MORPHOLOGY AND FUNCTIONAL CHARACTERISTICS IN ADULT VITELLIFORM MACULAR DYSTROPHY

Abstract

AVMD is characterized by late onset, slow progression, good prognosis, and high variability of morphologic and functional abnormalities resulting frequently in misdiagnosis. Autofluorescence findings indicate lipofuscin accumulation in the yellow lesion. Electroretinography revealed a generalized cone system dysfunction with increasing severity toward the fovea.
