Brimonidine 0.2% Versus Brimonidine Purite 0.15%: Prophylactic Effect on IOP Elevation After Nd:YAG Laser Posterior Capsulotomy

Abstract

Brimonidine 0.2% and brimonidine Purite 0.15% have similar efficacy in the prevention of IOP elevation after Nd:YAG laser posterior capsulotomy.

Fixed Combination Brimonidine–Timolol Versus Brimonidine for Treatment of Intraocular Pressure Elevation After Neodymium:YAG Laser Posterior Capsulotomy

“…IOP elevations of ‡ 5 mmHg occurred in 7.3% of patients, and IOP elevations of ‡ 10 mmHg occurred in 2.4% of patients treated with brimonidine. In another study, Yeom et al 27 have demonstrated that brimonidine 0.2% and brimonidine purite 0.15% had a similar efficacy for prevention of IOP elevation after Nd:YAG laser posterior capsulotomy. IOP elevations of ‡ 5 mmHg were observed in 5.7% of patients and elevations of IOP ‡ 10 mmHg were observed in 2.9% of patients treated with brimonidine.…”

Evaluation of the impact of Nd:YAG laser posterior capsulotomy on ocular pulse amplitude and anterior segment morphology

“…Since we instilled one drop of brimonidine 0.15%, 30 minutes preoperatively to all the eyes, we did not observe IOP rise in any patients. It was shown that pre‐operative topical brimonidine administration prevents acute IOP rise after the laser capsulotomy . We used low cumulative energy amounts during laser sessions and this would have an impact on the low IOP levels after the capsulotomy.…”

Use of topical brimonidine to prevent intraocular pressure elevations following Nd: YAG-laser posterior capsulotomy

“…[1213] In a study by Gartaganis et al ., a significant mean percent reduction in IOP was found after 0.2% brimonidine instillation 1 h pre capsulotomy and immediately post capsulotomy. However in the present study, when one drop of 0.2% brimonidine was instilled 1 hour pre-capsulotomy and immediately after Nd-YAG laser capsulotomy, IOP elevations were prevented.…”
