摘要
高原视网膜病变是高原病的一种表现,病因及发病机制尚不明确,缺氧是最重要的发病因素.主要表现为视网膜出血,根据出血严重程度可分为四级.早期诊断并及时治疗,患者预后较好.高原视网膜病变重在预防,建议缓慢地上升高度及适当延长适应时间.同时注重高原病的其他病变,如急性高原反应、高原性肺水肿和高原性脑水肿.
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）.
