Первые результаты микроимпульсной циклофотокоагуляции при вторичной глаукоме у пациентов после витреоретинальной хирургии с использованием силиконового масла

Abstract

Quite often, the use of silicone oil (SO) in routine vitrectomy can lead to increased IOP. Silicone-induced glaucoma is classified as refractory. It is difficult to treat with hypotensive drops or surgical treatment. The introduction of MicroPulse cyclophotocoagulation (MP-CPC) significantly contributed to reducing the number of side effects of laser operations by reducing the operating cycle to 31.3 %. Purpose. To analyze the first results of MP-CPC for secondary glaucoma that developed after vitrectomy using SO. Material and methods. A retrospective analysis of data from 22 patients was performed: 13 eyes were avitreal and 9 eyes had SO. IOP monitoring was carried out on first day, after 2 weeks, 1, 3 and 6 months. Results. On the first day after MP-CPC, a significant decrease in IOP was noted by 28 % compared to the baseline and averaged 19.2 ± 4.2 mmHg (p < 0.05). There was no statistically significant difference between the groups of patients with avitria and with SO. Over the next 3 months, the average IOP level after MP-CPC remained within the range of 19–21 mmHg. By the 6th month of observation, there was a tendency to increase IOP, which required to repeat MP-CPC. Conclusion. MP-CPC for secondary silicone-induced glaucoma that developed after vitrectomy has shown high efficiency and safety in patients with both avitria and the presence of silicone. Considering the compensation of IOP, which persists for up to 6 months after MP-CPC, it is possible to perform a repeat laser procedure without changing the hypotensive therapy regimen.
