Abstract

Objectives: To explore the effect of exercise on intraocular pressure in non-diabetic non- hypertensive people.

Methods: A total of 5,516 subjects were divided into regular (≥ 3 days/week), occasional (1-2 days/week), and non-exercise groups according to exercise status defined as at least 20 minutes of vigorous physical activity per day during the previous six months. The intraocular pressure was measured on the center of cornea for three consecutive times, and the mean value for each eye was calculated. Multiple linear regression was used to investigate the relationship between intraocular pressure and habitual exercise, with adjustments for sex, age, general obesity, habits of smoking, coffee consumption, alcohol drinking and the presence of metabolic syndrome.

Results: The mean intraocular pressure was 15.16±2.66 mmHg, 15.47±2.74 mmHg, and 15.43±2.60 mmHg in subjects with regular, occasional and non-exercise habits. Subjects with regular exercise habits had a lower intraocular pressure than subjects with both occasional and non-exercise habits. Based on multiple linear regression analysis, regular exercise v.s. non- exercise and age ≥ 65 years v.s. <40 years were inversely associated with intraocular pressure. Male gender, general obesity and metabolic syndrome were independently associated with intraocular pressure.

Conclusion: Regular exercise is associated with a lower intraocular pressure in non-diabetic non- hypertensive people.
