Is ocular melanosis a risk factor for uveal melanoma?
['Ocular/oculodermal (oculo[dermal]) melanocytosis is a congenital periocular pigmentary condition that can lead to the development of uveal melanoma, estimated at 1 in 400 affected patients.', 'Melanosis oculi is often underestimated as a risk factor for uveal melanoma and glaucoma. Ophthalmic surveillance, every 6 or 12 months is important, in patients with ocular melanocytosis for early detection of high risk diseases.', ' One of about 400 patients with ODM followed for life is estimated to develop uveal melanoma. Excessive melanocytes in the uveal tract in ODM may provide the biologic basis for susceptibility to the development of uveal melanoma. Patients with ODM should be monitored ophthalmoscopically, especially during the susceptible period, for the development of uveal melanoma. The authors suggest that a national registry of ODM patients be created and prospective data collected to better assess the risk of developing uveal melanoma.', 'In the white population, an association between oculo(dermal) melanocytosis (ODM) and uveal melanoma is well recognized. ', 'Malignant melanomas may arise in the uveal tract, the conjunctiva, the skin of the eyelid, or the orbit. Risk factors so far identified include pre-existing choroidal naevi for uveal melanomas, primary acquired melanosis (PAM) for conjunctival tumours, and ocular and oculodermal melanocytosis for uveal and orbital lesions.
