Measuring Intracranial Pressure
Rochester, MN
The goal of this study is to evaluate the efficacy of B-scan ultrasonography in identifying increased ICP in patients with idiopathic intracranial hypertension via measurement of optic nerve sheath diameter.

Evaluating Raised Intracranial Pressure Using MR Elastography
Rochester, MN
Investigators will compare magnetic resonance (MR) elastography and/or ultrasound elastography measurements to other forms of noninvasive methods of detecting raised intracranial pressure, including optical coherence tomography (OCT) imaging measurements of the retinal nerve fiber layer (RNFL) and indirect signs of raised intracranial pressure on magnetic resonance imaging (MRI).

A Study to Evaluate Blood Chemistry, Genetics, and Eye Exams in Women with Polycystic Ovary Syndrome and/or Idiopathic Intracranial Hypertension
Rochester, MN
The purpose of this study is to evaluate the blood chemistry, genetics, and eye exams in women with polycystic ovary syndrome and/or intracranial hypertension. Similar studies are being completed with astronauts. The results may help us better understand the nature, and ultimately the treatment of polycystic ovary syndrome, intracranial hypertension, and astronaut eye and vision issues.
