This 9YO female was referred for an asymptomatic lesion in her left eye. She was found to have a large pars plana cyst in the temporal periphery.
Learning Points:
Pars plana cysts are localized to the pars plana region, commonly along a single ora bay. They form when the epithelial cell layers separate between the non-pigmented ciliary epithelium and pigmented epithelium, or solely within the pigmented epithelium.
Although they are benign findings, they need to be differentiated from retinal detachment or retinoschisis.
