[X-ray computed tomography in surgical indication of physiological section of the optic nerve. Apropos of 15 cases].
Optic nerve trauma induces loss of vision and absence of direct pupillary light reflex. Persistence of consensual pupillary light reflex excludes anatomical section. Trans ethmoidal-sphenoidal decompression relieves the optic nerve and allows an improvement of visual function. Ten patients among 15 surgical decompressions recovered visual function. There is a good correlation between improvement and the release of an anatomical nerve compression. Recognition of direct or indirect computed tomographic signs of optic nerve compression are essential in the surgical indications. The prognosis post-surgical improvement is dependent on the sensitivity of computed tomography scan.
