Telangiectasia

 

a stable dilation of superficial blood vessels, principally capillaries, of the skin and mucous membranes. The condition may be acquired, but it is usually congenital and is often hereditary. Telangiectases are bluish red spots of varying shapes that generally appear on the face or shins. They may bleed if situated on the mucous membranes of the upper respiratory tract or alimentary canal. Telangiectasia is treated by electrocoagulation or cryotherapy.

Detection of vascular occlusive changes, vascular dilatation, emergence of collaterals, and microaneurysmal changes in the capillaries are the microscopic determinants of the disease.1,2 Radiation retinopathy is characterized by parenchymal inflammation, leukocyte pooling in the capillaries, glial hypertrophy, necrotic and gliotic changes, neuronal swelling and degeneration.6 Microscopic characteristics of the final phase of radiation retinopathy are co-existence of regenerated vessels and ischemic fields.7 FFA shows capillary nonperfusion, and this finding is the gold standard to demonstrate radiation retinopathy.7 Our patient had enlargement of the foveal avascular zone, perifoveal capillary telangiectasia and widespread venous beading in both eyes on FFA.
