To study the frequency and nature of intraoperative and early postoperative complications after glaucoma surgeries depending on several factors.
The study retrospectively analyzed 87 outpatient records and case histories of patients with primary open-angle glaucoma (POAG). All subjects had undergone standard trabeculectomy. The indication for surgical treatment was deterioration of visual function associated with increased intraocular pressure (IOP). During the follow-up, an assessment was made of intraoperative and early postoperative complications, as well as factors leading to their development.
During the observation period, the most frequently developing complications were found to be ciliochoroidal detachment – in 22 (25.8%) patients, and hyphema – in 12 (13.8%). One of the reasons for these complications is a significant, sometimes critical change in intraocular pressure when cutting open the eye. Isolated intraocular hypotension without signs of ciliochoroidal detachment was detected in 15 (17.24%) patients. Postoperative hypertension was found in 18 (20.68%) patients. Scarring of the newly created outflow tracts of intraocular fluid was the obvious cause of ophthalmic hypertension in 5 patients. In 16 (18.4%) cases, pronounced vascularization was found at the site of surgical intervention.
The most significant factors that have a possible impact on the outcome of glaucoma surgery – specifically, its hypotensive effect – are: age, duration of local antihypertensive therapy, comorbid somatic pathology, and the initial IOP level.
