Using eye imaging to measure pressure around the brain

Doctors need accurate ways to measure pressure around the brain, which can rise dangerously in conditions like severe headaches, brain bleeds, and brain tumors. This study is testing whether special eye imaging and photographs can detect these pressure changes without invasive procedures. The researchers believe that looking at blood vessels in the back of the eye may reveal when brain pressure is too high.

Currently, doctors must use painful procedures like spinal taps or surgical monitoring to measure brain pressure, and these carry risks of infection, bleeding, and nerve damage. This trial seeks to develop a safe, non-invasive way to detect dangerous brain pressure using only eye imaging, which could spare patients from these risky procedures.
