Vitelliform lesions associated with retinal pigment epithelial detachment.

Two patients with bilateral vitelliform macular lesions had normal electro-oculogram findings. The fluorescein angiograms showed retinal pigment epithelial detachment. Detachment of the retinal pigment epithelium associated with lipid and/or protein accumulation within the subpigment epithelial space represents another mechanism by which a lesion ophthalmoscopically similar to that seen in classical Best's disease can be produced.
