To study the different clinical presentation of the idiopathic juxtafoveolar retinal telangiectasis and its treatment with argon laser.We studied retrospectively nine eyes of eight patients, seen from 1990 to 1997, with diagnosis of idiopathic juxtafoveolar retinal telangiectasis. They have been studied with fluorescein angiography and treated with argon laser.The most frequent clinical presentation was large areas of retinal telangiectasis affecting the horizontal rafe temporal to the macula. The diagnosis was stabilised as regards clinical manifestation and after ruling out other causes. Six out of eight patient with visual disfunction for macular edema and exudation improved considerably after laser photocoagulation. In 3 patients the vascular abnormalities were progressive after the treatment.The idiopathic juxtafoveolar retinal telangiectasis with exudation is an uncommon disease, that causes visual disturbance, but may be treated with laser photocoagulation.
