Resumen

Purpose: To describe the outcomes of a combined technique (Cyclo Mix) in uncontrolled glaucoma cases. Materials and methods: Retrospective study. The Supra 810 nm subliminal laser (Quantel Medical, Cournon d’Auvergne, France) was used. A combined technique was performed using the subliminal mode (Subcyclo) in one hemifield (power of 2,000 mW, a duty cycle of 35%, and 80–150 seconds), and the continuous wave mode (Thermo Cyclo) on the other hemifield (power of 1,000 mW, exposure time of 2 seconds per spot). The primary endpoint was the probability of surgical failure. Mean intraocular pressure (IOP) change, best-corrected visual acuity (BCVA), number of glaucoma eye drops, and complications at 6 months postoperatively were secondary outcomes. Results: Twenty-three eyes from 13 patients were included. Mean age was 61.4 ± 16.7 (range: 18–78 years), and 69% were female, with a baseline IOP of 20.3 ± 5.9 (range: 13–38 mm Hg). The cumulative probability of failure was 18 and 22% on days 90 and 180, respectively. Mean IOP reduction was −25.6 ± 20.9% at 6 months. The number of glaucoma eye drops was reduced to 1.2 ± 1 (p = 0.0024) at 6 months. No statistically significant change in the mean BCVA compared with baseline at 6 months was found (p = 0.84), and no severe complications were reported. Conclusion: Cyclo Mix seems to be a safe therapy that effectively reduces the IOP and glaucoma medications in eyes with uncontrolled open-angle glaucoma for up to 6 months. © Jaypee Brothers Medical Publishers. 2020.
