Amaurosis secondary to frontal traumatism. Arch Soc Esp Oftalmol [online]. 2006, vol.81, n.2, pp.115-118. ISSN 0365-6691.

Case report: We present the case of a patient diagnosed with amaurosis of the right eye secondary to a right frontal contusion. The energy of the impact was projected from the orbital ceiling to the minor wing of the sphenoid bone. This bone was fractured, thus reducing the optic canal diameter and damaging the optic nerve. Discussion: In our case, we describe a mixed mechanism of injury, that is to say, a frontal contusion indirectly transmitted to the optic canal and a direct lesion of the optic nerve secondary to the movement of the minor wing of the sphenoid bone into the optic canal.
