Visual Psychophysics in Diabetic Retinopathy

INTRODUCTION Irreversible and severe visual loss may represent the end of long lasting diabetic retin-opathy. The progression of visual impairment and the quantification of final residual visual function are currently determined by means of diagnostic tests which rely on the physiological and mathematical principles of psychophysics. The best known among these tests is the quantification of vis...

Visual fields in patients who have undergone vitrectomy for complications of diabetic retinopathy. A prospective study

BACKGROUND To determine the extent of visual field loss in patients who had required a pars plana vitrectomy secondary to complications of proliferative diabetic retinopathy. METHODS Patients that had undergone a vitrectomy on at least one eye for treatment of either vitreous haemorrhage or tractional retinal detachment were selected for study. ETDRS acuity and Humphrey binocular Esterman vis...

Visual Prognosis of Proliferating Diabetic Retinopathy.

SINCE we are not yet able to prevent retinal changes in diabetic patients we must be content to accept, lessen, or slow the progress of these degenerative retinal vascular changes. The latest method of lessening them is the " Houssay phenomenon", which is said to have a favourable effect in diabetic retinopathy through destruction of the pituitary gland. The percentage of diabetic patients with...

Risk Factors for High-Risk Proliferative Diabetic Retinopathy and Severe Visual Loss: Early Treatment Diabetic Retinopathy

RESULTS. The baseline characteristics identified as risk factors for high-risk PDR were increased severity of retinopathy, decreased visual acuity (or increased extent of macular edema), higher glycosylated hemoglobin, history of diabetic neuropathy, lower hematocrit, elevated triglycerides, lower serum albumin, and, in persons with mild to moderate nonproliferative retinopathy, younger age (or...
