Graves’ eye disease also know as Graves’ ophthalmopathy (GO) occurs when cells from the immune system attack the muscles and other tissues around the eyes. The result is inflammation and a buildup in tissue and fat behind the eye socket, causing the eyeballs to bulge. In rare cases, inflammation is severe enough to compress the optic nerve, causing vision loss.
Other symptoms of GO include:
- dry, irritated eyes
- puffy eyelids and under the eyes
- double vision
- light sensitivity
- pressure or pain in the eyes
- trouble moving the eyes
About 25 percent of people with Graves’ disease develop GO, which is usually of mild to moderate severity. This eye disorder usually lasts 1 to 2 years and often improves on its own. GO can occur before, at the same time as, or after other symptoms of hyperthyroidism develop and may even occur in people whose thyroid function is normal. GO is severe in 3 to 5 percent of people who have the disorder, and smoking makes GO worse.
