Changes in visual acuity in patients with malignant melanoma of the uvea treated with stereotactic radiosurgery

The goal was to assess the changes in visual acuity before and after 6 months of treatment, depending on the dose in risk structures (lens, optic nerve). This is a retrospective study of 19 patients group treated in 2011. The average age of the group was (57.3 ± 12.4) years (31-73 years). The analysis of the studied group did not demonstrate dependence of the tumour presence on gender. Higher prevalence of tumours was observed in the elderly population. Considered relationship of worse diagnosis with higher age (r = 0.39; p = 0.13) we could not prove to be significant due to the small group of patients. The median of melanoma volume was 0.77 cm³ (0.11 to 1.76 cubic centimetres). The mean dose applied to melanoma was 37.34 Gy (Gy 36.74 to 44.65).
