Iris cyst secondary to latanoprost mimicking iris melanoma.
PURPOSE: To report an ocular side effect of topical latanoprost therapy. DESIGN: Single interventional case report. METHODS: A 73-year-old woman on latanoprost for primary open-angle glaucoma developed an iris cyst simulating an iris melanoma. RESULTS: The lesion disappeared over 8 weeks when latanoprost was stopped. CONCLUSIONS: In managing patients with iris-pigmented lesions, the list of medications should be reviewed. If the patient takes latanoprost, a trial off latanoprost is warranted.

Long anterior zonules and pigment dispersion.
PURPOSE: To describe pigment dispersion associated with long anterior zonules. DESIGN: Multicenter observational case series. METHODS: Fifteen patients, seven of whom were treated for glaucoma or ocular hypertension, were identified with long anterior zonules and pigment dispersion. Transmission electron microscopy was performed on one anterior capsule specimen. RESULTS: All patients had anterior zonules that inserted centrally on the lens capsule. Signs of pigment dispersion included corneal endothelial pigmentation, loss of the pupillary ruff, and variable trabecular meshwork pigmentation. Ultrasound biomicroscopy verified the lack of posterior iris insertion and concavity. There was no exfoliation material. Transmission electron microscopy showed zonular lamellae with adherent pigment granules, and no exfoliation material. CONCLUSIONS: Long anterior zonules inserted onto the central lens capsule may cause mechanical disruption of the pigment epithelium at the pupillary ruff and central iris leading to pigment dispersion.
