Photopsia
  • Photopsia is the term that is used for the
    condition when people appear to see flashes of
    light. Frequently, these flashes appear alongside
    a migraine, and in fact, migraine sufferers use
    the flashes as a signal of an upcoming
    migraine.Those people over the age of 65 are
    the most likely to be affected, and the most
    common cause of these eye flashes is the
    shrinkage of the vitreous humor within the
    eye. The vitreous humor is the transparent
    substance in the centre of the eyes, mostly made
    up of water, and is responsible for the shape and
    form of the eye.

  • Usually, photopsia is caused by the shrinking of
    the vitreous humor, which applies tension to the
    attachment points, which agitates the retina
    causing the emission of electrical impulses that
    are interpreted as flashes of light by the
    brain.  Vitreous humor shrinkage is not the
    only cause of photopsia. For example, severe
    impact to the head can easily cause the retina to
    pull away from the eyeball, and when this happens
    momentary flashes of light may be seen.As
    mentioned, photopsia can be the signal for the
    onset of a migraine. Migraines may be caused when
    the blood vessels in the brain quiver, or if the
    retina becomes detached from connecting nerves.

  • The flashing lights, which may look like sparks,
    zig zags or lines of light, may last for a brief
    period or be longer lasting throughout the course
    of the migraine.This perception of flashes of
    light should be treated seriously, and prompt
    investigation by a medical professional is
    advisable.Generally speaking, the experience of
    eye flashes is no reason for concern, but in very
    rare instances, photopsia can lead to certain
    levels of loss of vision.During the normal
    ageing process, the vitreous humor will shrink,
    becomes thinner, and will begin to pull away from
    the retina.

  • In fact, approximately two thirds of the over
    65s will be affected by some degree of vitreous
    humor shrinkage, leading to many experiencing
    flashing lights.It should be kept in mind that
    a major increase in the number of photopsia
    occurrences can possibly indicate a torn
    retina.Clearly, it is essential to recognize
    and understand photopsia signs.
