Abstract

Relevance: сurrently, micropulse transscleral cyclophotocoagulation is widely used for the treatment of refractory glaucoma. It has a high safety profile and can be applied to eyes with high visual potential. Continuous-wave cyclophotocoagulation has a more pronounced hypotensive effect; however, it is accompanied by a significant number of complications. During transscleral cyclophotocoagulation, it is suggested to use a standard position for the sensor, though the position of the ciliary processes may vary.

Purpose: to analyze the effectiveness and safety of the combined cyclophotocoagulation technique using transillumination.

Materials and Methods: the study included 22 patients (22 eyes) who underwent combined cyclophotocoagulation with transillumination. The observation period was 6 months, with control examinations conducted at 1, 3, and 6 months. At each visit, refractokeratometry, visual acuity assessment, ultrasound examination (B-scan), tonometry using the Maklakov method were performed. There was one case of postoperative uveitis in the form of iridocyclitis.

Results: after six months, intraocular pressure decreased by 45% from the baseline level-from 35.5 (34–38.5) mm Hg to 20 (20–21) mm Hg. The number of hypotensive therapy drops was also reduced-from 7 (5.75–7) to 4 (3.25–4) drops per day.

Conclusion: combined cyclophotocoagulation with transscleral transillumination demonstrated a stable hypotensive effect over 6 months, with no significant complications such as prolonged hypotony, phthisis bulbi, or persistent refractory uveitis, which are commonly seen with continuous-wave cyclophotocoagulation. Thus, this technique may become an effective alternative to standard methods of cyclophotocoagulation.

Keywords: glaucoma, cyclophotocoagulation, transillumination.
