Ciliary body melanocytoma with anterior segment pigment dispersion and elevated intraocular pressure

Purpose: To discuss a case in which melanocytoma of the ciliary body presen ted with widespread pigment dispersion and elevated intraocular pressure (I OP). Methods: A 64-year old woman presented with increased IOP and persistent an terior segment inflammation in her right eye. She had undergone a trabecule ctomy for uncontrolled IOP before presentation. Slit-lamp examination, goni oscopy, and ultrasound biomicroscopy revealed a ciliary body mass with exte nsion into the subconjunctiva in addition to widespread pigmentary dispersi on in the anterior segment. Enucleation of the right eye was performed for histopathologic evaluation, as a diagnosis of ciliary body melanoma was mad e on clinical examination. Results: Histopathologic findings were diagnostic of a melanocytoma of the ciliary body with necrosis and focal malignant transformation with extensio n of melanocytoma cells and melanophages into the subconjunctival space, tr abecular meshwork, and anterior chamber angle. Conclusion: Melanocytoma of the ciliary body is a rare intraocular tumor th at may present with pigment dispersion and secondary elevated IOP. Careful examination of the anterior segment is imperative in such cases.
