The patient with central retinal artery occlusion will present with sudden acute, painless loss of vision in one eye.

A carbogen mixture of 95% oxygen and 5% carbon dioxide can be used as part of the early treatment of central retinal artery occlusion.

Avoid epinephrine, commonly mixed in with local anesthetics for vasconstriction, in seeing eyes as this can cause a central retinal artery occlusion.

The cherry red spot is seen in central retinal artery occlusion, appearing several hours after the blockage of the retinal artery occurs.

A cherry-red spot is a finding in the macula of the eye in a variety of lipid storage disorders and in central retinal artery occlusion.

This is the basis of the famous "Cherry red spot" seen on examination of the retina on funduscopy of a central retinal artery occlusion (CRAO).

Central retinal artery occlusion (CRAO) is a disease of the eye where the flow of blood through the central retinal artery is blocked (occluded).

In 2009, the Undersea and Hyperbaric Medical Society added "central retinal artery occlusion" to their list of approved indications for hyperbaric oxygen (HBO).

As with central retinal artery occlusions, ophthalmic artery occlusions may result from systemic cardiovascular diseases; however, a cherry-red spot is typically absent and the vision is usually worse.

Catheter guided thrombolysis can be used to treat sudden blindness secondary to blocks in the central retinal artery (central retinal artery occlusion)when used within 6 hours of the onset of symptoms.

Conditions that affect or destroy the retina include retinal detachment; macular disease (e.g., macular degeneration); and retinal vascular occlusions, the most important of which is central retinal artery occlusion.
