AIM: The aim of the study was to analyze changes in intraocular pressure after Nd: YAG laser capsulotomy in pseudophakic patients with glaucoma. PATIENTS AND METHODS: Intraocular pressure was recorded before, and 1 and 3 hours after YAG laser capsulotomy in 69 pseudophakic patients with glaucoma. Twenty eight patients received no therapy before capsulotomy, 21 patients received topical brimonidine 0.2%, and 20 patients received topical dorzolamide 2% 1 hour before laser capsulotomy. All patients received topical tropicamide 1% and tetracaine 0.5%. Nd: YAG laser posterior capsulotomy was performed using inverted-U technique to make a 3-4 mm diameter capsulotomy. After capsulotomy, all eyes received topical fluorometholone for 10 days. RESULTS: A pressure rise was greater in patients without any therapy before YAG laser capsulotomy. Eight patients with glaucoma showed intraocular pressure rise of 5 mmHg, and 2 patients pressure rise of 10 mmHg after laser capsulotomy. A reduction of intraocular pressure rise was found in patients who received dorzolamide 2% or brimonidine 0.2%, only 1 patient in each group developed a pressure rise of 5 mmHg. In all patients a significant pressure rise developed within the first hour. DISCUSSION: It is difficult to compare different studies due to different techniques of cataract surgery and different intraocular lense material and design. Barnes showed that 6 of 29 (21%) developed a pressure rise of 5 mmHg, and 1 of 29 (3%) patients a pressure rise of 10 mmHg. In our study, 29% of patients had a pressure rise of ≥ 5 mmHg, and 7% of patients had a rise of ≥ 10 mmHg after laser capsulotomy. These results may be associated with a large proportion of extracapsular cataract extraction (71%) versus phacoemulsification (29%) in our patients. CONCLUSION: Pretreatment with dorzolamide 2% or brimonidine 0.2% reduce the intraocular pressure rise after Nd: YAG laser capsulotomy in pseudophakic patients with glaucoma. LA: Croatian
