What’s Behind Sudden Blurred Vision?

Blurry vision is not an uncommon occurrence. It can either be slow and progressive or quick and sudden. The former is caused by long-term medical conditions, while the latter typically stems from a single event. Not all instances of sudden blurred vision are a cause for concern, but some may require immediate attention from an experienced eye doctor. Read on as we discuss the possible causes of this symptom.

Concussion

A concussion is a head injury that temporarily affects brain function. Apart from visual changes, symptoms may include confusion, headache, dizziness and mood change. A quick visit to a doctor should determine the extent of the injury. If it is not severe, treatment is mainly focused on reducing symptoms. For instance, the patient may be required to rest for at least a day or two.

Retinal Detachment

This condition occurs when the retina, which is the thin layer of tissue on the back of the eye, pulls away from its normal positioning, restricting blood supply. Symptoms can include diminished peripheral vision, the appearance of “floaters” and flashing lights. It is considered a medical emergency and must be treated right away. An optometrist may recommend either freeze treatment or surgery.

Optic Neuritis

This condition refers to the inflammation of the optic nerves that connect the eyes and the brain. In addition to blurred vision, symptoms may include loss of color vision, flashing lights and discomfort around the eyes. A visit to an eye care provider can help determine the extent of this condition. While it usually improves on its own, a steroid prescription may be required to expedite recovery.

Eye Infections

Blurred vision is a common symptom in various types of eye infections such as keratitis (corneal inflammation), uveitis (inflammation of the middle part of the eye), and conjunctivitis (inflammation of the blood vessels in the membrane around the eyeball. These require swift medical treatment depending on the severity of the other symptoms like redness, excessive tearing and discharge.
