A 36-year-old man presented with an orbital cyst in the left eye three years after retinal detachment surgery with scleral buckling. The cyst was in the anteromedial aspect of the orbit resulting in ptosis, elevated intraocular pressure (IOP) and limited ocular motility. The cyst was totally excised and ptosis was corrected by frontalis sling procedure. Histopathology of the specimen revealed a solitary cyst lined by cuboidal epithelial cells. Some epithelial cells contained Periodic acid-Schiff (PAS)-positive granules. Accordingly, the diagnosis was a sudoriferous cyst. Sudoriferous cyst of the orbit is rare and often congenital. This case report illustrates that orbital sudoriferous cyst can develop after scleral buckling.
