Massive epithelium-lined inclusion cysts after scleral buckling.
Two patients with massive epithelium-lined inclusion cysts of the orbit became symptomatic five and 16 years after scleral buckling. Each patient described diplopia and displacement of the previously treated eye. An orbitotomy in the first patient disclosed a loculated epithelium-lined inclusion cyst that extended posteriorly from the insertion of the inferior rectus muscle nearly to the apex of the orbit. In the second patient, a loculated epithelium-lined inclusion cyst extended into the superior nasal portion of the orbit from its origin near the insertions of the superior and medial recti muscles. We speculated that epithelial cells of the conjunctiva were shed at the time of scleral buckling and became lodged in the exposed sulcus created by the surgical retraction of Tenon's capsule. Here they proliferated and formed the large epithelium-lined cysts. In each patient, removal of the cyst was followed by a decrease in diplopia as the displaced globe returned toward its normal position.
