Ultrawide-field Swept Source-OCT Angiography of Retinitis Pigmentosa

A 42-year-old man diagnosed with retinitis pigmentosa (RP) underwent widefield Optos imaging and swept-source OCT angiography (SS-OCTA) (24 × 20 mm SS-OCTA; BM-400K BMizar, TowardPi Medical Technology) examination. A, Fundus image revealed classic features of RP, including intraretinal pigmentation, waxy pallor of the optic disc, and attenuated retinal blood vessels. B, The retinal flow image displayed perfusion limited to the posterior pole with vascular remodeling at the borders. C, The retinal structure image showed intraretinal pigmentation outside the arcade (red arrows) and the empty shells of nonperfused "ghost" vessels (yellow arrows) (Magnified version of Fig A-C is available online at www.aaojournal.org).
