Does physical fitness influence intraocular pressure?
The effects of physical fitness on intraocular pressure, was studied. The study was conducted in two parts. Part 1 consisted of three groups of physically fit subjects, each consisting of 50 subjects. In Part 2 subjects were categorized into control and experimental groups, each consisting of 16 subjects. The experimental group took a supervised exercise programme of three months. Intraocular pressure was measured with the Goldman applanation tonometer. As compared to sedentary subjects, intraocular pressures were lower in those who did moderate or severe exercises. In part one, the difference between group 1 consisting of sedentary and group 3 of physically fit subjects was 1.38 +/- 0.08 mmHg, (p < 0.001). In part two of this study, after exercise training the experimental group showed a marked increase in their physical fitness. The first difference between control and experimental groups was 0.13 +/- 0.27 mmHg (p > 0.05). After three months, this difference increased to 0.93 +/- 0.28 mmHg (p < 0.01). This study concludes that physical fitness reduces intraocular pressure. It would seem reasonable at present not to discourage patients who have glaucoma from light exercise, perhaps, on the contrary, it should be encouraged.
