Abstract
Objective We evaluated the correlation between intracranial (ICP) and intraocular pressure (IOP). Methods 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. Results 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. Interpretation IOP is correlated with ICP. Ann Neurol 2006;59:867–870
