A case of visual loss following cranio-maxillofacial trauma is reported. The patient had a sudden partial blindness associated with a fracture of the roof, medial and lateral orbital walls. Access to the orbit was achieved through a transethmoidal approach using the Howarth-Lynch medial incision and resecting the bone fragments which impinged on the optic nerve. The patient had total return of visual acuity, without surgical complications. The role of orbital and optic decompression in the management of patients with traumatic optic neuropathy is discussed. Its indications are controversial and the procedure should be considered only within the context of the specific needs of the individual patient.

UI	MeSH Term	Description	Entries
D009900	Optic Nerve	The 2nd cranial nerve which conveys visual information from the RETINA to the brain. The nerve carries the axons of the RETINAL GANGLION CELLS which sort at the OPTIC CHIASM and continue via the OPTIC TRACTS to the brain. The largest projection is to the lateral geniculate nuclei; other targets include the SUPERIOR COLLICULI and the SUPRACHIASMATIC NUCLEI. Though known as the second cranial nerve, it is considered part of the CENTRAL NERVOUS SYSTEM.

D001766	Blindness	The inability to see or the loss or absence of perception of visual stimuli. This condition may be the result of EYE DISEASES; OPTIC NERVE DISEASES; OPTIC CHIASM diseases; or BRAIN DISEASES affecting the VISUAL PATHWAYS or OCCIPITAL LOBE.

D014792	Visual Acuity	Clarity or sharpness of OCULAR VISION or the ability of the eye to see fine details. Visual acuity depends on the functions of RETINA, neuronal transmission, and the interpretative ability of the brain. Normal visual acuity is expressed as 20/20 indicating that one can see at 20 feet what should normally be seen at that distance. Visual acuity can also be influenced by brightness, color, and contrast.	Acuities, Visual,Acuity, Visual,Visual Acuities
