Optic Nerve Head Quantification While Reducing Elevated Intracranial Pressure

NCT02558309 · Status: WITHDRAWN · Type: OBSERVATIONAL

Last updated 2017-01-12

No results posted yet for this study

Summary

The goal of this study is to examine in-vivo the effect of intraocular (IOP) and intracranial pressures (ICP) on the optic nerve head (ONH). The effect of ICP on eye health has been an area of concrete research effort in recent years. The ability to acquire non-invasive and highly detailed information on both the eye and the brain using technologies such as magnetic resonance imaging (MRI) and optical coherence tomography (OCT) have paved the way to assess non-invasively the effect of ICP in-vivo. In this study, we will quantify the structural changes in the ONH in subjects with elevated ICP while they are treated to reduce the elevated pressure. This process will occur in a stepwise fashion over a period of time determined by the clinical treatment plans. We will apply controlled pressures to the eye during each step of ICP lowering while OCT images are obtained.
