This paper presents the long-term results of single dose stereotactic radiosurgery for intraocular uveal malignant melanoma, and summarizes the results of the retrospective study in 170 Slovak patients. A group of uveal melanoma patients (149 choroidal melanoma, 21 ciliary body melanoma) from 20 to 92 years of age with 59 year median were treated in 2001-2016. There were 81males (47.7%) and 89 females 89 (52.3%). The median overall follow-up time was three years. The median tumor volume at baseline was 0.5 cm³ (ranging from 0.2 to 1.6 cm³). The therapeutic dose was 35.0 Gy by 99% of dose volume histogram. The survival after single dose stereotactic radiosurgery was 96% in one year, 93% in two years, 84% in five years, 80% in seven years and 52% in eleven years. Secondary enucleation was necessary for 22 patients because of secondary glaucoma complication. The enucleation free interval ranged from one to six years. The survival rates in five year intervals and necessity of secondary enucleation due to complications after single dose stereotactic radiosurgery is comparable to other techniques.
