Nomogram using example 2: patient extracted from the database of the photodynamic therapy (PDT) experience. This patient had diabetes, a tumor thickness of 2.79 mm, tumor volume of 0.22 ml, and tumor distance to fovea of 3.83 mm before neoadjuvant PDT. After PDT, a reduction of tumor thickness (from 2.79 mm to 2.25 mm) and volume (from 0.22 ml to 0.12 ml) were observed. The nomogram shows a probability decrease to develop maculopathy from 86% to 74% in the patient in exam. Patient’s characteristics before PDT are indicated with solid line and after PDT with dashed line
