Unilateral acquired upper eyelid ptosis and decreasing nystagmus.

Abstract

To describe a patient with congenital nystagmus that decreased in one eye after the development of a cavernous sinus meningioma. Interventional case report. A 45-year-old man with congenital nystagmus, albinism, and high myopia presented with right upper eyelid ptosis that was corrected surgically on three occasions during a 3-year period. An episode of syncope was followed by diagnostic evaluation that disclosed a cavernous sinus meningioma. He commented that his right eye nystagmus progressively decreased. He was found to have ophthalmoplegia on the right eye due to nerve compression by the meningioma. A magnetic resonance imaging scan disclosed a cavernous sinus meningioma extending into the parachiasmal and clival areas. A biopsy specimen of the lesion demonstrated a meningioma. Any patient with acquired ptosis should have a complete ophthalmic examination, including evaluation of extraocular motility.
