6 Eye Signs of Hyperthyroidism
Hyperthyroidism is a condition in which the thyroid gland produces too much of the thyroid hormone, causing symptoms like weight loss, irregular heartbeat, hand tremors, and more. Hyperthyroidism can also result in symptoms that affect the eyes in a variety of ways. Luckily, if this condition impacts the eyes there are a few treatments that can help, including infusion therapy, corticosteroids, orbital radiotherapy, and eyelid retraction repair. If you’re worried you may have hyperthyroidism, here are 6 eye symptoms and signs to look out for: 1. Eyelid retraction Eyelid retraction is the most common eye sign of hyperthyroidism. This can be attributed to increased stimulation of the Muller’s muscle, which functions to keep elevation of the upper eyelid, by the thyroid hormone. It could also potentially be caused by scar tissue forming between the muscles and tissue around the eye. 2. Dry and gritty feeling With hyperthyroidism, your eyes may experience a dry and gritty feeling that is itchy and scratchy—this is due to the inflammation of the tissues surrounding the eyes. The constant pressure of the inflammation is what causes the strange sensation and may also result in redness and swelling. You may want to speak to your doctor about getting eye drops.
