Abstract

PURPOSE
To investigate the efficacy of anterior chamber paracentesis in intravitreal triamcinolone acetonide injection (IVTA). METHODS: A prospective, randomized clinical trial was conducted on 30 eyes of 30 patients undergoing IVTA. Eyes were randomly divided into two groups, those which had undergone anterior chamber paracentesis (Group 1, 15 eyes) and those which had not (Group 2, 15 eyes). We analyzed postoperative changes in intraocular pressure (IOP) in each group. RESULTS: In group 1, the mean preoperative IOP was 15.33+/-1.72 mmHg; postoperative IOP at 2 and 15 minutes was 7.80+/-1.47 and 11.73+/-1.67 mmHg, respectively. In group 2, there was significant elevation of IOP (46.73+/-8.26 mmHg) 2 minutes after the injection, although this was reduced to the normal range (16.13+/-2.61 mmHg) within 15 minutes. CONCLUSIONS: Routine anterior chamber paracentesis seems to be inappropriate considering the brief elevation in IOP that immediately follows IVTA.
