Iris melanoma with increased intraocular pressure. Differentiation of focal solitary tumors from diffuse or multiple tumors.

A 70-year-old man presented with an apparent focal iris ciliary body mass and increased intraocular pressure. Fine needle aspiration biopsy 180 degrees from the main lesion demonstrated uveal melanoma cells in the angle. The eye was enucleated, and multiple separate iris and ciliary body melanomas were noted. This case demonstrates the usefulness of fine needle aspiration biopsy for both diagnosis and optimum therapy in selected cases.
