采用目测法对２４３例心血管内科住院患者的角膜类脂环（角膜环）进行了观察，结果角膜环的发生率根据年龄分组，＜５０岁者为２５％，５０岁～者为７７．８％，６０岁以上者均＞９５％；根据血压水平分组，高血压者为９０．６％，血压正常者为７７．６％，提示角膜环的发生与年龄、血压有关（Ｐ＜０．０５）。本资料还提示，其发生与疾病种类有一定关系，与血脂、血糖、体态及性别等因素无关。 The corneal alveolar rings (corneal rings) of 243 cardiovascular inpatients were observed by visual inspection. The results showed that the incidence of corneal ring was grouped according to age, with 25% of patients <50 years old and 77.8% of patients aged 50 years %, Those over 60 years old were> 95%. According to the level of blood pressure, hypertension was 90.6% and normotensives was 77.6%, suggesting that the occurrence of corneal ring was related to age and blood pressure (P <0.05 ). The information also suggests that its occurrence and disease types have a certain relationship, and blood lipids, blood glucose, body and gender and other factors.
