Overview

Acute zonal occult outer retinopathy is a rare condition that affects the eyes. People with this condition may experience a sudden onset of photopsia (the presence of perceived flashes of light) and an area of partial vision loss (a blindspot). Other symptoms may include "whitening of vision" or blurred vision. Although anyone can be affected, the condition is most commonly diagnosed in young women (average age 36.7 years). 

Symptoms

• Sudden vision impairment
• Flashing lights
• Enlarged blind spot
• Inflamed retina
• Eye pain

Causes

The underlying cause of AZOOR is currently unknown; however, some researchers have proposed that infectious agents (such as viruses) or autoimmunity may play a role in the development of the condition. 

Treatment

No treatment has been proven to improve the visual outcome of AZOOR; however, systemic corticosteroids are the most commonly used therapy.
