Abstract:
Objective:To investigate the impacts of carteolol hydrochloride combined with brinzolamide on intraocular pressure, retinal nerve fiber layer (RNFL) thickness and ocular blood flow parameters in patients with glaucoma.Methods:A retrospective analysis was conducted on the clinical data of 80 glaucoma patients diagnosed and treated in Zhoushan Hospital of Zhejiang Province from January 2019 to January 2022. The patients were divided into the control group (40 patients, treated with carteolol hydrochloride) and the study group (40 patients, treated with brinzolamide combined with carteolol hydrochloride). The therapeutic effect, intraocular pressure, RNFL thickness, blood flow parameters of ocular blood vessels and adverse reaction rate were compared between the two groups.Results:The total effective rate of the study group was significantly higher than that of the control group: 95.00% (38/40) vs. 75.00% (30/40), and the difference was statistically significant ( P<0.05). Before treatment, the intraocular pressure, RNFL thickness, peak systolic blood flow velocity (PSV), end diastolic volume (EDV), resistance index (RI) levels in the two groups were not obviously different ( P>0.05); after treatment, the intraocular pressure: (19.79 ± 3.92) mmHg (1 mmHg = 0.133 kPa) vs. (25.17 ± 4.43) mmHg, (13.47 ± 2.56) mmHg vs. (25.25 ± 4.51) mmHg, and RI levels of both groups of patients were significantly reduced: 0.39 ± 0.07 vs. 0.47 ± 0.08, 0.34 ± 0.06 vs. 0.46 ± 0.07 ( P<0.05), while PSV and EDV were significantly increased: (13.75 ± 3.08) cm/s vs. (12.41 ± 2.80) cm/s, (15.32 ± 3.33) cm/s vs. (12.35 ± 2.79) cm/s and (7.92 ± 1.67) cm/s vs. (6.67 ± 1.25) cm/s, (8.86 ± 1.81) cm/s vs.(6.72 ± 1.29) cm/s ( P<0.05). The changes in the study group were more significant than those in the control group ( P<0.05), and the RNFL thickness of the study group patients was significantly increased: (73.72 ± 12.57) μm vs. (69.91 ± 10.42) μm ( P<0.05). There was no obvious difference in the total incidence of adverse reactions between the two groups ( P>0.05). Conclusions:The combination of carteolol hydrochloride and brinzolamide has an obvious therapeutic effect on patients with glaucoma. It can reduce the intraocular pressure of patients, increase the thickness of RNFL, improve the blood flow status of eye vessels, and has good safety. It is worth popularizing in clinic.
