Summary

The purpose of this study is to evaluate the diagnostic value of central retinal artery Doppler study in case of increased intracranial pressure.

Conditions

  • Increased Intracranial Pressure

Interventions

RADIATION

doppler study of central retinal artery

pulsed wave Doppler after decreasing the sample volume to fit inside the center of CRA. We will measure the peak systolic velocity (PSV), end diastolic velocity (EDV), and the resistivity index which equal PSV-EDV/PSV, we will measure 3 times and the expected normal value is less than 0.7.
