Diagnostic performance of pupil perimetry in detecting hemianopia under standard and virtual reality viewing conditions.

ABSTRACT:

Purpose

To determine the diagnostic performance and reliability of two pupil perimetry (PP) methods in homonymous hemianopia.

Methods

This cross-sectional monocenter cohort study performed gaze-contingent flicker PP (gcFPP) and a virtual reality version of gcFPP (VRgcFPP) twice on separate occasions in all patients suffering from homonymous hemianopia due to neurological impairment. The main outcomes were (1) test accuracy and (2) test-retest reliability: (1) was measured through area under the receiver operating characteristics curve (AUC) calculation of (VR)gcFPP results with comparators being SAP and healthy controls, respectively; (2) was evaluated by comparing tests 1 and 2 of both methods within patients.

Results

Both gcFPP and VRgcFPP were performed in 15 patie
