Graves’ eye disease (ophthalmopathy) doesn’t necessarily have anything to do with the thyroid levels at all. It must be treated separately. Be sure and get her checked by an Ophthalmologist to keep track of the condition of her eye, and watch for future problems.
Most people with Graves’ don’t get the severe eye problems but some of us really get whacked by it. It is not just a cosmetic problem and secondary glaucoma and nerve damage are possible.
She may have no problems with vision, and yet it is postentially very serious. I was blinded by it for over a year & I have no thyroid problems.
