Retinal Artery Occlusion

A retinal artery occlusion occurs when the central retinal artery or one of the arteries that branch off of it becomes blocked. This blockage is typically caused by a tiny embolus (clot) in the blood stream. The occlusion decreases the oxygen supply to the area of the retina nourished by the affected artery, causing permanent vision loss.

Signs and symptoms of Retinal Artery Occlusion

  • Transient loss of vision prior to the artery occlusion (in some cases)
  • Sudden, painless and complete loss of vision in one eye (in central artery occlusion)
  • Sudden, painless, partial loss of vision in one eye (in branch artery occlusion)

Detection and diagnosis of Retinal Artery Occlusion

Artery occlusion is diagnosed by examining the retina with an ophthalmoscope.

Treatment of Retinal Artery Occlusion

Unfortunately , there is no treatment that can consistently restore vision loss from an artery occlusion. However, if it is caught within the first hour and treatment is initiated immediately, recovery is possible in rare cases.

The following conditions increase the risk of problems that may affect the vessels of the eye:

  • High cholesterol
  • Heart disease
  • Arteriosclerosis
  • Hypertension
  • Diabetes
  • Glaucoma

Εylea (aflibercept) intravitreal injections treatment

Aflibercept is a pharmaceutical substance of the drug Eylea. This substance inhibits the activity of a group of factors, known as vascular endothelial growth factors (VEGF) . In patients with central retinal artery occlusion, the central retinal artery or a branch of it is blocked.This results in increase levels of vascular agents (VEGF factors), causing increased macular edema, which because of the fluid collection causes opacities on our vision.

How Eylea is administered?

In the case of secondary macular edema from central retinal vein or artery occlusion personalized treatment is applied, which is determined by your doctor. The frequency of injections which is indicated is one (1) per month. In any case, your doctor will decide whether a patient should continue or discontinue therapy with intravitreal injections. The determinant factor is the improvement of the condition or not, which is judged by measurements of both visual acuity, but mainly by optical coherence tomography (OCT).
