Supplementary Material for: Free-Floating, Pigmented Cysts in the Anterior Chamber Causing Ocular Hypertension

Purpose: The aim of this study was to describe the clinical and histopathological features of a 36-year-old male with hundreds of recurrent, unilateral, free-floating, pigmented cysts in the anterior chamber causing ocular hypertension. Procedures: The patient was referred to ocular oncology for blurry vision of the right eye and was found to have myriad pigmented, free-floating cysts in the anterior chamber and heavy pigmentation of the angle on gonioscopy. Anterior chamber washout was performed, and the fluid recovered was sent for pathological analysis. Results: The pathology report demonstrated rare nonpigmented epithelial cells, more consistent with iris stromal cysts or secondary implantation epithelial cysts. Conclusions: This paper highlights the first documented case of innumerable spontaneously occurring, unilateral, free-floating, pigmented cysts in the anterior chamber. While clinical diagnosis suggested iris pigment epithelial cysts, pathology suggested iris stromal cysts or secondary implantation epithelial cysts.
