Coats' disease is an idiopathic ophthalmic condition caused by a defect in the development of retinal vasculature, characterized by retinal telangiectasis, haemorrhages, intraretinal and subretinal exudation. There are two pathological processes, which are evident in Coats' disease. The first consists of a breakdown of the bloodretinal barrier at the endothelial level, which causes plasma leaka...

A case of juxtafoveolar telangiectasia complicated by lamellar, retinal hole is reported and the pathogenesis discussed. This association is not commonly recognised.

Coats' disease is characterized by abnormal retinal vascular development (so-called 'retinal telangiectasis') which results in massive intraretinal and subretinal lipid accumulation (exudative retinal detachment). The classical form of Coats' disease is almost invariably isolated, unilateral and seen in males. A female with a unilateral variant of Coats' disease gave birth to a son affected by ...

PURPOSE To determine the optical coherence tomography (OCT) findings in eyes with group 2a idiopathic juxtafoveal retinal telangiectasis (IJRT). METHODS Forty-one eyes of 22 patients with nonproliferative group 2a IJRT were examined. OCT testing including retinal topographic mapping and analysis, and horizontal and vertical line scans, was obtained on each eye. RESULTS None of the 41 eyes h...
