Epiretinal membrane and pinpoint blue flashes

Discussion in 'Optometry Archives' started by Harrison Rigby, Jan 14, 2005.

  1. Dear fellow eyeball fans:

    I'm a 54 y/o male in South Carolina. I'm quite myopic, as in -8. Last
    April I had a posterior vitreous detachment in the left eye that resulted
    in 2 retinal holes at the 10 o'clock and 1 o'clock positions
    (non-inverted, physical locations from the perspective of looking out).
    The holes were at the sites of lattice generation and were sealed with
    cryopexy.

    In September I had a retinal detachment at the 7 o'clock position
    (non-inverted, looking out) that was treated with cryopexy and a scleral
    buckle. Soon after the scleral buckle procedure I began noticing visual
    distortions (the famous wavy lines) and returned to the surgeon for a
    followup examination. He did an OCT exam and told me that I did have some
    scar tissue growing across the macula but that the macula looked healthy
    overall. He also pronounced me in good condition and gave me a new
    prescription for my glasses.

    In the last few weeks I have begun seeing brilliant pinpoint flashes of
    blue light around the macula. They are usually scattered around the macula
    but occasionally occur right at the center of the macula, and when they do
    they are very intense and appear as a small circle of blue with a round
    central region that is black. These flashes occur regularly during the
    day, as in several per minute, and seem to be more frequent when I am
    active, as in the moments after climbing the stairs at work.

    There's another thing that I'm curious about. In the mornings, immediately
    after awakening, I see something in the left that must be the result of
    the detached vitreous contacting the retina. I see an opaque region of
    bright red, to the immediate right of the macula, that is generally
    circular in shape but has an irregular edge. This area grows in size from
    a small spot to a large region and then diminishes to a spot again before
    disappearing. This happens in a period of about one minute. Around the
    edge of this region of opaque red there is a thin band of brilliant
    yellow. My naieve assumption is that while sleeping some portion of the
    vitreous is shifting and pressing against the retina. When I get up the
    vitreous reverses its direction - the bright yellow ring is the region
    where the vitreous is pushing against and then peeling away from the
    retina - the area of greatest mechanical stimulation.

    I wonder if any of you have experienced these things or can suggest what
    they might be?

    Thanks,

    Harrison

    Hello, Mr. Tyner,
    it seems you doctors have not great succes in curing eye problems.

    Do you think your branch of medicine and medical business has the same
    rate of success of other branches?

    What is your opinion about your own practice?

    Are you satisfied with your clients?


    Now take this poor patient.

    He had been distressed by long years of wearing great -8 comensative
    glasses, which have produced, if logic is logic, such great damages in
    the retina, that the poor man now feels worried by these sparks, and
    you suspect migraine...

    Please, if you were in his own shoes, what would you have done?
    Thank you for your always kind replies.

    Harrison,
    I'm a fellow scleral buckle wearer and have no experience with the
    strange color effects you describe. I hope they go away and that
    someone can offer a useful explanation of them.
    My retinal detachment follow up exam also revealed scar tissue across
    the macula. Probably you are already well-informed on this, but do
    watch carefully the "wavy line" effects and overall vision quality for
    any further changes (murkiness, fuzziness) and vision loss. My
    post-surgery macular scarring was severe enough to cause "retinal
    pucker" and significant vision loss. It required more surgery: a
    retinal peel with vitrectomy. More details with a great explanation of
    some retinal physiology by MR in a previous thread here (Jan. 7 I
    think), titled "Retinal Surgeries."

    I would seem to me that these events could be caused by vitreous
    traction on the macula, and may be early signs of an impending macular
    hole. I think you should discuss this with your retinal specialist on
    Monday. Most patient I have seen with epiretinal or pre-retinal
    membranes do not have photopsia.
