Figure 1: (a) Fundus autofluorescence imaging did not show the typical foveal darkening due to absorption of the excitation light by macular pigment in patient 1. Patient 2 had only a slightly reduced foveal attenuation of autofluorescence. (b) The foveal avascular zone was absent in the flourescein angiogram in patient 1. Patient 2 had a normal aspect in fluorescein angiography. (c) SD-OCT showed reduced foveal pit and continuity of inner retinal layers in both patients. Photoreceptor layer had a normal thickness centrally in patient 1 (arrow).
