    Effect of ethnic diversity on the saccadic reaction time among healthy Indian and Dutch adults

    Eye movement perimetry (EMP) expresses the decline in visual field (VF) responsiveness based on the deviation in saccadic reaction times (SRTs) from their expected age-similar responses (normative database). S...

    Saccadic reaction time in mirror image sectors across horizontal meridian in eye movement perimetry

    In eye movement perimetry (EMP), the saccadic reaction time (SRT) to ‘seen’ visual stimuli are delayed in glaucoma. Evaluating SRT behaviour in hemi-field sectors could refine its clinical implication. The dev...
