During vitrectomy for a macular pucker, this intraoperative photo shows an incidental finding of 3-4 pars plana cysts in the superior quadrant found on scleral depression. The cysts were oval, and the inner cyst walls appeared smooth and transparent. Anteriorly, they extended variably over about one-half of the pars plana towards the ciliary processes.
Learning Points:
Pars plana cysts are found in up to 18% of eyes and are more prevalent in the older population. They typically appear as ovoid elevations with a smooth, taut surface.
Pars plana cysts are usually acquired and represent a normal ocular aging change. While the cysts themselves are benign, they may occur secondary to ocular or systemic pathology, including retinal detachment, posterior uveitis, and multiple myeloma.
