Step-by-step explanation:
What Does "Exophthalmos (Protruding Eyes)" Refer To?
Exophthalmos, also known as protruding eyes, is a condition where the eyes bulge outward beyond their normal position. This condition is often associated with Graves' disease, which is an autoimmune disorder that leads to the overactivity of the thyroid gland, known as hyperthyroidism. One of the signs of this thyroid dysfunction is protruding eyes, as mentioned in Figure 12.5.5 and Figure 19.14. Moreover, exophthalmia or Graves ophthalmopathy is considered a hallmark sign of Graves' disease.
Another thyroid-related condition that can affect the eyes is exophthalmic goiter, which involves the bulging of the eyeballs. This can be due to various factors, including an iodine deficiency, thyroid tumors, excess production of Thyroid Stimulating Hormone (TSH), or Long-acting Thyroid Stimulator (LATS). The thyroid system and its abnormalities, including conditions like proptosis and lid retraction from Graves' disease, are important components of understanding the endocrine system and its pathologies.
Therefore, the correct answer to the question “What does "Exophthalmos (Protruding Eyes)" refer to?” is B) Protruding eyes.
