Central Retinal Vein Occlusion Causes

Retinal vein occlusions generally occur because your arteries harden and cause a clot, much like a stroke. Blockages are more common in individual with narrowed or damaged blood vessels, or those with constant conditions that cause them. Such central retinal vein occlusion causes include:

  • People who smoke
  • High blood pressure
  • Diabetes
  • Atherosclerosis, which is a hardening of the arteries
  • High cholesterol
  • People over the age of 60
  • Glaucoma, which is optic nerve damage that’s usually caused by increased pressure
  • Blood disorders that affect clotting
  • Macular edema, which is fluid leakage into the macula, or the area of the retina that allows for sharp focus

Because retinal vein occlusion occurs in veins, you can reduce your risk of it by protecting your blood vessels and maintaining healthy vascular tissue. Treatment for Retinal Vein Occlusion focuses on issues arising from the occlusion, such as

  • Losing weight if you’re overweight
  • Exercising
  • Maintaining a healthy weight
  • Controlling diabetes if you have diabetes
  • Quitting smoking if you smoke
  • Reducing your cholesterol if you have high cholesterol
  • Reducing your blood pressure if you have high blood pressure
  • Taking aspirin or other blood thinners if suggested by your doctor
