Comparative study of the intraocular pressure fluctuations between the 24 hr tensional curve, Borrone test and water drinking test in patients with primary open glaucoma in Mexico

Abstract

Objetives: To evaluate de results of the water drinking test and Borrone test in patients with primary open angle glaucoma, comparing it with 24 hr tensional curve. Material and methods: To the same group of patients a 24 hr tensional curve was perfomed and the results were compared with the Borrone test and the water drinking test. Results: The average of intraocular pressure fluctuation was 4.05 ± 1.57 mmHg in the 24 hr tensional curve, for the water drinking test was 3.55 ± 1.5 mmHg and for Borrone test was 2.55 ± 2.83 mmHg. The difference of the results between the 24 hr tensional curve and Borrone test were statistically significant. The difference of the results between the 24 hr tensional curve and water drinking test were not statistically significant. We observed just a 40% of concordance between both the Borrone test and water drinking test with the 24 hr tensional curve. Conclusions: In the present study the Borrone test and the water drinking test obtained a low correlation with the 24 hr tensional curve which is considered the gold standard.
