[Use of antiglaucoma therapy to reduce acute intraocular pressure rise following neodymium: YAG laser iridotomy in angle-closure glaucoma patients].

AIM: To evaluate the efficacy of topical antiglaucoma therapy in reducing acute intraocular pressure (IOP) elevation after neodymium: Yag laser iridotomy.

PATIENTS AND

METHODS

Primary angle-closure glaucoma (PACG) eyes were randomized to receive premedication with latanoprost and pilocarpine, brimonidine 0.2% and pilocarpine or only with pilocarpine before Yag laser iridotomy. Postoperative IOP changes were compared with Wilcoxon signed-ranks test using the fellow eyes in each group.

RESULTS

Postoperative pressure spikes were significantly lower in the groups of patients with local antiglaucoma therapy with pilocarpine than in the control group. Mean elevation of IOP was less in the groups of patients with local antiglaucoma therapy with pilocarpine at 2 hours postoperatively.

CONCLUSION

Local antiglaucoma therapy may reduce the acute IOP rise following Yag laser iridotomy in PACG eyes.
