Oculomotor Examination – see p. D1eye >>, p. Eye60 >>
external ophthalmoplegia - dysfunction of extraocular muscles, levator palpebrae muscle.
internal ophthalmoplegia - dysfunction of pupillary sphincter muscle, ciliary muscle.
N.B. because both oculosympathetic and oculomotor (parasympathetic) innervation participates in lid elevation, ptosis, if present, generally indicates abnormal eye.
