A comparative study in healthy subjects and diabetic patients of the mydriatic response to topical tropicamide 0.5% with and without added phenylephrine 10% is reported. The findings indicate that diabetic pupils respond relatively poorly to tropicamide alone but adequately and completely to the drug combination. The pupils of diabetic patients whose eyes had previously received laser treatment...

The outcome of the removal of silicone oil from previously vitrectomised diabetic eyes was studied in a series of 25 eyes in 24 patients. Originally the patients presented with complex retinal detachments associated with proliferative diabetic retinopathy and all had reattached retinas after the initial operation. During the silicone tamponade, a number of complications had occurred. Cataract h...

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: 26 million people were estimated to be affected by diabetes in 2010 across the globe. Diabetic macular edema (DME) is the most important cause of visual impairment due to diabetic retinopathy. Optical Coherence Tomography (OCT) is a non-invasive modality which produces cross-sectional or three-dimensional, high-resolution images of the retinal layers and quantitative assessment of r...

PURPOSE To compare nonmydriatic stereoscopic Optomap ultrawide field images with dilated stereoscopic Early Treatment Diabetic Retinopathy Study 7-standard field 35-mm color 30-degree fundus photographs (ETDRS photography) and clinical examination for determining diabetic retinopathy (DR) and diabetic macular edema (DME) severity. DESIGN Single-site, prospective, comparative, instrument valid...

OBJECTIVE To compare the effectiveness of tele-screening using a novel enhanced retinal thickness analyzer (RTA) with onsite routine ophthalmologic examination for diabetic retinopathy. RESEARCH DESIGN AND METHODS A consecutive series of 31 eyes from diabetic patients were included. All underwent ophthalmologic examination, including stereoscopic dilated funduscopy and scanning with the RTA. ...

purpose: to report an iranian patient with diagnosis of oguchi disease associated with diabetic retinopathy. methods: a 50-year-old diabetic woman with night blindness was referred to our clinic. complete ophthalmic examination including ophthalmoscopy after dark adaptation and paraclinic evaluations such as fluorescein angiography and electroretinography were performed. results: in the both ey...

PURPOSE To report the efficacy and safety of combined intravitreal dexamethasone implant and micropulse laser for anti-VEGF resistant diabetic macular edema. PATIENTS AND METHODS Prospective, non-controlled study that was conducted for twenty eyes with center-involved diabetic macular edema not responding to anti-VEGF therapy. Ozurdex intravitreal implant was injected to all eyes with subsequ...

The course of diabetic retinopathy following cataract extraction was studied retrospectively in 89 patients (89 eyes). Cataract extraction was extracapsular in 12 eyes (13.5%), extracapsular with intraocular lens implantation in 37 (41.6%), and intracapsular in 40 (45%). In 55 eyes (61.8%) there was no change in the retinal status after surgery, and in 34 (38.2%) there was progression of diabet...

OBJECTIVE To evaluate intravitreal injection of triamcinolone acetonide before laser panretinal photocoagulation (PRP) in the treatment of proliferative diabetic retinopathy. METHODS This interventional case series included 9 patients with bilateral proliferative diabetic retinopathy. One eye received intravitreal triamcinolone before PRP (injected eye) and the other, PRP alone (control eye)....
