眼内压与颅内压有着密切的关系,眼结膜的微循环与脑的微循环同样有着密切的关系。通过对眼球结膜的观察来判断颅脑损伤的轻重,预测预后不失为一种简单、实用、有效的方法。笔者自1986～1993年对1 850例颅脑损伤患者的眼球结膜进行了观察,报告如下。临床资料凡颅脑损伤患者不论病情轻重,入院后都进行眼球结膜的观察。共观察1850例,其中男1342例,女508例。轻型颅脑损伤773例,中型747例,重型330例。眼外伤不作为统计对象。观察方法:采用10倍放大镜直接观察。将其分为5级:Ⅰ.正常,无水肿及干燥。Ⅱ.轻度水肿,眼球结膜稍增厚约0.3～0.5mm,湿润。Ⅲ.重度水肿,眼球结膜增厚约0.6～1.2mm,湿润。Ⅳ.轻度干燥,眼球结膜稍隆起,但不湿润,角膜不混浊。Ⅴ.重度干燥,眼球结膜明显干燥,无泪液分泌,角膜表层亦皱缩无光,窥视眼底不清。结果:正常1349例,全部存活。
Intraocular pressure and intracranial pressure are closely related, microcirculation of the conjunctiva and brain microcirculation also have a close relationship. Through the observation of the eye conjunctiva to determine the severity of brain injury, predicting the prognosis after all, is a simple, practical and effective method. The author from 1986 to 1993 on the 1 850 cases of brain injury in patients with conjunctiva were observed, the report is as follows. Where the clinical data of patients with craniocerebral injury, regardless of severity, admitted to the hospital after the observation of conjunctival. A total of 1850 cases were observed, including 1342 males and 508 females. 773 cases of mild craniocerebral injury, 747 cases of medium, 330 cases of heavy. Eye trauma is not as a statistical target. Observation method: direct observation with a magnifying glass 10 times. Divided into five levels: Ⅰ. Normal, no edema and dry. Ⅱ. Mild edema, conjunctival slightly thicken about 0.3 ~ 0.5mm, moist. Ⅲ. Severe edema, conjunctival thickening of about 0.6 ~ 1.2mm, moist. Ⅳ. Mild dry, slightly bulging eye conjunctiva, but not moist, corneal opacity. Ⅴ. Severe dry, eye conjunctiva significantly dry, no tear secretion, corneal surface also shriveled, peep eyes blurred. Results: The normal 1349 cases, all survived.
