Cerebrospinal Fluid Pressure Decreases with Older Age

Abstract

There is a sustained and significant reduction of CSFP with age that begins in the 6(th) decade. CSFP is consistently lower in females. BMI is positively and independently associated with CSFP in all age groups. The age where CSFP begins to decline coincides with the age where the prevalence of POAG increases. These data support the hypothesis that reduced CSFP may be a risk factor for POAG and may provide an explanation for the mechanism that underlies the age-related increase in the prevalence of POAG and NTG.
