The relation between intracranial and intraocular pressures: Study of 50 patients


  • The study was performed at Imam General Hospital and Shariati General Hospital affiliated with Tehran University of Medical Sciences, Tehran, Iran. The study was first presented at the 13th Meeting of the European Neurological Society, Istanbul, Turkey, June 14–18, 2003.



We evaluated the correlation between intracranial (ICP) and intraocular pressure (IOP).


Of the 77 patients who underwent a lumbar puncture, 27 were excluded secondary to a history of glaucoma, using drugs effective on IOP, and abnormal funduscopic examination. ICP was measured by lumbar puncture. IOP was measured by two scales of Schiotz tonometer in both eyes, and the mean was calculated.


We found a significant correlation between ICP and mean IOP (p < 0.001; r = 0.955). Body mass index, age, and disease type had no significant effect on this correlation.
