The eye is supplied with blood and nutrients through arteries and veins in the eye. When blockages of these blood vessels occur, it is called an occlusion.

If the oxygen-carrying blood brought to your retina, by means of the artery, is occluded your retina cannot receive the much-needed supply to your cells in your retina. This process is painless, but you will experience a loss of vision.

Retinal Artery / Retinal Vein Occlusion

If the retinal vein taking blood away is occluded, your veins will leak or hemorrhage. This process is also painless and you may experience loss of vision.

As with any sudden change in your vision, you must contact your Middlesex Eye Physicians ophthalmologist for evaluation.
