Comparative study of cyclophotocoagulation (CPC) and cyclocryocoagulation (CCT) as primary surgical procedures in patients with open-angle glaucoma with regard to efficacy and complications.In this retrospective cohort study, 184 eyes of 112 patients in whom cyclodestructive surgery was performed as a primary surgical procedure were examined. CPC was performed on 133 eyes and CCT on 51 eyes. A standardised multiple measurement of intraocular pressure (IOP) was performed on all patients preoperatively and at the follow-up examination after an average of 5.5 (1.5-12) months. In addition, the best-corrected visual acuity and the number of antiglaucoma agents were recorded.On average, a reduction in IOP was observed after both of the cyclodestructive procedures (CPC: -1.55 ± 2.50 mmHg, p < 0.05; CCT: -2.33 ± 3.06 mmHg; p < 0.05). The average difference in IOP reduction between the two procedures (0.78 mmHg) proved to be statistically insignificant (p = 0.08). In contrast, greater patient age and higher preoperative IOP values were found to be highly significant influencing factors. In 45
