In this photograph, the affected area of the retina is the pale, whitish-yellow region (blue arrow) that is normally supplied by the blocked artery. The surrounding reddish-orange area is healthy retina tissue.
• Transient loss of vision prior to the artery occlusion (in some cases).
Central artery occlusion
• Sudden, painless and complete loss of vision in one eye.
Branch artery occlusion
• Sudden, painless, partial loss of vision in one eye.
Artery occlusion is diagnosed by examining the retina with an ophthalmoscope.

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