Central retinal artery occlusion, or CRAO, is a condition that occurs when blood traveling through the central retinal artery becomes blocked. The condition was first described in the mid-1800s. Today, we have a better understanding of what it is and how to treat it.

Central Retinal Artery Occlusion Symptoms

Patients will experience a sudden loss of vision in one eye. There is no pain, but a funduscopy can reveal the appearance of a red lesion, often referred to as a cherry red spot. The red area is surrounded by pale retina which is caused by restricted blood flow. Anyone who experiences sudden vision loss should seek medical assistance immediately to determine if central retinal artery occlusion or another eye condition is the cause.

Central Retinal Artery Occlusion Treatment

There are multiple treatment options available to patients suffering from central retinal artery occlusion, including:

• Ocular massage
• Inhalation therapy
• Anterior chamber paracentesis

Patients in North America may opt for Hyperbaric Oxygen Therapy which is only available through the Undersea and Hyperbaric Medical Society. This treatment may be covered by vision insurance, so contact your insurance provider to learn more about available benefits and costs.
