Glaucoma, Refraction Errors and Heavy Computer Usage Correlated

Discussion in 'Optometry Archives' started by camus' justice, Nov 16, 2004.

  1. There is a highly statistical relationship between heavy computer use and
    glaucoma in people with refraction at either end of the scale.

    Heavy Computer Use and Development of Glaucoma in Short-Sighted People

    The actual journal article is at:

    The study was done in Japan (where there is a very high incidence of angle
    closure and open angle NTG glaucoma). Further work obviously needs to be
    done to determine if this conclusion can be generalized to groups of other
    racial/genetic origins. This was a prelim study and leaves many questions
    (particularly the proposed mechanism) unanswered.

  2. We should wait for confirming studies before deciding that computer users
    It is evident that you will never be able to state anything
    definitely, either in one sense or the other, since the variables at
    stake are too many, and the most important thing of all, the way the
    eyes are used by the mind, is not even conceived in the minds of the

    Dear Rishi,

    According to MT, we should wait till hell freezes over
    before we do anything at all.

    Hell with the screening - I'm going to start smoking and eating doughnuts.
    The fat guys who smoked had the least glaucoma in the study.

    Makes ya' just love uncontrolled cross sectional statistical studies...

    This perfectly illustrates your head-in-the-sand approach. In the 1970's,
    there was still a group of optometrists who believed in using bifocals and
    reading glasses to prevent myopia. This approach was taught in every
    optometry school, not as gospel, but as an approach to consider. Since
    then, numerous studies have confirmed the clinical experiences of most of
    us, which is that the accommodative approach to myopia prevention simply
    doesn't work, or has such a small effect, or works on such a minority of
    patients, that the use of such techniques has been virtually abandoned.

    Of course, the research into prevention did not stop in the 1970's. The
    search for a physiologic mechanism has led scientists to discover the
    existence of receptors within the eye at the level of the retina that
    respond to a blurred image. This process is independent of accommodation.
    This research has led to the identification of pharmaceutical agents that
    can block these receptors such that myopia can be either prevented or
    slowed by half.

    The cause(s) and source(s) of the blur in the image are still under
    investigation, with some researchers suggesting that the quality of the
    peripheral image secondary to the oblate shape of the myopic eye is a key

    Contrary to what Otis and his friends suggest, there is much ongoing
    activity in the study and prevention of myopia, but in a completely
    different direction. Otis is stuck in an idealogical "time warp" from
    which the rest of us have moved on.

    Dear Otis,
    No, according to MT, one should take studies like this with a
    grain of salt. Why don't you get a life.
