Neuro-ophthalmologic examination showing ophthalmoplegia affecting the left eye in a patient with Tolosa–Hunt syndrome. The central image represents forward gaze, and each image around it represents gaze in that direction (for example, in the upper left image, the patient looks up and right; the left eye is unable to accomplish this movement). The examination shows ptosis of the left eyelid, exotropia (outward deviation) of the primary look of the left eye, and paresis (weakness) of the third (oculomotor), fourth (trochlear) and sixth (abducens) left cranial nerves. | |

Ophthalmoparesis refers to weakness (-paresis) or paralysis (-plegia) of one or more extraocular muscles which are responsible for eye movements. It is a physical finding in certain neurologic, ophthalmologic, and endocrine disease.
Internal ophthalmoplegia means involvement limited to the pupillary sphincter and ciliary muscle. External ophthalmoplegia refers to involvement of only the extraocular muscles. Complete ophthalmoplegia indicates involvement of both.
