Orbital Apex Syndrome Caused by Intraorbital Aspergillus Infection.

Orbital apex syndrome, a clinical disease that is uncommon and has a high fatality rate. Tumor, endocrine, and inflammatory variables are frequently responsible for its occurrence. The authors describe a 53-year-old Chinese man who was diagnosed with orbital apex syndrome and coupled type 2 diabetes mellitus and a fungus infestation. Treatment included nasal endoscopic orbital apical decompression, anti-infection, and adequate debridement. Except for inevitable optic nerve damage, postoperative proptosis and headache manifestations improved, and systemic infection was timely contained with no signs of recurrence or serious complications occurred. The orbital apex syndrome is difficult to treat, and soon as possible biopsy of the lesion, aggressive surgical decompression, and antifungal treatment seem to be effective ways to improve survival rates.
