Question

Quizplus · Accepted Answer

Exophthalmos is a condition that results in the abnormal protrusion of the eyeball from the orbit due to an overproduction of thyroid-stimulating hormone (TSH) by the thyroid gland. The excess TSH causes an increase in the production of T₃ and T₄, which leads to an enlargement of the muscles and tissues behind the eyes, pushing them forward and causing the eyes to bulge out.
