Optical Coherence Tomography Changes in a Patient with Adult-Onset Foveomacular Vitelliform Dystrophy

We present a case of adult-onset foveomacular vitelliform dystrophy (AFMVD) in a 62-year-old man. Fundus examination revealed subretinal depositions of yellowish material within themacula. During the 4-year follow-up period, the best corrected visual acuity (BCVA) in the right eye did not change; the BCVA in the left eye gradually deteriorated from 0.5 to 0.08. Ophthalmoscopic findings showed no change in the subretinal yellowish deposit in the right eye. Atrophic changes gradually developed in the left eye; vitelliruptive degeneration was observed 3.5 years after the initial visit. Optical coherence tomography (OCT) revealed progressive accumulation of hyper-reflective material in the subretinal space and vitelliruptive degeneration was observed in the left eye. The left central macular thickness decreased between the initial and last visits. The subretinal hyper-reflective materials were reabsorbed in both eyes during the natural course of the disease. Thus, OCT was useful in visualizing the subretinal lesions in a patient with AFMVD.
