What is TMB syndrome?
Abstract. Transient monocular blindness (TMB) or amaurosis fugax is diagnosed when visual disturbance or loss (blindness, dimming, fogging, blurring) affects one eye for seconds or minutes. TMB may occur alone or in combination with transient hemispheric ischaemia (TIA).
How is amaurosis fugax diagnosed?
Tests that may be done include: Ultrasound or magnetic resonance angiography scan of the carotid artery to check for blood clots or plaque. Blood tests to check cholesterol and blood sugar levels. Tests of the heart, such as an ECG to check its electrical activity.
What is monocular visual loss?
In general, monocular vision loss indicates an ocular problem or a problem anterior to the optic chiasm, and the vision loss may respect the horizontal midline. Binocular vision loss is usually cerebral in origin and often respects the vertical midline.
How do you fix monocular vision?

What are the most common treatments for monocular diplopia?
Treatment for monocular diplopia is often related to fixing a refractive error like astigmatism. This may be done through specialized corrective prescription eyewear or corrective refractive error surgery like LASIK or cataract surgery. Dry eyes can be helped through eye drops.
What causes central vision loss?
