Which statement best explains the rationale for careful eye care in Graves' disease with exophthalmos?

• A. The vision will improve immediately with antithyroid drugs alone.
• B. Regular eye lubrication has no effect on discomfort.
• C. Protecting the eyes from irritation helps reduce discomfort.
• D. Eyelid swelling is not related to exophthalmos.

Answer: (C)

In Graves’ disease with exophthalmos, the eyes protrude and may not close fully, leaving the cornea exposed. This exposure dries and irritates the surface, causing discomfort and increasing the risk of keratopathy. Protecting the eyes from irritation and keeping the surface moist directly reduces this irritation, improves comfort, and helps prevent corneal injury. Artificial tears, protective eyewear, shielding from wind or dust, and avoiding rubbing all support this goal and address the immediate eye surface needs.

Systemic control of thyroid activity may help overall disease, but eye symptoms don’t usually improve right away with antithyroid drugs. Eyelid swelling is part of Graves-related eye changes, so focusing on protective care for the ocular surface is the most practical way to relieve discomfort and protect vision.
