A Case of Orbital Apex Syndrome Caused by Paranasal Sinusitis / 대한이비인후과학회지

ABSTRACT

Acute visual loss may occur in association with sinusitis either as a complication of orbital cellulitis or, less frequently, as a part of the orbital apex syndrome. Originally, an orbital apex syndrome is associated with an affection of the vessels and nerves passing through the superior orbital fissure and the optic foramen. A classical feature of orbital apex syndrome is presented with visual loss and ophthalmoplegia, but with minimal or no signs of orbital inflammation such as proptosis, chemosis, or lid edema. We present a case of male patient with alternating bilateral visual loss with ophthalmoplegia secondary to paranasal sinusitis.
