Rev Bras Oftalmol. 2015; 74 (6): 400-3 RESUMOO melanocitoma do disco óptico é um tumor benigno, com pouca predisposição a transformação maligna para melanoma. Geralmente é assintomático, contudo deve ser avaliado periodicamente com exames, sendo um deles a campimetria computadorizada que se encontra alterada em 90% dos casos. Relatamos o caso de um homem de 61 anos sem diagnóstico prévio de melanocitoma do disco óptico. Discute-se a importância de um diagnóstico diferencial com melanoma e acompanhamento seriado do paciente.Descritores: Disco óptico/patologia; Neoplasias do nervo óptico/complicações; Melanoma/diagnóstico; Diagnóstico diferencial; Diagnóstico por imagem; Relatos de casos ABSTRACTThe optic disc melanocytoma is a benign tumor, with little predisposition to become a melanoma.
