| Summary: | Idiopathic juxtafoveolar retinal telangiectasis (IJRT), also known as idiopathic macular telangiectasia (IMT), refers to a heterogeneous group of well recognized clinical entities characterized by telangiectatic alterations of the juxtafoveolar capillary network of one or both eyes, but which differ in appearance, presumed pathogenesis, and management. Classically, three groups of IJRT are identified. Group 1 is unilateral, easily visible telangiectasis occurring predominantly in males, and causing visual loss as a result of macular edema. Group 2, the most common, is bilateral occurring in both middle-aged men and women, and presenting with telangiectasis that is more difficult to detect on biomicroscopy, minimal exudation, superficial retinal crystalline deposits, and right-angle venules along with characteristic and diagnostic angiographic and optical coherence tomography (OCT) features. Vision loss is due to retinal atrophy, not exudation, and subretinal neovascularisation (SRNV) is common. Group 3 is very rare characterized predominantly by progressive obliteration of the perifoveal capillary network, occurring usually in association with a medical or neurologic disease. This article presents a current review of IJRT, including the classification, clinical features, pathogenesis, complications, differential diagnosis, and treatment modalities. |
