This 33YO patient presented with a prominent inferior retinal detachment associated with superotemporal retinoschisis with a large outer layer hole (OLH). The OLH was surrounded by laser-like chorioretinal scarring, although the patient denied prior laser surgery.
At vitrectomy, a superonasal gutter of peripheral detachment extended to an equatorial tear at 10:30 (not visualized in these images). The OLH and schisis were not detached.
Learning Points:
Patients with degenerative retinoschisis and associated inner- and outer-layer holes are at risk of rhegmatogenous retinal detachment.
Despite our patient probably undergoing prior prophylactic laser photocoagulation around the outer layer hole, he still developed a retinal detachment from a presumed new retinal tear outside the area of schisis.
