RETROSPECTIVE EVALUATION OF CYCLOPHOTOCOAGULATION PROCEDURE IN NEOVASCULAR GLAUCOMA

Introdução

The purpose of this study was to evaluate the efficacy and safety of cyclophotocoagulation in patients with neovascular glaucoma.

Métodos

Retrospective analysis of data from the electronic medical record of patients who were treated with cyclophotocoagulation for neovascular glaucoma during the year 2022 with a six-month follow-up was performed. Data regarding the etiology of neovascular glaucoma, the previous use of acetazolamide, the number of ocular hypotensors and intraocular pressure before and after the procedure were assessed. The Graph Pad Prism Version 8.0.1 was used for statistical analysis.

Resultados

A total of 66 eyes of 64 patients who were treated with cyclophotocoagulation for neovascular glaucoma during 2022 were included in this study. There were 35 (53.05%) cases of proliferative diabetic retinopathy and 26 (39.39%) cases of central retinal vein occlusion. During six months, three (4.54%) eyes lost post-operative follow-up. Among the cases that completed the follow-up, the mean initial intraocular pressure was 38.46 (± 12.28) mmHg and the initial number of ocular hypotensors was 2.19 (±0.61). A total of 48 (76.19%) patients were using acetazolamide before cyclophotocoagulation. The mean intraocular pressure was 24.91 (± 11.94) mmHg at the thirtieth postoperative day (p < 0.0001) and 17.14 (± 11.44) mmHg after six months of the surgery (p < 0.0001). Cyclophotocoagulation was indicated again in 20 (31.74%) eyes. After six months of follow-up, the number of ocular hypotensors was 1.60 (± 1.28) (p = 0.0144). Regarding safety, seven eyes had an initial visual acuity of no light perception. Among the remaining eyes, 21 (37.53%) of them evolved with no light perception visual acuity. No eye evolved to phthisis bulbi.

Conclusões

Although transcleral cyclophotocoagulation is a well-known option for treating advanced glaucoma, its efficacy was insufficient in several eyes in our study, leading to procedure repetition. Beyond that, many eyes evolved to no light perception visual acuity, which could have been influenced by the initial severity of the neovascular glaucoma.
