Abstract

Aims: To study the effect of axial length on the hypotensive effect of latanoprost in primary open angle glaucoma (POAG) in a prospective, observational study.

Methods: The authors measured axial length and baseline intraocular pressure (IOP) of 109 eyes with POAG, and then repeated the IOP measurements at 1, 3, and 6 months after starting treatment with latanoprost.

Results: The mean IOP level was significantly lower in eyes with a shorter axial length compared with the eyes with a longer axial length both at 3 and 6 months of treatment (p = 0.03 and p = 0.04, respectively, ANOVA).

Conclusion: The hypotensive effect resulting from treatment with latanoprost could be related to ocular axial length.
