    Using a digital pupilometer

    What is the correct way to use a handheld digital pupilometer to take a pt's PD? I've been told a few different ways in my time, so I just thought I'd throw it out here. Do you set it to infinity and view both eyes? or one eye at a time? Set it to 40cm or 30? to get a near PD or just subtract 1.5mm from the distance PD? We don't have a user manual where I work now and some opticians are using it differently. Thanks

    I've always used it set to infinity and with both eyes. Then, I check using setting for each individual eye.

    set to infinity and measure binucularly. unless special case such as alternating phoria may need to do it monocularly.

    Grateful to be what I am, and not pretending to be someone I am not!

    Set it for what you are fitting for.
    PAL: Monocular at ∞
    S.V. (anything): Monocular at relative Rx dictated distance.
    FT or TRI: Binocular (unless the monocular difference exceeds visual/comfort performance - be sure to explain cosmetic outcome)
    Balance: Monocular (at relative Rx dictated distance) 'skewed' to working eye.
