Abstract
PURPOSE: To investigate the intraocular pressure (IOP)-lowering efficacy and tolerance of brinzolamide/brimonidine fixed combination (BBFC) under real-life conditions in a tertiary glaucoma centre. METHODS: Medical records of all ocular hypertensive and open-angle glaucoma patients (n = 52) treated with BBFC were retrospectively analysed. RESULTS: Thirty-nine patients had primary open-angle, 6 exfoliative, 2 pigment, 1 normal tension and 1 juvenile open-angle glaucoma and 3 ocular hypertension. The prior therapy was a prostaglandin analogue (PG) (n = 4), PG/timolol (n = 20), PG/timolol and topical carbonic anhydrase inhibitor (CAI; n = 19), timolol/CAI (n = 1), PG and CAI (n = 4), timolol/pilocarpine and PG (n = 1), timolol/brimonidine and PG (n = 1) and timolol/brimonidine, PG and CAI (n = 2). These were simplified to PG/timolol and BBFC (n = 41), PG and BBFC (n = 9), timolol and BBFC (n = 1) and timolol/pilocarpine, PG and BBFC (n = 1). The IOP on the study eyes was 21.2 ± 3.7 mmHg before and 16.9 ± 2.6, 16.0 ± 2.2, 17.6 ± 3.1 and 18.0 ± 3.1 mmHg after the introduction of BBFC at month 1, 3, 6 and 12, respectively (p < 0.0003 for all time points compared to baseline, p = 1.0 for all other comparisons). Thirty-one patients (59.6%) experienced no adverse event, 17 (32.7%) reported ocular and 6 (11.5%) systemic adverse events. BBFC therapy was terminated on 27 patients (51.9%): on 19 (36.5%) due to adverse events and on 8 (15.4%) due to insufficient IOP reduction. CONCLUSION: In real-life practice, the introduction of BBCF allows significant and clinically meaningful IOP reduction and therapy simplification in glaucoma patients requiring complex medication, but in more than one third of the patients it is not tolerated due to adverse events.
