Subcyclo laser procedure results in patients with glaucoma

Abstract

Purpose. To analyse the results of subCyclo (subliminal transscleral cyclophotocoagulation) laser procedure for patients with glaucoma. Material and methods. The study included 50 eyes of 32 patients diagnosed with various subtypes of glaucoma for which we performed subliminal transscleral cyclophotocoagulation under retrobulbar anesthesia. After the procedure, all patients were advised to continue their antiglaucoma medication until further notice and we added a topical steroid for 2 weeks. The minimum follow-up period was 6 months. Results. The mean IOP (intraocular pressure) decreased from the preoperative value of 26.27 mmHg (±6.52) to 15.9 mmHg (±5.72) one day after the treatment. At 7 days, the average IOP was 13.72 mmHg (±4.31), 15.81 mmHg (±3.69) at 6 weeks, 15.94 mmHg (±5.66) at 3 months and 16.32 mmHg (±5.24) at 6 months. The second intervention was performed in 9 eyes due to poor IOP control after the first procedure, two eyes developed ocular hypertonia 6-8 hours after the procedure and one eye presented mydriasis after the procedure. Conclusions. Early results for this study showed that subCyclo laser procedure could determine a satisfactory decrease of the IOP with a low risk of complications.
