Central retinal artery occlusion

Frequency and characteristics of central retinal artery occlusion

The occlusion of the central retinal artery is estimated at 2.2 per 100,000 inhabitants.
Patients diagnosed with CRAO have a life expectancy of 5.5 years compared to 15.4 years for age-matched non-CRAO patients.
Patients with CRAO often present with a unilateral loss of light perception. However, visual acuity can vary from loss of light perception to counting fingers. An immediate examination by an ophthalmologist must be carried out. At the fundus, the retina appears diffusely pale with a cherry-red central spot.


The goal of treatment is to immediately restore retinal circulation.

Most of the time it is treated intensively, 2-3 times per day; more recent studies treat it until the new vessels have formed in the retina.
