Macular telangiectasia type 2. a. Subtle parafoveal retinal pigment epithelium changes and right-angle venules are present early in disease. b. Corresponding late leakage of dye temporal to the fovea on fluorescein angiography (FA) without significant changes on optical coherence tomography (OCT; not shown). c. A fundus photo from a different patient shows hemorrhage and thickening temporal to the fovea with leakage on FA (not shown). d. OCT showing subretinal irregularities consistent with choroidal neovascularization (CNV). e. A later OCT from the same patient shows a cavitation space (arrow) developing over the treated CNV.
