Abstract :ABSTRACT Purpose: The aim of our study is to reveal the chronic effects of Valsalva maneuver (VM), whose acute effects on the eye are well known. Material Method: A total of 50 eyes from 25 patients and 60 eyes from 30 age-matched and gender-matched healthy individuals were included in this cross-sectional study. A complete ophthalmic examination was performed for all patients. The central corneal thickness, iridocorneal angle (ICA) and anterior chamber depth were performed with the corneal topography. The spectral-domain optical coherence tomography was used to evaluate choroidal thickness (CT) and retinal nerve fiber thickness. Results: There were 25 patient study group and 60 patient control group. Intraocular pressures were 18.31 (std 2.64) in the study group and 15.63 (std 2.14) in the control group, and this difference was statistically significant. (p <0.001) The ICA was found to be 40.30 (std 5.84) in the study group and 45.15 (std 5.51) in the control group, and this difference was statistically significant. (p = 0.001) The subfoveal CT was determined as 273.71 (std 39.35) in the study group and 256.71 (std 20.48) in the control group, and this difference was statistically significant. (p = 0.005) There was a mild positive correlation between duration and central CT. (p: 0.039, r: -0.288) Conclusion: This study is one of the first studies investigating the permanent effects of frequent repetitions of the VM. As a result, we found that IOP and CT increased and the ICA decreased in patients exposed to chronic VM.
