There is a disease called giant cell arteritis or temporal arteritis. It is a condition which causes inflammation of blood vessels. Sometimes, inflammation can affect the blood vessels supplying the eye. If this happens permanent vision loss can occur. Common symptoms associated with giant cell arteritis or temporal arteritis may include headache, scalp tenderness, discomfort when chewing, eye pain or vision loss. There are blood tests that can suggest giant cell arteritis, but the diagnosis typically requires examination of an artery under the microscope.
