[Risk factors of small choroidal melanocytic lesions].

Purpose: To detect the possible predictive factors of tumor spread or future growth of the small choroidal melanocytic lesions.

Methods: Retrospective review of the clinical medical histories of fourteen patients with small choroidal melanocytic lesions --< or =3mm in thickness-, which due to these features could be confused with choroidal nevus. Few clinical parameters are assessed: tumor thickness, posterior tumor margin touching the optic disc, symptoms and documented tumor growth as main prognostic features.
