Useful Field of View Performance in the Intact Visual Field of Hemianopia Patients.

ABSTRACT: Purpose:Postchiasmatic brain damage commonly results in an area of reduced visual sensitivity or blindness in the contralesional hemifield. Previous studies have shown that the ipsilesional visual field can be impaired too. Here, we examine whether assessing visual functioning of the "intact" ipsilesional visual field can be useful to understand difficulties experienced by patients with visual field defects. Methods:We compared the performance of 14 patients on a customized version of the useful field of view test that presents stimuli in both hemifields but only assesses functioning of their intact visual half-field (iUFOV) with that of equivalent hemifield assessments in 17 age-matched healthy control participants. In addition, we mapped visual field sensitivity with the Humphrey Field A
