[Bilateral diffuse uveal melanocytic proliferation : a rare paraneoplasic syndrome to be diagnosed early].

Diffuse bilateral uveal melanocytic proliferation is a rare paraneoplastic ophthalmologic syndrome. The increase in life expectancy in oncology partly explains the gradual increase in its incidence. In almost half of the cases, the syndrome manifests itself before the diagnosis of primary neoplasia. It should be suspected in cases of bilateral uveal pigmented lesions that do not meet the clinical criteria for other known eye pathologies. Legal blindness occurs for the majority of patients during the first year after the initial clinical presentation. Death, due to the severity of the underlying pathology, occurs statistically within three years. Here we display the case of such a diffuse bilateral uveal melanocytic proliferation in a patient with relapsed colonic adenocarcinoma, initially treated for age-related macular degeneration.
