Lagophthalmos: an unusual manifestation of oculomotor nerve aberrant regeneration
1Department of Ophthalmology and Visual Sciences, Washington University, St. Louis, Missouri, USA.
Purpose:
To describe a patient with unusual findings after regeneration of the oculomotor nerve.
Methods:
Case report.
Results:
A 35-year-old woman developed complete right third nerve paralysis after neurosurgical ligation of internal carotid-posterior communicating and internal carotid-ophthalmic artery aneurysms. Permanent ipsilateral lagophthalmos appeared as third nerve function spontaneously recovered.
Conclusion:
Lagophthalmos may rarely develop after aberrant regeneration of the oculomotor nerve, presumably caused by co-contraction of the levator and superior rectus muscles during the Bell's phenomenon.
