RESUMO
To evaluated the correlation between intracranial pressure [ICP] and intraocular pressure [IOP]. This interventional case series included 90 patients undergoing lumbar puncture [LP] for neurologist evaluation. IOP was measured before and 1 hour after the LP by using Goldmann tonometer. Patients were compared into two groups: patients with normal ICP [<20 cmH2O] and patients with high ICP [>/=20 cmH2O]. Patients included 29 male and 61 female subjects with mean age of 32.9 +/- 11.4 [range 13-62] years. Thirty-three patients had normal ICP and 57 patients had high ICP. There was a significant correlation between ICP and IOP such that 71.9% of the high ICP group had high IOP [>/=21 mmHg] and 28.1% of them had normal IOP [P<0.001]. Significant decrease in IOP occurred after LP in the high ICP group [P< 0.001]. It seems that there is a significant correlation between IOP and ICP
