We describe spectral-domain optical coherence tomography (OCT; Heidelberg Spectralis) imaging of 3 patients with Niemann-Pick disease type B. This expands the range of previously reported anatomical correlates of the ophthalmoscopic macular halo surrounding the “cherry-red spot.”1
A 34-year-old man with Niemann-Pick disease type B was referred for ophthalmic evaluation. Best-corrected visual acuity was 20/30 OD and 20/25− OS. Dilated fundus examination revealed normal-appearing optic nerves, tortuous retinal veins, and venous beading. There were striking white macular halos surrounding the normal red foveal depressions in both eyes (Figure 1A). Spectral-domain OCT revealed a layer of hyperreflective retinal tissue at the shoulders of the foveal depression. The hyperreflective tissue extended across the foveal floor but was markedly thinner centrally (Figure 1A).
