Giant Cell ArteritisWhen an occlusion (blockage of blood vessels) occurs in the eye, the optic nerve can also be affected.

What is the optic nerve?

The optic nerve is considered the back portion of the eye receiving the vision from the retina. Your optic nerve is composed like fiber optic cables receiving and transmitting vision to the visual center in your brain.

How can my optic nerve be affected?

The optic nerve receives its blood supply from the temporal artery. When arteries are affected by swollen blood vessels, the blood supply is hindered causing the optic nerve to starve.

What are some early signs?

Patients may notice a decrease in vision, headache, pain when chewing, or tenderness around their temple/eye area. This may indicate Giant Cell Arteritis (or temporal arteritis).

What tests are performed?

When seeing your Middlesex Eye Physician ophthalmologist, your diagnosis will be confirmed with tests such as blood work, or a temporal artery biopsy.

You will discuss treatment options with your ophthalmologist.
