Third nerve paralysis has been known to be associated with a wide spectrum of presentation and other associated factors such as the presence of ptosis, pupillary involvement, amblyopia, aberrant regeneration, poor bell's phenomenon, superior oblique (SO) overaction, and lateral rectus (LR) contracture. Correction of strabismus due to third nerve palsy can be complex as four out of the six extra...

A case of acute esotropia with bilateral inferior oblique muscle overaction in a 4-year-old boy with a posterior fossa pilocytic astrocytoma is reported. After tumor excision, the esotropia and oblique dysfunction resolved. Acute esotropia with bilateral inferior oblique muscle overaction without abducens palsy is an unusual sign of brain stem mass.

Nasal transposition of the inferior rectus (IR) muscle, which is transposed nasally with the insertion parallel to the spiral of Tillaux, could correct excyclotropia. However, as far as we are aware, there have been no reports examining the surgical effects of this procedure in multiple cases. Therefore, we examined the surgical effects of IR nasal transposition in 135 cases with acquired troch...

We report a patient with partial oculomotor paresis due to midbrain infarction. A 69-year-old man noticed diplopia suddenly. Ptosis, and impaired adduction and supraduction were found in the right eye. The pupillary size and light reflexes were normal on both sides. Magnetic resonance imaging disclosed an acute lesion in the right inferolateral oculomotor fascicle. These clinicoradiological fin...
