Symptoms of Ischaemic Optic Neuropathy

Vision loss can be fast (in days, hours or even minutes sometimes), and is not associated with eye pain.

Depending on the cause, the vision can be damaged in one eye or both. Vision in the affected eye can range from being almost normal to being completely blind. In the beginning, a small area of loss of vision usually appears in the centre of the visual field, which slowly enlarges and can develop to complete blindness.

People with giant cell arteritis are usually elderly, and their loss of vision tends to be more serious. They can suffer pain when chewing, headaches, pain and muscle discomfort and pain while combing their hair.
