Filter by:Randomized double-blinded two-year intervention study with topical application of latanoprost or placebo eye drops in patients with diabetic retinopathy.
This exploratory study will compare the effects of ranibizumab treatment with conventional macular laser therapy for patients with diabetic macular oedema. The study hypothesises that treatment with ranibizumab may be superior to laser treatment in terms of improving vision and decreasing retinal thickness. Patients will be randomised to receive either repeated injections of ranibizumab every 4 weeks for 48 weeks or macular laser therapy every 12 weeks for 48 weeks. At baseline, and then at 12, 24 and 48 weeks, patients will undergo detailed testing to provide information on the structure and function of the retina with both of these treatments.
The purpose of this study is to identify alterations of the blood-retinal barrier (BRB) in diabetic retinas using a novel non-invasive approach based on the Fourier domain high-definition optical coherence tomograph (OCT).
This study is designed to report 3-year result of triple therapy of vitrectomy, intravitreal triamcinolone and macular laser photocoagulation for intractable diabetic macular edema. Previously author reported 1-year result(Am J Ophthalmol. 2007 Dec;144(6):878-885. Epub 2007 Oct 15.).
The purpose of this study was to assess the effect of ranibizumab in reducing intraoperative vitreous haemorrhage during pars plana vitrectomy, thus facilitating surgery and improving its anatomical and functional results in patients with advanced proliferative diabetic retinopathy and traction retinal detachment.
This study will asses sthe safety of pegaptanib sodium in patients with diabetic macular edema. The hypothesis is that pegaptanib is safe and efficacious in patients with diabetic macular edema.
Pt. 1 Diabetic retinopathy is a common eye condition among diabetic adults and can lead to severe vision impairment and even blindness. African Americans are more likely to have vision loss from diabetic retinopathy due to a variety of factors, including cultural barriers to care. The investigators aim to increase the rates of eye exams in diabetic African American adults by providing culturally relevant home-based interventions. These interventions will increase the knowledge about diabetes and the eyes and the awareness of ocular risks due to diabetes. 206 African American adults, over the age of 65, with diabetes will be recruited from primary care clinics at Thomas Jefferson and Temple University. Eligible patients who consent to participate will have baseline information taken about medical and ocular history, understanding of diabetes and a hemoglobin A1C level obtained. The subjects will then be randomized to one of two treatment conditions: Behavioral Activation or Supportive Therapy, each of which will be delivered over 4 sessions. Behavioral Activation will consist of educational materials, referral assistance for eye clinics, and addressing patient specific barriers to care. Supportive Therapy will consist of supportive but non-directional interaction with the patient exploring the impact of aging and diabetes on the patient's life. The investigators hypothesize that more patients who receive Behavioral Activation will have a dilated fundus exam (the primary outcome variable), understand the risks of diabetic complications and feel less depression then subjects who receive Supportive Therapy.
The purpose of this study is to identify eyes that show worsening and disease progression (progressor phenotypes).
Prevalence of Diabetic Retinopathy in São José do Rio Preto-SP-Brazil Abstract Objective: To determine the prevalence and characteristics of diabetic retinopathy (DR) among patients from São José do Rio Preto-SP-Brazil . Local: Departamento de Retina e Vítreo do Hospital do Olho de Rio Preto (HORP) Methods: Design: population-based cross-sectional study. The study sample, of 710 patients was derived from the HIPERDIA (Diabetes and High-blood pressure social health care program) of São José do Rio Preto . All patients , known to have diabetes , underwent an eye examination by biomicroscope and indirect ophthalmoscope to check for any signs of DR through dilated pupils. Participants were also interviewed and examined to determine their demographic characteristics, medical conditions and the realization of previous fundoscopic eye examination. Statistical studies were done with t -Student test , Fisher test or chi-square test.
The purpose of this study is to examine and compare, prospectively, best corrected visual acuity (BCVA) outcomes and complications of a cohort of patients with Proliferative Diabetic Retinopathy and Tractional Retinal Detachment not involving macula undergoing pars plana vitrectomy (PPV) or conventional management (panretinal photocoagulation).
