10 Hyperthyroidism Symptoms
Reviewed: Dr. Mera
Symptom #9: Protruding Eyes
In some cases of hyperthyroidism, the eyes can protrude. Medically, this is known as exophthalmos where the eye bulges anteriorly out of the orbit. In hyperthyroidism, it is often bilateral. It can also be seen in other conditions but is usually unilateral in these cases.
If untreated, it can lead to the failure of the eyelids to close completely over the eyes leading to dryness and damage of the cornea. Thyroid eye disease is also known as Grave’s ophthalmopathy. It should be treated as soon as possible as the optic nerve can be affected leading to permanent damage to sight.
