Atypical cotton-wool spots.
Atypical cotton-wool spots in four selected cases of diabetic retinopathy are discussed. The most striking characteristic distinguishing them from typical cotton-wool spots is their size, which ranges from about 2 to 4 disc diameters. They develop after stenosis or a complete obstruction of a first order arteriole at the point at which it emerges from the parent arterial branch. The size of the...
متن کاملRetinal cotton-wool spots: an early finding in diabetic retinopathy?
Five insulin dependent diabetic patients are reported on who had a few small retinal cotton-wool spots or 'soft exudates' either totally isolated or associated with fewer than 10 microaneurysms. These observations suggest that cotton-wool spots may be an early finding in diabetic retinopathy. Significant biological abnormalities in these patients were high levels of glycosylated haemoglobin and...
متن کاملCotton-wool spots and retinal light sensitivity in diabetic retinopathy.
In 14 eyes of 14 patients with diabetic retinopathy the light sensitivity of retinal cotton-wool spots was studied by computerised perimetry, and the visual field data were accurately correlated with the corresponding morphology as seen on fundus photographs and fluorescein angiograms. In 12 of the eyes the examinations were repeated within one year in order to follow changes in retinal light s...
متن کاملIntra-retinal Cotton Wool Spots and Their Relation to Epiretinal Membrane Contraction and Induced Retinal Distortion
Background: Idiopathic Epiretinal membranes (ERM) may cause a wide variety of retinal abnormalities due to tangential traction on the retinal surface. These tractional changes may lead to retinal vascular leakage and oedema or rarely, a mechanical blockage of the axoplasmic flow resulting in a cotton wool spot (CWS). Aim: To follow the pre-operative location and time course of disappearance of ...
متن کاملThe microperimetry of resolved cotton-wool spots in eyes of patients with hypertension and diabetes mellitus.
BACKGROUND Retinal cotton-wool spots (CWSs) are an important manifestation of retinovascular disease in hypertension (HTN) and diabetes mellitus (DM). Conventional automated perimetry data have suggested relative scotomas in resolved CWSs; however, this has not been well delineated using microperimetry. This study evaluates the retinal sensitivity in documented resolved CWSs using microperimetr...
