Purpose: to assess the efficacy of transpupillary thermotherapy (TTT) in treatment of the progressive choroidal nevus. Material and Methods. Diagnosis and treatment of 29 patients (29 eyes) with progressive choroidal nevus were analyzed. The follow-up was from 4 months to 3 years. In the diagnosis of the neoplasm we paid a special attention to the ultrasound B-scanning, optical coherence tomography (ОСТ), OCT-angiography. According to the ultrasound scanning (B-scanning) data the neoplasm height varied from 0.78 to 3.64 mm (1.60 (1.40; 1.84) before treatment, the length varied from 1.30 to 14.05 mm (6.41 (5.12; 7.54). For treatment we used laser device IRIS MEDICAL IQ 810 "IRIDEX" in the LONGPULSE mode. Results. After treatment the prominence in the nevus zone was not defined in 14 cases (48.3%) according to B-scanning data. In 15 (51.7%) patients the neoplasm height and length decreased: prominence height was 1.40 (1.20; 1.50), varying from 0.7 to 3.1 mm, the length was from 1.3 to 7.5 mm (6.10 (4.69; 7.30). In 28 (96.5%) patients visual acuity has not changed. Conclusion. The treatment of progressive choroidal nevus by TTT showed its efficacy, safety and good tolerance.
