Have you ever suddenly lost sight or experienced blindness even if only for a moment? Even though it's only temporary and your vision returns in a few moments, of course this incident can make you panic. In this discussion, we will explain the four most common reasons why you can suddenly lose your vision. Listen carefully, yes.
Causes of sudden vision loss
1. Papilledema
Papilledema is a condition of swelling in the nerve area of the eye. Papiledema can result from increased pressure on the head.
Vision loss or blindness will occur in both eyes at the same time. Often this momentary loss of vision is accompanied by headaches. Fortunately, this usually only happens within seconds. After that your eyesight will return.
An MRI scan is one of the supporting examinations that will be carried out to help determine the cause of the increased pressure in the head.
2. Amaurosis fugax
Loss of vision in one eye without pain that occurs within seconds to minutes is a hallmark of this condition. Amaurosis fugax is more common in those of you aged over 50 years with a history of diseases such as diabetes, high blood pressure (hypertension), and cholesterol profile disorders (hyperlipidemia).
The most common cause of this condition is blockage of the blood vessels in the retina area. In some cases, especially those of you who experience vision loss for more than 90 minutes, the blockage can persist and vision loss can occur permanently. Investigations using a CT scan can be done to assess the condition of other brain blood vessels.
3.A artery insufficiency in the brain (vertebrobasiler insufficiency)
A sudden decrease in vision in both eyes that occurs repeatedly without pain is the hallmark of this condition. Not much different from amarousis fugax, this condition is also more common in those of you who have certain diseases.
MRA supporting examination (magnetic resonance angiography) may need to be done in addition to a CT scan. This examination is useful for seeing the blood supply to the area behind the brain (occipital), brainstem, and cerebellum. Impaired blood flow that occurs in these areas may cause sudden loss of vision in both eyes.
4. Migraine
Temporary loss of vision (between 10-60 minutes) may soon be followed by a severe headache on one side (migraine). This incident will repeat every time a migraine attack comes. Migraines like this are commonly known as migraines with aura.
Loss of vision in this state of affairs is not very worrisome. The reason is, vision will return to perfect after a migraine attack can be overcome.
However, never underestimate the loss of your vision even if it is temporary. Immediately consult yourself to the nearest ophthalmologist to make sure there are no significant problems with your eyes or blood vessels as a whole.
