Diabetic retinopathy is a complication of diabetes, caused by high blood sugar levels damaging the back eye (retina). It can cause blindness if left undiagnosed and untreated. However, it usually takes several years for diabetic to reach stage where could threaten your sight. damage vessels in tissue at Poorly controlled risk factor. Early symptoms include floaters, blurriness, dark areas visio...

OBJECTIVE To determine whether non-mydriatic Polaroid retinal photography was comparable to ophthalmoscopy with mydriasis in routine clinic screening for early, treatable diabetic retinopathy. DESIGN Prospective study of ophthalmoscopic findings according to retinal camera screening and ophthalmoscopy and outcome of referral to ophthalmologist. SETTING Outpatient diabetic clinics of three t...

Background and Purpose: Microaneurysms and fibrinoid necrosis of cerebral cortical arteries have been reported to be related to the pathogenesis of intracerebral hemorrhage associated with cerebral amyloid angiopathy. To elucidate the pathogenesis of such vascular lesions, we conducted the present study. Methods: Five hundred serial sections from brain tissue of a patient with severe amyloid an...

Background and Purpose—Retinal microvascular abnormalities reflect cumulative small vessel damage from elevated blood pressure and may reflect subclinical cerebral microvascular changes. We examined their associations with MRI-defined cerebral infarcts. Methods—Population-based, cross-sectional study of 1684 persons 55 to 74 years of age without a history of clinical stroke, sampled from 2 US s...

PURPOSE To establish adaptive optics scanning laser ophthalmoscopy as a method to detect and characterize microscopic signs of diabetic retinopathy in capillaries and cone photoreceptors in the parafovea. METHODS Recently, adaptive optics scanning laser ophthalmoscope (AOSLO) has enabled noninvasive assessment of photoreceptors, capillaries, and leukocytes in the retinas of live human subject...

PURPOSE To determine whether the retina is hypoxic in early stages of diabetic retinopathy in cats and to correlate intraretinal PO2 with fluorescein angiographic and histologic alterations. METHODS Intraretinal PO2 was measured with microelectrodes in three cats with long-standing diabetes (>6 years) that had been followed with fluorescein angiographs every 6 months. Average PO2 in the inner...
