Superior orbital fissure syndrome. Review of 130 cases.

Superior orbital fissure syndrome is a symptomatologic complex, consisting of retroorbital pain, paralysis of extraocular muscles, impairment of first trigeminal branches and frequent involvement of the optic nerve. From a review of 130 published cases including two personal observations, it appears that the clinical subdivisions and the several eponymic differentiations of this syndrome are unjustified on the basis of etiologic, therapeutic and prognostic elements. Only the presence--or absence--of optic signs may allow to hold the clinically useful distinction between the often 'benign' superior orbital fissure syndrome without optic nerve involvement, and the orbital apex syndrome where orbital exploration may be recommended. This review concludes that repeated neurosurgical and neuroradiologic investigations--with the exceptions of carotid angiography and orbital phlebography--can be avoided in such cases.
