Treatment:

Treatment depends on the results of the evaluation. If there is evidence of blockage of more than 70% of the carotid artery, the patient may be considered for surgery to remove the blockage.

The decision to do surgery will also be based on the presence and severity of other medical problems and the general health of the patient. If the patient is not a surgical candidate, treatment with aspirin or another blood thinning agent may be warranted.

Lowering cholesterol, reducing high blood pressure and cessation of smoking can help decrease the risk of atherosclerosis.

New techniques include stenting of the carotid artery and balloon angioplasty of the stenosis (blockage) in the carotid artery. Both techniques aim to open up the region of the carotid artery that is being blocked by plaque. These techniques are promising, especially for patients who are not well enough to undergo major surgery.

Expectations (prognosis):

Amaurosis fugax may be a sign of impending stroke. The attack itself does not result in any permanent disability.

Complications:

Though this condition does not result in any permanent damage, it is a sign of atherosclerotic disease and therefore implies a serious risk for stroke.

Calling your health care provider:

Call your health care provider if any loss of vision occurs. If symptoms last for longer than a few minutes, or if there are any other symptoms accompanying the visual loss, it is important to seek immediate medical attention.
