Novel features of degenerative retinoschisis identified using ultra‐widefield multicolor channels: A review of 139 eyes

Background/Objective To utilize ultra‐widefield multimodal imaging (Optos PLC) to describe novel findings in degenerative retinoschisis. Methods This retrospective, non‐comparative case series of degenerative retinoschisis received a waiver of consent from Advarra IRB, Protocol 00066379. Initial ultra‐widefield pseudocolour, colour‐separated, autofluorescence, and peripheral OCT imaging were analysed for characterizing features. Results In total, 139 eyes were included. A hyporeflective reticular pattern associated with retinoschisis was seen on pseudocolour images in 39% of cases, but visible in 53% on green‐separated images. Fine hyper‐reflective foci were observed in 49%. In 27%, retinoschisis was confirmed with OCT. Conclusions Ultra‐widefield pseudocolour and green‐separated images are valuable for the diagnosis and characterization of degenerative retinoschisis. The findings described may prompt the evaluation of subtle retinoschisis with peripheral OCT.
