Summary

Idiopathic Parafoveal Telangiectasia (IPT) [also known as Idiopathic Perifoveal Telangiectasia, Idiopathic Juxtafoveal Telangiectasia (IJT, JFT) and Macular Telangiectasia (MacTel)] is a disorder of unknown etiology. IPT is classified as Group 2A in the Gass classification of macular telangiectasias (Reference 1,5) - a bilateral, but not always symmetric disorder. It is characterized in its early stages by dilation and loss of parafoveal capillaries accompanied by angiographic leakage, "right angle" venules, central and parafoveal intraretinal cysts.
