Sudden changes in your vision are signs of a potentially serious eye problem, one that could lead to vision loss. Dr. Jeevan Mathura and Dr. Lindsay Smithen at Retina & Macular Disease Specialists have extensive experience determining the cause of sudden blurry vision and initiating the treatment you need. If you have any questions or concerns about your vision, call their office in Arlington, Virginia, or schedule an eye exam online.
Suddenly developing blurry vision can be normal. It may occur when you quickly move between far and close objects, causing sudden blurriness as your eyes accommodate to the new depth.
You may experience sudden blurriness if you have extra tears in your eyes. A minor viral or allergic conjunctivitis could even be the culprit.
In many cases, however, a sudden change in vision, including blurry vision, is a red flag indicating a potentially dangerous problem. Even if it’s nothing to worry about, it’s always better to protect your sight and consult your doctor at Retina & Macular Disease Specialists as soon as possible.
Multiple eye conditions can lead to sudden blurry vision.
Your retina can break away from its underlying tissues, causing symptoms such as the sudden appearance of floaters, flashes of light, and sudden blurry vision. If you have these symptoms, get an eye exam as soon as possible. Without quick treatment, retinal detachment causes blindness.
Retinal vein occlusion
When small blood vessels that serve the retina become damaged or blocked, you’ll experience sudden vision changes. Blurriness is one possible symptom, but if the occlusion is severe, you could have vision loss.
Acute anterior and intermediate uveitis
Uveitis is an inflammatory disease that occurs in different parts of your eye. An acute case of anterior uveitis and intermediate uveitis causes sudden blurred vision, as well as floaters, eye pain, and sensitivity to light.
The vitreous is a clear gel-like liquid found inside your eye. When blood vessels that supply the retina leak or rupture, blood can flow into the vitreous, causing sudden blurry vision. Diabetic retinopathy may cause vitreous hemorrhage.
A small break in the macula results in sudden blurry vision.
Your eye can become infected with the herpes simplex virus, which quickly develops into an acute infection that causes sudden eye pain and blurriness.
Health problems that occur outside your eyes can cause your vision to become blurry suddenly. Blurred vision and double vision are symptoms of a stroke, or they can also be early signs of multiple sclerosis.
Abnormal pressure in your head can cause blurry vision. That could develop from bleeding, a brain mass, or possibly severely high blood pressure. Other causes of sudden blurriness include migraine headaches and head injuries.
