Sudden Vision Loss

• Loss of vision can occur suddenly or develop
  gradually over time. Vision loss may be complete
  or partial, involving only one eye or even
  certain parts of the visual field. Vision loss
  can also be considered as loss of sight that
  cannot be corrected to a normal level
  with spectacles. Sudden visual loss is a common
  problem with different presentations among
  patients of different ages. Variation in
  frequency ranges from a single episode to many
  episodes per day recurrences may continue for
  years but more frequently occur over seconds to
  hours.

What are the causes of sudden vision loss?

• Sudden vision loss is usually attributed to a
  reduction of the amount of oxygen and nutrients
  to the tissues of the eyes, resulting in
  temporary or permanent damage to the retina
  (ischemia). Ischemia has various causes and can
  appear in different forms. It may indicate high
  blood pressure.
• Fleeting Blindness lasts from a few moments to
  several minutes, and disrupts the vision before
  continuing inwards. Along with this condition,
  other symptoms include temporary loss of feeling
  on one side of the body and impaired speech. This
  form of vision loss is most common in adults 50
  years of age and older.
• An ocular migraine may cause transient wavy
  vision or a blind spot in one or both eyes. The
  visual aura may be accompanied by a headache.
  This sudden loss of vision can be quite
  disturbing.

What are the causes of sudden vision loss?

• Another cause of sudden vision loss in older
  individuals is giant cell arteritis. This is
  an autoimmune disorder in which the blood
  vessels, especially those around the eyes, become
  inflamed and swollen reducing blood flow. The
  symptoms are similar to but in some cases not as
  abrupt as those of fleeting blindness. Vision
  loss due to giant cell arteritis may be
  permanent.
• Vision loss can also occur as a result of
  increased intracranial pressure. Hypertension can
  cause decreased circulation resulting in a stroke
  in the eye. Vision loss can also be the result of
  a tumour, although generally the start of the
  vision changes is less abrupt.

Symptoms

• Sudden vision loss not necessarily has to be
  complete loss of vision. In some cases the
  affected area might just be the periphery, and
  often the vision loss only affects one eye. In
  other cases, the vision loss may appear as a gray
  splotch that blocks sight. Sometimes the loss of
  vision might only last a few moments. In other
  cases, the impairment can last minutes or even
  hours, or the rest of your life.

Treatments

• If you have experienced sudden loss of some or
  all vision in one or both eyes call an eye doctor
  immediately. Book an appointment with
  an ophthalmologist quickly. If it is not possible
  to find an ophthalmologist nearby, you can always
  go online. Remember, sudden vision loss can be an
  indicator of much more serious issues that it is
  vitally important to diagnose quickly and treat.
