[Ring iris melanoma].
We are presenting a case of diffuse (ring) iris melanoma with secondary glaucoma, together with the differential diagnosis issues. The tumor extension and the high IOP imposed the enucleation of an eye that still had a good visual acuity. The pathology confirmed the diagnosis and showed the extension to the anterior chamber angle and the ciliary processes. The prognosis in this rare type of uveal melanoma is worse than in other iris melanomas.
