Pseudotumor Cerebri Clinical Trial
Official title:
Assessment of Pupillary Response and Visual Field Defects by Objective Multifocal Chromatic Pupillometer in Patients With Pseudotumor Cerebri and Healthy Subjects
PTC(Pseudotumor cerebri) patients may develop increased Intracranial pressure (ICP) that can produces increased pressure around the distal optic nerve,which is likely followed by venule compression, ischemia, and loss of visual function.Vision loss in PTC is most commonly characterized by standard automated perimetry to measure peripheral visual field sensitivity. Pupillometry is a promising approach for functional assessment in PTC because it is noninvasive, objective, performed quickly with minimal patient cooperation needed. The feasibility of using chromatic multifocal pupillometry for assesment of PTC will be examined.
