thic...

AIMS To evaluate the scanning retinal thickness analyser (RTA), a novel non-invasive imaging instrument, in diagnosing and quantitatively characterising diabetic macular oedema, and to investigate the relation between central macula thickness measured by RTA and other clinical examinations. METHODS Central macular thickness was measured using the RTA in 40 normal subjects and 60 patients with...

PURPOSE To report the short term anatomical and visual acuity response after intravitreal injection of bevacizumab in patients with proliferative diabetic retinopathy. METHODS Ten eyes having proliferative diabetic retinopathy were treated with at least one intravitreal injection of bevacizumab, 1.25 mg in 0.05 mL. Patients underwent complete ophthalmologic evaluation at baseline and follow u...

Introduction: Because of bilateral involvement in many cases with diabetic macular edema, Intravitreal bevacizumab injection perform in both eyes. There are some reports of therapeutic effects in the fellow eye after monocular injection of anti-vascular endothelial growth factors. In this study we describe a case of bilateral improvement of diabetic macular edema following unil...

BACKGROUND To assess the ability of the Chromatest in investigating diabetic maculopathy. METHOD Patients with Type 2 diabetes and no concurrent ocular pathology or previous laser photocoagulation were recruited. Visual acuities were assessed followed by colour contrast sensitivity testing of each eye using Chromatest. Dilated fundoscopy with slit lamp biomicroscopy with 78 D lens was then pe...

Neovascularization at the disc (NVD) is the most serious complication in diabetic retinopathy, and leads to vitreous hemorrhage and tractional retinal detachment. We report two cases of spontaneous regression of NVD in proliferative diabetic retinopathy. Two men (31 and 46 years old) with diabetes had NVD in both eyes. They were treated with panretinal photocoagulation on the left eye first, bu...

Purpose To introduce a hybrid wide-angle viewing-endoscopic vitrectomy, which we have reported, using a 3D visualization system developed recently. Subjects and methods We report a single center, retrospective, consecutive surgical case series of 113 eyes that underwent 25 G vitrectomy (rhegmatogenous retinal detachment or proliferative vitreoretinopathy, 49 eyes; epiretinal membrane, 18 eyes...

PURPOSE To determine whether or not a sub-Tenon's capsule injection of triamcinolone acetonide(TA) is an effective treatment for refractory diabetic macular edema after vitrectomy. METHODS Thirty-nine eyes of 26 patients with diabetic macular edema were injected with 20 mg TA into the sub-Tenon's capsule. The central macular thickness (CMT) measured by an optical coherence tomography (OCT) an...

PURPOSE To determine the presence of activated complement components in eyes affected by diabetic retinopathy. METHODS Eyes of 50 deceased donors with diabetic retinopathy and of 10 nondiabetic subjects with uveal melanoma (n = 6) or phthisical eyes (n = 4), as well as eyes of 16 deceased donors without diabetic retinopathy were subjected to immunohistochemical studies, using a panel of antib...

The permeability of the blood-ocular barrier was examined by fluorophotometry in adolescent and adult diabetic patients before the onset of retinopathy. The adolescent group consisted of 52 eyes of 52 insulin dependent diabetic patients aged 11 to 19 years and a control group of 10 eyes of 10 normal adolescents. The adult group consisted of 74 eyes of 74 non-insulin dependent diabetics and a co...
