This 80YOF was initially seen with asymptomatic retinoschisis in her left eye. When examined 1.5 years later on 7/13/21, she remained asymptomatic, but the schisis cavity had enlarged in all dimensions.
Another six months later (1/5/22), the schisis cavity continued to enlarge in all dimensions with the formation of an early outer layer hole. Most recently (7/20/22), the outer-layer hole enlarged, and the schisis spontaneously collapsed, essentially resolving itself. Continued observation was recommended.
Learning Points:
Schisis cavities can enlarge, and in these cases, prophylactic treatment, including thermal laser, does not prevent further spread. Schisis very rarely progresses into the fovea (Byer Ophthalmology 1986;93:1127-1137) and even then is compatible with preserved central vision as long as the outer layer remains attached (Watzke et al 2013;33:606-612).
