Obscured vision due to papilledema may last only seconds, while a severely atherosclerotic carotid artery may be associated with a duration of one to ten minutes. [6] Certainly, additional symptoms may be present with the amaurosis fugax, and those findings will depend on the cause of the transient monocular vision loss. [citation needed]
Treatment is dependent on the underlying aetiology. Organic causes may include systemic or ocular medications, brain stem injury, or active ocular inflammation such as uveitis. Functional pseudomyopia is managed though modification of working conditions, an updated refraction, typically involving a reduction of a myopic prescription to some ...

[29] This is due to a decrease in preventable or avoidable causes of blindness with the improvement and focus on maternal and neonatal healthcare worldwide.

A greyout is a transient loss of vision characterized by a perceived dimming of light and color, sometimes accompanied by a loss of peripheral vision. [1] It is a precursor to fainting or a blackout and is caused by hypoxia (low brain oxygen level), often due to a loss of blood pressure. Greyouts have a variety of possible causes:

Childhood blindness is an important contribution to the national prevalence of the disability of blindness. [3] Blindness in children can be defined as a visual acuity of <3/60 in the eye with better vision of a child under 16 years of age. [4]
