The diameters of the optic nerves in 54 patients with high intracranial pressure(ICP)were checked and measured with B type ultrasonic tomography and the relationship between thewidth of optic nerve and the optic papiliedema was studied. The results showed that the average diameter (6. 324-0.53)mm of the optic nerves in patients with high ICP was wider than that(3.61 ~:0.29 )mm in health subjects (P(0.01). The rate of increasing width of optic nerve (87.00%)was higher than that (67.00~)of papilledema (P(0.05). In addition,in 19 patients with ICP between 1.97 and 2.50 kPa, the rate of increasing width of optic nerve (79. 00~)was higher than that (42.00%)of papilledema (P (0. 05). These results indicated that measuring the diameter of optic nerve might be more practical than observing tile presence of papilledema in diagnosing high ICP,especially in early stage. （Chin J Ocul Fundus Dis,1996,12: 86-87）
