Findings

No curated finding names macular telangiectasia type 1 yet. Everything below is reference data from Mondo, HPO and GenCC, not evidence about what affects it.

Definition

A rare, acquired, macular telangiectasia characterized by unilateral (rarely bilateral) abnormally dilated and tortuous capillaries around the fovea, associated with multiple arteriolar and venular aneurysms, lipid depositions, and intra-retinal cystoid degeneration. It leads to vision loss due to macular edema with hard exudates.
