Oculomotor nerve palsy often presents with which of the following?

• A. Ptosis
• B. Vertical diplopia
• C. Headaches
• D. Loss of smell

Answer: (A)

Oculomotor nerve palsy is characterized by a variety of symptoms, primarily due to the disruption of motor function to several extraocular muscles that control eye movement. One of the hallmark signs of this condition is ptosis, which is the drooping of the upper eyelid. This occurs because the levator palpebrae superioris muscle, responsible for elevating the eyelid, is innervated by the oculomotor nerve. When the nerve is affected, this muscle can no longer function properly, leading to a noticeable droop in the affected eyelid. In addition to ptosis, patients with oculomotor nerve palsy may also experience other symptoms such as diplopia (double vision), particularly vertical diplopia, resulting from misalignment of the eyes due to the paralysis of the extraocular muscles. However, ptosis is specifically prominent as a direct result of the nerve's involvement with muscle function. Headaches can occur in some cases, but they are not a defining feature of oculomotor nerve palsy itself. Loss of smell is unrelated to the functions of the oculomotor nerve, as it pertains to the olfactory nerve. Thus, ptosis stands out as the most characteristic symptom associated with o
