The perception of self-motion is important for knowing where we are in an environment. This study shows that this perception may be adversely affected in AMD and glaucoma. Up to 74% of patients with these diseases will perceive visually-mediated self-motion at a different speed to normal and may also notice people or vehicles moving differently. Patients may compensate for this altered perception by moving at a different speed leading to a mismatch in sensory information. This may lead to increased accidents and falls. This study also shows that these patients may experience lower levels of severity of cybersickness (motion sickness-like symptoms associated with simulators and screens) with virtual reality (VR). As such, VR may be a useful tool for mobility rehabilitation. To read more: tinyurl.com/52oq57yn
