Loss of vision is considered sudden when it develops in a few minutes to a few days. Sudden loss of vision may occur in one or both eyes. It also doesn’t have to mean total blindness. Sudden loss of vision can be partial, total, or seem more like blurry vision. It could last for a few minutes, hours, or become permanent.
Three of the primary causes of sudden loss of vision are:
Clouding of normally transparent eye structures
When light passes through your eye, it travels through the cornea, the lens, and the vitreous, which is the gel-like fluid that fills the center of your eye. All three areas must be transparent or light will be blocked and you’ll lose vision.
The retina is the delicate layer of tissue at the back of your eye that contains millions of photoreceptor cells essential for vision. The cells collect light that enters the eye, convert the image into nerve impulses, then send the message to the brain so that you can see the image.
Damage to any of the nerves in your eye can affect vision, but the optic nerve is especially vital because it connects the retina to the brain.

Your doctor at Retina & Macular Disease Specialists performs a comprehensive eye exam that includes standard tests and a dilated exam to get a close look at your retina and other internal structures. After the underlying cause of your vision loss is determined, your doctor develops a treatment plan that addresses your health needs.
