Randomized Controlled Trial Comparative Study Clinical TrialApraclonidine 0.5% versus brimonidine 0.2% for the control of intraocular pressure elevation following anterior segment laser procedures.
Both apraclonidine hydrochloride 0.5% and brimonidine tartrate 0.5% are potent alpha-2 agonists, effective in controlling the intraocular pressure (IOP) rise following argon laser trabeculoplasty (ALT). Brimonidine has recently become available commercially as a 0.2% solution. Our goal in this study was to compare the efficacy and side effect profile of 0.2% brimonidine to that of 0.5% apraclonidine in the prevention of IOP spikes following anterior segment laser procedures. ⋯ Both drugs are highly effective in controlling IOP spikes following anterior segment laser procedures. There is a tendency toward higher risk of IOP rise following argon laser trabeculoplasty with 0.2% brimonidine as compared to 0.5% apraclonidine, however, this was not statistically significant.
