Diagram of the human eye showing macula and fovea. Although J. D. Gass originally identified four types of idiopathic juxtafoveolar retinal telangiectasis in 1982, contemporary researchers describe three types collectively known as idiopathic juxtafoveal telangiectasia: macular telangiectasia type 1, macular telangiectasia type 2, and macular telangiectasia type 3.
Dilated blood vessels can also develop on the legs, although when they occur on the legs, they often have underlying venous reflux or "hidden varicose veins" (see Venous hypertension section below). When found on the legs, they are found specifically on the upper thigh, below the knee joint and around the ankles.
Angiomas and numerous abnormal, small, dilated telangiectatic vessels with thickened, sclerotic and calcified walls have been found in those brain areas which also show calcifications.

Rarely, only one eye is affected. In the acute stage, lasting a few weeks, the affected eye demonstrates an oedematous appearance of the nerve fiber layer, especially in the arcuate bundles and enlarged or telangiectatic and tortuous peripapillary vessels (microangiopathy).
Prominent blood vessels (telangiectasia) over the white of the eyes usually occur by the age of 5–8 years, but sometimes appear later or not at all. [7] The absence of telangiectasia does not exclude the diagnosis of A–T. Potentially a cosmetic problem, the ocular telangiectasia do not bleed or itch, though they are sometimes misdiagnosed ...
While sitting in the lecture hall during my second year of medical school, I noticed colored lights flashed in the corner of my right eye. At first, I wasn’t sure what was happening, but I knew ...
The eye develops in utero during the first three months of pregnancy, and a gap called the choroidal fissure appears at the bottom of the stalks that eventually form the eye, the AAO explains.
