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

ABSTRACT

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.
