Abstract:

High-altitude retinopathy (HAR) is a manifestation of high altitude disease. Its etiology and pathogenesis is still not clear, and hypoxia is the most important factor. The predominant characteristic is retinal hemorrhage. According to the severity of hemorrhage, it can be divided into four levels. Early diagnosis and timely treatment critical for a good prognosis. The prevention is the key point for HAR. Rising altitude slowly and extending adaptation time properly are suggested. At the same time,  other high altitude diseases need to bear in mind are, such as acute mountain sickness(AMS), high-altitude pulmonary edema(HAPE) and high-altitude cerebral edema(HACE).   (Int Rev Ophthalmol,  2015,  39:     401-405)
