Walsh & Hoyt: Traumatic Optic Neuropathies: Examination

Visual acuity following indirect optic nerve trauma is often significantly reduced. Each patient in Hughes series of 56 cases presented with no light perception. All 46 patients described by Turner also presented with no light perception on the side with optic nerve injury. In Hoopers series, 14 of 21 patients presented with no light perception. In the series reported by Edmund, 17 of 22 patients presented with no light perception. While vision better than 20/400 is not inconsistent with traumatic optic neuropathy, it is unusual in older reported cases. Pupillary reflexes. Biomicroscopy and fundoscopy.
