of an Eye Stroke
An eye stroke can be very dangerous for your vision. This condition is
also frequently known as stroke of the optic nerve or ischemic optic
neuropathy. The condition is sudden like a brain stroke.
Strokes normally happen when the blood supply to a specific organ is
reduced or cut completely. In this case the blood supply is unable to
reach the optic nerve. This happens as the artery responsible to
deliver the blood to your eye is blocked or damaged. The problem is
without blood to deliver oxygen and nutrients to your eyes, the optical
nerve and its surrounding tissue will get adversely affected.
The eye stroke can be caused by a wide variety of factors.
conditions that might trigger a stroke of the optic nerve are:
- diabetes, heart disease
- high levels of cholesterol
atherosclerosis of small blood vessels
- an unusually high intra ocular
pressure can also be a cause of the problem
The systemic arterial disease can cause a severe inflammation of the
arteries which can lead to an arteritic stroke. The narrowing of the
arteries that result from this disease can interrupt the blood flow so
drastically that an infarction can occur. The optic nerve can be
susceptible to this type of inflammation. This type of eye stroke is
especially dangerous as the damage caused is often irreversible.
There are a couple of symptoms associated to this condition some of
them are: light sensitivity, vision loss, problems with depth
perception and problems with the peripheral vision.
The sensitivity to light is the inability of the eye to handle regular
glare. Any brightness is likely to bother the eye. Losing vision is
another symptom. The amount of vision lost is directly proportional to
the damage suffered by the optic nerve.
If the damage is too much even
the ability to perceive light can be lost. This can also be
progressive, as time passes the vision loss can increase.
Your depth perception can also be affected partially or totally by the
condition. The ability to distinguish three dimensional objects can be
severely impaired by problems in the optic nerve.
What is considered normal eye pressure
The visual field can decrease as a result of a stroke in the eye as
well. A person can end up with tunnel vision if the stroke is severe
enough. The treatment for this type of condition will usually require
some medication to relieve the pressure on the optic nerve. This can
decrease the damage suffered and will prevent a further decrease of the
vision. As soon as you perceive any kind of symptom that could resemble
this condition go to your doctor immediately.
