[Formalization of the process of differential diagnosis of nevi and initial choroid melanomas with the aid of a diagnostic table].

Basing on the results of a multidimensional discriminant computer-aided analysis of clinical findings in 11 patients with nevi and 102 with initial choroidal Stages TIa-TIb melanomas, the authors suggest formalization of the process of differential diagnosis between nevi and initial choroidal melanomas. For this purpose a diagnostic table with the minimal number of signs was developed. The disease can be diagnosed (the share of erroneous diagnoses is under 6 percent) with the use of just common instruments that can be found in any ophthalmology room.
