Options

A. Myxoedema
B. Simple goiter
C. Exophthalmos
D. Acromegaly

Answer

**Step-by-Step Solution:**

1. **Understanding the Condition**: The question refers to a specific condition that occurs as a result of hyperthyroidism, which is an overproduction of thyroid hormones. This condition can lead to various symptoms, including swelling behind the eyes.

2. **Identifying the Symptoms**: In hyperthyroidism, one of the notable symptoms is the protrusion of the eyeballs, which is often accompanied by swelling and retraction of the eyelids. This is due to the accumulation of fat and inflammation in the eye muscles.

3. **Recognizing the Medical Term**: The medical term for the swelling or protrusion of the eyes due to hyperthyroidism is known as "exophthalmos." This term specifically describes the bulging of the eyes.

4. **Differentiating from Other Options**: The question provides several options:
- Myxedema: This is associated with hypothyroidism, not hyperthyroidism.
- Simple goiter: This refers to an enlargement of the thyroid gland but does not specifically relate to eye symptoms.
- Acromegaly: This condition is caused by excess growth hormone and does not involve the eyes in the same way.

5. **Conclusion**: Based on the understanding of hyperthyroidism and its effects on the eyes, the correct answer to the question is "exophthalmos."

**Final Answer**: Exophthalmos
