Optical coherence tomography of adult-onset fovemacular vitelliform dystrophy.

Adult-onset foveomacular vitelliform dystrophy is characterized by a focal, round or oval shaped, subretinal foveal yellow lesion that presents bilaterally and usually symmetrically in the fourth or fifth decade of life. In addition to clinical observation, diagnosis of the disease process has until now been assisted by electrophysiological and fundus fluorescein studies. Two cases are presented that correlate the clinical fundus appearance with optical coherence tomography findings and describe the location of the yellow vitelliform material.
