Transcranial approach for treatment for traumatic optic chiasm syndrome

Abstract

To describe the visual outcome of patients with a traumatic optic chiasm syndrome, with and without neurosurgical intervention. The retrospective clinical interventional study included 14 patients, who either underwent a neurosurgical intervention with transcranial decompression of the optic canal (11 patients) in combination with a high-dosage systemic corticosteroid therapy or who received a high-dosage systemic corticosteroid tretament only (3 patients). In the surgical group, visual field improved after surgery in 6 (55%) patients and remained unchanged in 5 (45%) patients, while in none of the patients without surgery, the visual field improved. Neurosurgical decompression of the optic chiasm and optic nerve canal may be associated with a visual improvement in some patients with a traumatic optic chiasm syndrome.

Comment

In this report 14 patients were treated for post-traumatic loss of vision that was attributed to a chiasmatic damage either by surgery (n = 11) or steroids (n = 3). The timing of the operations after the trauma varied considerably between 8 and 120 days (mean: 41 days). Recovery of vision was better in the surgical group. Interestingly, visual acuity improved in every patient in this series. 6 out of 12 operated patients also had an improvement of visual fields. Whether the post-traumatic deterioration of vision is due to damage of optic nerves or chiasm is difficult to determine.
