Purpose The aim of the study was to evaluate intraocular pressure (IOP) before and after moderate exercise in normal healthy individuals with defined physical exertion. The second aim of this investigation was to determine the correlation between resting IOP (IOP r) and its change induced by exercise as well as the relationship between resting heart rate (HR r) and changes in IOP after exercise.

Methods Forty-one healthy volunteers between the ages of 19 and 25 years were recruited for the study. First, the resting (reference) values IOP r and HR r were measured after 30 min of resting time. Volunteers consequently performed 30 min of exercise on a bicycle ergometer. Intraocular pressure was remeasured immediately after the end of exercise (the relevant IOP change was denoted as ΔIOP 0) and subsequently repeated 5, 10, 20, and 30 min after exercise.

Results A significant decrease in IOP compared with the resting value (post hoc Tukey honest significant difference test) was found immediately after exercise (p = 2 × 10−5) and 5 and 10 min after exercise (p = 2 × 10−5 and p = 3 × 10−5). Significant relationships were found between the change in IOP (ΔIOP 0) and baseline IOP (IOP r) and between the baseline resting heart rate (HR r) and the change in IOP (ΔIOP 0).

Conclusions There was a significant IOP-lowering effect, which was persistent for 10 min after 30 min of exercise. The IOP change was dependent on the initial IOP reading and initial HR.
