Role of visual evoked potential (VEP) in indirect traumatic optic nerve (ITON) injuries and assessment of the visual outcome

Abstract

To demonstrate the critical function of Visually Evoked Potential (VEP) in the prompt detection of indirect optic neuropathy. 60 patients suspected of having traumatic optic nerve injury underwent VEP testing in < eight hours of traumatic experience. Baseline visual acuity was revealed to be the most imperative prognosticator of eventual visual outcome. The VEP was instrumental in the primary detection as well as validation of ITON. Additionally, VEP aided in predicting prognosis and follow-up for patients with IITON. Visual recovery is impossible in the absence of recordable VEP waves. The manifestation of orbital fractures wasn't associated with a preliminary or ultimate visual perception decrease. Patients who present < 8 hours following ITON with normal initial visual acuity, VEP alterations, and lower RAPD grades may have a greater chance of recovering final visual perception when treated with an instantaneous high steroid dosage. The above-mentioned prognostic markers in patients with ITON may be beneficial in predicting visual prognosis and determining the need for surgical therapy in patients who experience vision loss following head trauma.
