Exophthalmos observed on physical examination is most consistent with which condition?

Explanation:
Exophthalmos, or forward bulging of the eyes, is a classic sign of hyperthyroidism, especially Graves disease. In Graves orbitopathy, autoimmune processes target the orbital tissues and extraocular muscles, causing edema and inflammation that push the eyes forward. This makes protrusion a characteristic external finding. The other conditions don’t typically cause this sign: hypothyroidism isn’t associated with eye protrusion; ocular myasthenia gravis mainly causes ptosis and diplopia from weakness of the eye muscles rather than forward eye displacement; cataracts affect lens clarity and vision, not the position of the eyes.
