RESUMO
PURPOSE: To study the frequency and nature of intraoperative and early postoperative complications after glaucoma surgeries depending on several factors. MATERIAL AND METHODS: 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. RESULTS: 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. CONCLUSION: 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.
