Table 3. Logistic regression analysis showing the image properties of Optomap images [fundus autofluorescence (FAF), lesion touching optic disc, subretinal fluid, green laser separation image, transversal and longitudinal diameter in individual optic disc size] as variables with their contribution to successfully differentiate a melanoma from a nevus.
