Research output: Contribution to journalArticlepeer-review

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.
