Exercise as medicine: HIIT may slow glaucoma damage
NCT ID NCT06058598
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether high-intensity interval training (HIIT) can improve eye health and slow disease progression in people with glaucoma. 168 adults aged 40-75 with open-angle glaucoma will be randomly assigned to either a supervised HIIT program or standard care with lifestyle advice. The main goal is to see if exercise improves blood vessel function in the retina, which could help control the disease and enhance quality of life.

Inclusion Criteria: * Voluntary written informed consent of the participant has been obtained prior to any screening procedures * Patients with primary open angle glaucoma (POAG), high tension glaucoma (HTG) and normal tension glaucoma (NTG), aged 40 - 75 years * In regular follow-up in either of the two study centres Exclusion Criteria: * Patients having had glaucoma surgery within 6 months before start of the project * Patients with changes in topical medication or laser trabeculoplasty within 3 months before start of the project * Patients with very severe glaucoma (visual field mean deviation lower than -12Db) * Significant opacification of ocular media * Patients with life-threatening arrhythmia, signs of ischemia during CPET which preclude participation in an exercise trial * Patients with insulin treated diabetes, chronic obstructive pulmonary disease or cancer. * Patients doing ≥1 structured exercise training session per week or \>150min of exercise/week assessed via the following two questions: a. On average, how many days per week do you engage in moderate to vigorous physical activity (like brisk walking)? b. On average, how many minutes per day do you engage in physical activity at this level? Calculate the total weekly minutes of exercise by multiplying a times b. * Mental or physical limitation precluding participation in a high intensity exercise program
