Horner's syndrome consists of -: (A) Miosis and enophthalmos, (B) Miosis and exophthalmos, (C) Miosis and proptosis, (D) Miosis and ptosis
Answer is D. Horner's syndrome is characterized by classical triad of ipsilateral ptosis, miosis and anhydrosis.
Option 'a' is also correct as enophthalmos also occurs. However, it is not included in the classical triad of Homer's syndrome. So, best answer here is option 'd'.
