Abstract:
Adult-onset foveomacular vitelliform dystrophy (AOFVD) is a clinically heterogeneous maculopathy that may mimic other conditions and be difficult to diagnose. It is characterized by late onset, slow progression and high variability in morphologic and functional alterations. Diagnostic evaluation should include careful ophthalmoscopy and imaging studies. The typical ophthalmoscopic findings are bilateral, asymmetric, foveal or perifoveal, yellow, solitary, round to oval elevated subretinal lesions, often with central pigmentation. The lesions characteristically demonstrate increased autofluorescence and hypofluorescent lesions surrounded by irregular annular hyperfluorescence on fluorescein angiography. Optical coherence tomography studies demonstrate homogenous or heterogeneous hyperreflective material between the retinal pigment epithelium and the neurosensory retina. The visual prognosis is generally favorable, but visual loss can occur from chorioretinal atrophy and choroidal neovascularization.
