A 70-YEAR-OLD man underwent pars plana vitrectomy for an epiretinal membrane in his left eye in 2001. The sclerotomies were closed with stitches of polyglactin 7-0 (Vicryl; Ethicon, Inc, Somerville, NJ) to produce a watertight X-shaped closure. Four months postoperatively, the patient noted a bleblike lesion under his superior eyelid (Figure 1). Visual acuity was 20/20 OS. The intraocular pressure was normal and the eye was quiet. The cystic lesion was removed under local anesthesia. The lesion was located in front of one of the temporal superior sclerotomies. There was no continuity between the cyst and the underlying sclera which was completely intact without any stitch. Analysis of the "hypopyon" revealed the presence of polymorphonuclear leukocytes without microorganisms. Findings from the histopathological examination of the wall of the lesion revealed an epithelial inclusion cyst of the conjunctiva (Figure 2).
