Overview


Idiopathic juxtafoveal retinal telangiectasia (IJT) refers to a group of eye conditions characterized by dilated or twisting blood vessels (telangiectasia) and defective capillaries (tiny blood vessels) near the fovea in the retina. The fovea has the biggest number of special retinal nerve cells, called cones, which enable sharp, daytime vision. In IJT, the telangiectasias cause fluid or crystal buildup and swelling, impairing reflection of light. This results in progressive vision loss.[1][2][3][4] It may be congenital (present at birth) or can develop during the lifetime (acquired).[2] The different types of IJT are distinguished by their features and treatment options.[5] Laser photocoagulation maybe helpful in treating vision loss for individuals with certain types of IJT.[2]
