Abstract
|
|
|
A sudden monocular blindness following the blunt trauma around the orbit is not new. However, the nature of the lesion did not surface until 1845, when Nuhn suggested that the optic nerve might be the site of the lesion.
The optic nerve injury is caused by stretching, tearing, torsion, contusion of the optic nerve or ophthalmic artery, or by skeletal distortion with hematoma which compressed the nutrient vessel and verve.
Decompression of the optic nerve was thought to be the most effective treatment. Clinical and experimental studies show the advantage of steroids in reducing traumatically induced CNS damage, so the use of megadose steroids should be beneficial in reducing microcirculatory spasm, edema and nerve cell necrosis. Anatomically distrubed optic canal was decompressed with surgical intervention for improvement of visual acuity.
Blindness following the blunt trauma will be prevented by immediate and active management as surgical intervention and/or megadose steroids.
