Final answer:
Exophthalmos, or bulging eyes, is an indication of Graves' disease, a condition associated with hyperthyroidism.

Other symptoms of Graves' disease include rapid and irregular heartbeat, weight loss, heat intolerance, and goiter.
Step-by-step explanation:
Exophthalmos, or bulging eyes, is an indication of Graves' disease. It is a condition associated with hyperthyroidism, where the thyroid gland produces too much thyroid hormone. Other symptoms of Graves' disease include rapid and irregular heartbeat, weight loss, heat intolerance, and goiter (a swollen thyroid gland). Exophthalmos is caused by an abnormal accumulation of fluid and tissue behind the eyes, which leads to their protrusion.
