    SDN Members don't see this ad. (About Ads)
    I'm thinking it means a drop in both eyes. bid I can't figure out. How about tid/qid?

    I'm sorry, it's probably a stupid question but if someone tells me I'll never ask again.

    Thanks.

    Thanks a lot.

    I thought it had to be something like that. I know guttatum is latin for drop so gtt=drop makes sense.

    How's OU both eyes? Oculi Universalis or something?

    BID/TID/QID I won't even think about. At least I know.

    Thanks again.

    o.d. -- oculus dexter, right eye
    o.s. -- oculus sinister, left eye
    o.u. -- oculus uterque, each eye

    My orgo professor said that anyone who is left-handed must be sinister, and since then I've never had a problem remembering o.d./o.s. ;)

    b.i.d. = bis in die (Latin meaning twice a day)
    t.i.d. = ter in die (latin for 3 times a day)
    q.i.d. = quater in die (latin for 4 times a day)
    q.d. = quaque die latin meaning every day
    hope this helps!
