Researchers from the University of California, San Diego found that virtual reality is useful for measuring balance in patients with glaucoma.
Falls are the leading cause of injury-related death among older adults, and patients with glaucoma are three times more likely to fall than anyone else. Yet, few tools exist to properly assess balance.
In a study involving 42 patients with glaucoma and 38 healthy subjects, researchers used the Oculus Rift stereoscopic glasses. The headset can simulate various situations when worn on a special platform designed to measure balance and movement. The researchers simulated moving through tunnels and spinning floors.
During these simulations, participants with glaucoma had to make a pronounced effort to regain their balance 30% to 40% more than those without glaucoma, demonstrating greater difficulty keeping their balance. People with a history of falling had the most difficulty.
This type of tool could be used to quickly identify patients most at risk for falling and to take preventive measures.
