Amaurosis

Amaurosis is defined as temporary loss of vision of one eye due to the absence of blood circulation in the retina.

Amaurosis, also known as temporary monocular blindness, is not considered a disease but a symptom of some disorders such as optic neuritis, brain tumors o multiple sclerosis

Any sudden loss of vision, no matter how transient, should be treated immediately by an ophthalmologist to treat it as soon as possible.

What is amaurosis?

The definition of amaurosis or temporary monocular blindness is described as the sudden loss of vision in one of the two eyes due to the absence of blood circulation in the retina.

Under our experience, patients with amaurosis ensure that in the campor visual a gray spot appears o black which is going down the eye until the whole vision is compromised for a few seconds or minutes.

Determining the cause of this condition is important to treat it in time and avoid further complications associated with this symptom, such as diseases of the immune system and brain conditions. 

Types of amaurosis

Amaurosis can be bilateral or unilateral, although in most cases it occurs in only one eye.

Bilateral

Sudden and transient loss of vision in both eyes. 

Unilateral

Sudden and transient loss of vision in one eye.

When can we talk about fleeting amaurosis?

Most medical specialists refer to a fugax, or fleeting, amaurosis as a sudden and transient blindness associated with a vascular problem.

Said vascular problem is the cause of there is no blood circulation in the retina, the light-sensitive tissue where images are projected. 

Causes that cause it

Our most frequent causes that can cause a fleeting amaurosis and facilitate its diagnosis are: 

  • La presence of a clot produced because a plaque, from a longer artery, such as the carotid in the neck or one from the heart, travels to an artery in the eye and blocks the blood circulation to the retina.
  • La inflammation of the optic nerve, better known as optic neuritis.
  • Blood vessel disease called polyarteritis nodosa, and that causes inflammation of the medium and small arteries.
  • La autoimmune disease "systemic lupus erythematosus” or simply lupus, which is characterized by the cells of the body's immune system attacking healthy tissue.
  • La multiple sclerosis, disease that causes attacks on the nervous system due to a failure of the immune system.
  • Tumors brain
  • Head injuries.

Symptoms of Leber's congenital amaurosis

Leber's congenital amaurosis is a condition that originates from birth and affects people with severe visual impairment.

Those born with congenital Leber amaurosis usually have the following symptoms: 

  • Visual loss or blindness It affects from birth due to the absence of photoreceptor cells known as cones and rods. Vision loss can also occur during the first months or years of life and, in most cases, is permanent. 
  • Alteration in the cornea curve or keratoconus It may be caused because the person rubs his eyes repeatedly. 
  • Hollow eyes, better known as enophthalmos.
  • Squint.
  • Irregular eye movements.
  • Sensitivity to light.
  • Weak pupillary response
  • Opacity of the lens

Transmission

The fleeting amaurosis is a symptom of various disorders, for this reason the treatment for this type of blindness Depends solely on its cause..

When temporary monocular blindness is caused by vascular problems you can opt for the stent placement by surgery to prevent the collapse of one of the coronary arteries. 

If amaurosis is associated with a glaucoma, it is important to thoroughly review the fundus and evaluate the option to change or adjust glaucoma treatment.

Can it be prevented?

The fleeting amaurosis is caused, in most cases, by a plaque that clogs an artery and compromises the blood flow of the retina.

Plaque is a substance formed by the accumulation of cholesterol and lipids in the blood, a scenario that can be avoided or reversed if adopted healthier eating habits

Avoid fat intake and choosing a balanced diet rich in fruits, proteins and vegetables is an excellent way to control blood cholesterol levels y prevent diseases associated with amaurosis such as diabetes and hypertension

Also, it is important to identify if there are family background of transient blindness to speak with the attending physician and take actions that help prevent the causes of this problem.
