Sekundäre Erblindung nach orbitaler Holzfremdkörperverletzung

Abstract

We report a 68-year-old male who had orbital trauma from a bicycle accident. His vision was initially normal but deteriorated over 8 days to complete blindness. After 13 days, when he first consulted a physician, clinical investigation revealed total ophthalmoplegia, ptosis, and chemosis. Computed tomographic scan showed fractures of the medial orbital wall, orbital floor, and posterior ethmoid with dislocation into the orbital apex near the optic nerve. The patient was sent to our department for optic nerve decompression. Clinical examination showed induration and an already healed infraorbital entry wound suggesting an orbital foreign body, which was confirmed by ultrasound. Renewed analysis of CT scans in different window settings could clearly demonstrate a wooden foreign body in the lower eyelid. Additionally, a diffuse inflammation in the orbital apex was diagnosed. The foreign body was removed and decompression of the orbita and optic nerve was performed. Antibiotics and corticosteroids were administered i.v. Unfortunately, no visual improvement could be achieved.
