Amaurosis fugax (derived from the Greek “amaurosis,” which means dark, and the Latin “fugax,” which means fleeting) basically means a temporary loss of vision in either one or both of the eyes.The term ‘Amaurosis Fugax’ is used when visual loss is noted involving one or both eyes and can be attributable to any origin.
What are the other names for amaurosis fugax ?
The term “transient monocular blindness” is also frequently used but is not considered ideal, as most patients don’t experience total loss of vision with the episodes. However, “Transient monocular visual loss” (TMVL) or “transient binocular visual loss” (TBVL) are both preferred to explain abrupt and passing loss of vision in one or both eyes, since they bear no connotation concerning etiology.
What is the pathology behind amaurosis fugax ?
There is a transient visual loss in this condition. This includes both monocular or binocular loss of vision and basically encloses a diverse group of disorders, some moderately benign and others with grave neurologic or ophthalmologic consequences. These include stroke, ocular disease, transient monocular blindness as well as migraine.
What are the symptoms of amaurosis fugax ?
- Vision loss can be unilateral or bilateral. Transient visual loss (TVL) from any cause can be described as mild blurring or fogging to complete blackness, and may involve a part of or all of the visual field.
- It is fleeting/ temporary. Transient visual obscurations typically last seconds. Thromboembolic events from cardiac disease usually last 1 to 15 minutes and only rarely an hour or more. Migraine aura characteristically lasts 10 to 30 minutes
- A bright visual aura can be felt sometimes, but not as obvious as dimmed sight or vision that appears either blacked out or gray.
How do you diagnose amaurosis fugax ?
Pertinent medical and family history may guide the underlying diagnosis. The examining clinician utilizes the clinical history and assessment to confine the problem to specific areas of visual pathways, recognize potential etiologies, and, when needed, do laboratory tests to confirm or eliminate certain causes.
- A thorough evaluation of the fundus is an important part of the assessment of patients with transient visual loss. Ophthalmology referral is required for all patients.
- Carotid Artery Evaluation also has to be done.
