The GRADE Randomized Trial: Glaucoma Rehabilitation With Action viDeo Games and Exercise
Falls are one of the most serious public health concerns for seniors, with significant medical and economic consequences. This concern is even higher in patients with peripheral field loss due to glaucoma because of the patients' compromised visual input. The investigators' project proposes an innovative, entertaining, easily accessible and enjoyable intervention for improving mobility and postural control function in glaucoma patients with peripheral vision loss, who are more prone to falls and suffer from fear of falling. The new intervention examined in this project can be implemented in current vision and balance rehabilitation programs, and may benefit patients with different types of visual impairment to minimize their risk of falls and improve their quality of life.
• Presence of moderate to severe bilateral glaucomatous optic neuropathy (GON) from primary open-angle (including normal tension) or angle-closure glaucoma, as determined by an ophthalmologist, with abnormal Glaucoma Hemifield Test on standard Humphrey Field Analyzer 24-2 testing and matching nerve-fiber layer thinning on optical coherence tomography;
• Stable vision and visual field loss for at least 3 months;
• With a best-corrected distance acuity of 6/12 or better (equivalent to 0.3 logMAR acuity or better to confirm that participant's central vision is preserved);
• With a cognitive functional score of 22 or above in the Montreal Cognitive Assessment - Hong Kong version (to confirm participants' intact cognitive function).
