Pseudovitelliform macular degeneration
G. A. Fishman, S. Trimble, M. F. Rabb and M. Fishman
Three patients with vitelliform-like macular lesions had normal
electroooculogram (EOG) light-peak/dark-trough ratios, unlike typical cases
of vitelliform dystrophy (Best macular dystrophy). Leakage of fluorescein
dye from perifoveal cappillaries implicated an increased permeability of
these vessels as the probable cause for the vitelliform-appearing lesions.
All patients with vitelliform lesions demonstrating normal EOG ratios
should have an evaluation by fluorescein angiography to rule out a
diagnosis of what we prefer to call pseudovitelliform macular degeneration.
