CYCLOCRYOCOAGULATION IN SECONDARY NEOVASCULAR GLAUCOMA AND OUR RESULTS.

Purpose: To retrospectively evaluate the use of cyclocryocoagulation (CCK) in secondary neovascular glaucomas performed at the Department of Ophthalmology, Faculty of Medicine, Charles University and University Hospital Hradec Králové in the years 2016-2019.

Material And Methods: In a retrospective study, 30 procedures of 26 eyes of 24 patients were evaluated. All patients underwent CCK surgery. The main entry criteria were the presence of secondary neovascular glaucoma in diabetes or on the basis of occlusion of the retinal artery or vein and subsequent dispensarization of the patient in the 1st and 6th month after the operation. The parameters evaluated were: the best-corrected visual acuity (BCVA), intraocular pressure value (IOP), data of pain and change in the number of active substances of antiglaucoma therapy.

Results: The mean age of patients at the time of the procedure was 62 years (range 22-85 years). The average number of procedures per eye was 1.15 out of a total of 30 procedures, 26 eyes were performed on 24 patients. The most common indication for CCK in secondary glaucoma-vascular complications in diabetes were in 21 procedures, vascular complications - after occlusion of the retinal vein or artery were in 9 cases. Two patients had both eyes operated on within one year. Three patients underwent two procedures on the same eye during the study period. One of them had two procedures on both eyes. The average value of the number of active substances of antiglaucoma drugs decreased from 3.10 to 2.87 after the 1st month (p = 0.318) and after 6 months it was 2.6 (p.
