Treatment of intraorbital lesions using the Accuray CyberKnife system.

Purpose: The goal of this study was to better understand the safety and efficacy of CyberKnife image-guided radiosurgery for lesions immediately adjacent to the optic nerves.

Methods: This retrospective, non-comparative, interventional case series included 16 patients (6 women and 10 men) with lesions located wholly within the orbit. Thirteen cases involved tumors (31% benign and 69% malignant), two cases presented with chronic orbital inflammation and one patient had intraorbital tissue growth secondary to Graves disease.

Traumatic globe luxation and enucleation caused by a human bite injury.

A 55-year-old woman presented to the emergency room with complete loss of vision in the left eye after being bit in the face by her autistic grandson. She had a small upper eyelid laceration and an anophthalmic socket on the left side. A thorough history revealed that the bite had caused traumatic luxation of her globe, which had allowed the child to transect the optic nerve with his teeth.

CyberKnife radiosurgery and rituximab in the successful management of sclerosing idiopathic orbital inflammatory disease.

A 26-year-old man presented with symptoms suggesting idiopathic orbital inflammatory disease. After a poor initial response to oral steroids, an orbital biopsy confirmed the diagnosis. A paucicellular lymphocytic infiltrate with areas of fibrosis was seen to replace normal tissue.
