Measurement of the optic nerve diameter by echographic technique has been performed in 40 patients with intracranial hypertension syndromes of various origin. In all the cases examined the diameter was always increased. Postoperative checks revealed a decrease of the nerve thickness until it reached the normal values. The changes in the optic nerve diameter reflect the variations of the intracranial pressure and they appear earlier than any changes in the fundus oculi. This simple and non-invasive echographic technique is very useful in following patients with an intracranial hypertension syndrome.
采用超声技术对40例不同病因的颅内高压综合征患者进行了视神经直径测量。在所有检查病例中，视神经直径均增大。术后检查显示神经厚度减小，直至达到正常值。视神经直径的变化反映了颅内压的变化，且比眼底的任何变化出现得更早。这种简单且无创的超声技术在跟踪颅内高压综合征患者方面非常有用。
