目的：探讨高海拔地区（2260m）缺氧因素对重度妊高征患者眼底视网膜影响的程度，并寻求综合救治的措施;方法;对重度长高征常规行检眼镜及裂隙灯显微镜检查眼底，根据视网膜病变程度分视网膜血管病变、视乳头高度水肿及网膜出血渗出、视网膜脱离等。并以积极地非手术综合措施进行治疗;结果：对高度妊高征205例检查后发现198例存在眼底小动脉痉挛及动静脉比例失调，严重视网膜病变102例，其中视乳头高度水肿混浊52例，视网膜出血和渗出38例，视网膜脱离12例，经积极综合治疗，101例患者视力逐渐恢复，眼底病变逐渐消失，治愈率为99.0％;结论：高海拔地区因缺氧因素对重度妊高征视网膜影响大于平原地区，视网膜病变发病率高、程度重，应引起高度重视并行常规检查，早期治断和积极的非手术综合治疗对减轻和减少视力永久性损害有重要意义。
Objective: To investigate the effect of hypoxia in high altitude (2260 m) on the fundus retina in patients with severe PIH and to find out the measures for its comprehensive treatment. Methods: The patients with severe hypercholesterolemia were examined by routine ophthalmoscope and slit lamp microscope. Degree of retinopathy retinal vascular disease, a high degree of edema and retinal hemorrhage exudate, retinal detachment and so on. Results: There were 198 cases of fundus arterioles spasm and arteriovenous malocclusion in 205 cases of high PIH, 102 cases of severe retinopathy, of which 52 cases were highly edema and opacity , Retinal hemorrhage and exudation in 38 cases, retinal detachment in 12 cases, the positive comprehensive treatment of 101 patients with visual acuity gradually recovered, retinal lesions gradually disappear, the cure rate was 99.0%; Conclusion: high altitude due to hypoxia on severe pregnancy-induced hypertension Retrospective retinal impact than the plain area, the high incidence of retinopathy, the degree of heavy, should pay close attention to parallel routine examination, early treatment and aggressive non-surgical comprehensive treatment to reduce and reduce permanent damage visual acuity is important.
