Geographic Altitude, Ocular Diseases and Injuries

Various ocular disorders remain a major concern for medical care providers and health policy makers. Only in the US more than 6.6 million people were affected by blindness in 2011 (1). Meanwhile, even though people mostly inhabit low or moderate altitudes, about 140 million people worldwide live above 2500 meters (2). Therefore, association between various vision disorders and high altitude remains a significant health concern for millions of people throughout the world.
