Questions were asked to confirm if a specific side effect had been experienced, and then a numerical comparison between the two types of eye drop was made.Results: Thirty-one consecutive patients (12 males and 19 females aged 41–89 years) successfully completed the questionnaire. Comparison of the severity and chronicity of the side effects of the two types of fixed-combination eye drops showed that brinzolamide-timolol caused significantly less stinging for a shorter amount of time than dorzolamide-timolol; it also produced less eye redness for a significantly shorter amount of time. Brinzolamide-timolol produced more blurring, although the length of time this was present was similar to that for dorzolamide-timolol. No differences between the two eye drops were found for taste, overall impression, and likelihood of compliance.Conclusion: Our study confirms the findings of other researchers pertaining to the side effect profile of brinzolamide-timolol after switching from dorzolamide-timolol, which is a reduction in stinging but an increase in blurred vision. The advantage of one eye drop over the other then becomes patient-specific, depending on which side effect they find most tolerable. We suggest that both eye drops are acceptable choices in treating patients with glaucoma, and are interchangeable if compliance becomes an issue because of a specific side effect of one eye drop or the other.Keywords: Azarga™, Cosopt®, brinzolamide, dorzolamide, timolol, side effectsAuger GARaynor MLongstaff SDove Medical PressarticleOphthalmologyRE1-994ENClinical Ophthalmology, Vol 2012, Iss default, Pp 2059-2062 (2012) |
