    Subject: Follow-up on Stress and Visual Dysfunction

    When I was the neurosensory diagnostician in the Department of
    Ophthalmology at Sinai Hospital in Detroit, I was referred a patient, a
    15 year-old girl who was a straight "A" student and captain of her high
    school archery team in urban Detroit. Two adverse incidents occurred to
    her within a week: she was assaulted at knifepoint and a few days later
    witnessed her best friend gunned down in a drive-by gang shooting.

    Her psychic traumas resulted in psychiatric hospitalization. She
    concurrently had a profound loss of vision, reduced to finger counting,
    with overall depression of the visual fields and more significant
    altitudinal losses similar to those seen in non-arteritic ischemic
    neuropathy. Over the period of months her vision had degraded to hand
    motion.

    With all other ophthalmnic disease ruled out, her doctors felt strongly
    that her visual losses were hysterical in nature due to her trauma. She
    was referred to me to rule out hysteria or malingering.

    Her (very closely observed) neurosensory workup showed severely
    depressed and slightly delayed flash VEPs, nearly extinguished pattern
    VEPs and reduced flash ERGs. All attempts to detect malingering were
    negative, including a lack of tubular or spiral fields. Follow-up
    testing a few months later yielded identical results.

    After about a year she was declared legally blind and is receiving
    services from the Michigan Commission for the Blind.

    Our best guess was that this sudden, physiological loss of vision
    coincident with her profound psychological trauma may have been caused
    by stress-induced vascular spasm and ischemia.
