视网膜分枝静脉阻塞与视网膜中央静脉阻塞多发生于老年人,许多眼部和全身疾病如高血压、糖尿病、全身血管性疾病、高脂血症和开角型青光眼均能引起视网膜分枝静脉和中央静脉阻塞。作者对这些疾病的发病学进行了研究。(一)对象和方法:作者对1978～1986年美国Boston视网膜学会诊断为视网膜中央静脉阻塞或视网膜分枝静脉阻塞的479例中,资料完整的视网膜分枝静脉阻塞为214例,视网膜中央静脉阻塞为145例,并对其进行了分析。检查有无近视、高血压、高眼压、高血沉、结核菌素皮肤试验阳性、糖尿病、缺血性心血管疾病、胶原血管疾病、慢性阻塞性肺疾患、血胆
Retinal branch vein occlusion and central retinal vein occlusion occur in the elderly and many ocular and systemic diseases such as hypertension, diabetes, systemic vascular disease, hyperlipidemia and open angle glaucoma can cause retinal vein branch and Central venous obstruction. The authors studied the pathogenesis of these diseases. (A) of the objects and methods: The author from 1978 to 1986 the Boston Eye Society of the United States diagnosed as central retinal vein occlusion or retinal vein branch occlusion in 479 cases, the data intact retinal branch vein occlusion was 214 cases, the central retinal vein occlusion 145 cases, and analyzed. Check for myopia, high blood pressure, ocular hypertension, hypercoagulable, tuberculin skin test positive, diabetes, ischemic cardiovascular disease, collagen vascular disease, chronic obstructive pulmonary disease, blood gall
