5 Key Takeaways

• 1

  Acquired ocular motor palsies of cranial nerves III, IV, or VI often indicate underlying systemic or neurologic disorders.

• 2

  Diplopia is the most common symptom of ocular motor palsies, requiring differentiation between binocular and monocular types for accurate diagnosis.

• 3

  A comprehensive assessment of ocular alignment and motility is essential, as subtle paresis can be missed without thorough testing.

• 4

  Cranial nerve palsies present characteristic patterns of deviation, with specific signs indicating potential serious conditions like aneurysms.

• 5

  Associated neurologic function should be assessed to narrow differential diagnoses and determine the urgency of systemic workup.
