A 29-YEAR-OLD woman was seen in June 1997, and a cystic mass on the left iris, angle of the anterior chamber, and the anterior ciliary body face was found (Figure 1). The cyst was monitored using findings from B-scan ultrasonography (Figure 2) and the size of the cyst increased over the next 6 months (Figure 3). She had undergone a left penetrating keratoplasty following herpetic keratitis when she was 10 years old. Although the keratoplasty was performed as an elective procedure, the donor material was 91 years old when transplanted, and the endothelial status was monitored annually by specular microscopy.
