This 55YO male was referred for an asymptomatic possible retinal detachment in his right eye. Vision was 20/30.
Optos color RG imaging shows superotemporal degenerative retinoschisis with two outer-layer holes (OLHs). A broad band of pigmented chorioretinal scarring is noted along the posterior edge of the schisis.
OCT scanning through the smaller outer layer hole inferiorly shows the elevated edges of the OLH with the overlying inner schisis cavity. Despite the posterior pigment suggesting a demarcation line, no detachment of the outer layer was noted, and observation was recommended.
Learning Points:
A combined schisis-retinal detachment occurs when degenerative schisis contains both inner- and outer-layer breaks, essentially forming a full-thickness break that allows liquid vitreous to reach the subretinal space.
