Foveal pigment change
WebThese two patients were over 40 years of age. Two patterns of fundus pigmentary changes were present in this cohort: 7/11 had typical bone spicule-shaped pigment migration within the peripheral retina whereas 4/11 had widespread clumped pigmentary changes of nummular appearance at the level of the retinal pigment epithelium (Figure 2). WebResults: Foveal lesions varied from predominantly radial striations (3%), microcystic lesions (34%), honeycomblike cysts (8%), or their combinations (31%) to non-cystic-appearing foveal changes, such as pigment mottling (8%), loss of the foveal reflex (8%), or an atrophic-appearing lesion (8%).
