Which statement about Thyroid Eye Disease is true?

Which statement about Thyroid Eye Disease is true?

• A. It never affects the optic nerve
• B. It commonly occurs in nonsmokers
• C. It is commonly associated with smoking and can cause protrusion of the eyes
• D. It is a purely superficial eyelid condition

Answer: (C)

Thyroid Eye Disease is an autoimmune inflammation of the orbit, most often linked to Graves' disease. The swelling of extraocular muscles and orbital fat increases the contents’ volume within the bony orbit, pushing the eye forward (proptosis) and potentially causing double vision from restricted eye movements. Smoking is a major risk factor and is associated with more severe disease and greater proptosis; this makes the statement describing a strong link to smoking and eye protrusion accurate. It’s not confined to the eyelids—it involves deeper orbital tissues and can even threaten the optic nerve in more severe cases due to compression or edema. So, the statement that it is commonly associated with smoking and can cause protrusion of the eyes is the true one. The other descriptions don’t fit because the condition can affect the optic nerve in severe cases, and it commonly occurs in smokers rather than nonsmokers, and it is not merely a superficial eyelid issue.
