Abstract

A method for isolating and quantifying impairments of a subject's gaze stabilization system is provided. A subject's static visual acuity is measured to arrive at an assessment. The subject's visual acuity is then measured when the subject's head is moving and a display object is fixed to arrive at a first dynamic measurement. The subject's visual acuity is also measured when the subject's head is fixed and the display object is moving to arrive at a second dynamic measurement. The assessment and the first and second dynamic measurements are then used to determine an impairment of the subject's gaze stabilization system.
