Neuro-Ophthalmology & Neuro-Otology
Combined third, fourth, and sixth nerve palsies
By definition, multiple ocular motor palsies are present when eye muscle weakness, with or without anisocoria and ptosis, indicates dysfunction of more than one ocular motor nerve. The cardinal symptom is binocular diplopia, ie, double vision only when both eyes are open. Ophthalmoplegia caused by multiple ocular motor nerve palsies must be differentiated from that caused by single ocular motor nerve palsies, supranuclear gaze disorders, neuromuscular junction disorders, and myopathy.
