PURPOSE To study the 4 years incidence of diabetic retinopathy in patients with type II diabetes and effective factors on its progression. METHODS Among diabetic patients referred to Yazd Diabetes Research Center, 120 patients with type II diabetes without diabetic retinopathy were selected. After complete ophthalmic examination, fasting blood sugar (FBS), postprandial blood sugar, triglyceri...

Diabetic retinopathy is one of the leading causes of blindness in working-age individuals. Diabetic patients with proteinuria or those on dialysis usually present severe forms of diabetic retinopathy, but the association of diabetic retinopathy with early stages of diabetic nephropathy has not been entirely established. A cross-sectional study was conducted on 1214 type 2 diabetic patients to d...

OBJECTIVES (a) To report on the basic parameters of retinal blood flow in a population of diabetic patients with and without retinopathy and non-diabetic controls; (b) to formulate a haemodynamic model for the pathogenesis of diabetic retinopathy from this and other studies. DESIGN Laser-Doppler velocimetry and computerised image analysis to determine retinal blood flow in a large cross secti...

INTRODUCTION Diabetes mellitus (DM) is associated with serious complications including macro- and microvascular problems such as diabetic retinopathy. Coronary involvement in diabetic patients is believed to be a consequence of microvascular complications. However, the available data are inconclusive and scarce. This study aimed to evaluate the probable association between diabetic retinopathy ...

PURPOSE To investigate retinal changes prior to vascular signs in patients with type 2 diabetes without diabetic retinopathy or with mild non proliferative diabetic retinopathy. METHODS A cross-sectional study was performed in three groups: patients without diabetes, patients with type 2 diabetes without diabetic retinopathy, and patients with diabetes with mild diabetic retinopathy. Analysis...

OBJECTIVE Diabetic retinopathy is a major cause of blindness. To determine whether retinopathy itself or only its severity aggregates in families, we examined the occurrence and severity of diabetic retinopathy in Mexican-American siblings with type 2 diabetes. RESEARCH DESIGN AND METHODS Using stereoscopic fundus photography of seven standard fields, we measured retinopathy in 656 type 2 dia...

Few epidemiological data exist regarding the correlation of anatomic measures of diabetic retinopathy and nephropathy, especially early in the disease processes. The aim of this study was to examine the association of severity of diabetic retinopathy with histological measures of diabetic nephropathy in normoalbuminuric patients with type 1 diabetes. The study included participants (n = 285) in...
