EXAMINATION THE ROLE OF VISUAL EVOKED POTENTIAL IN DIAGNOSIS AND PROGNOSIS OF TRAUMATIC OPTIC NEUROPATHY
Main Article Content
Abstract
Purpose: To assess the value of visual evoked potentials (VEPs) in diagnosing optic nerve injury and predicting visual recovery in patients with traumatic optic neuropathy. Method: A prospective observational study was conducted on 29 patients aged 18 to 60 years with traumatic optic neuropathy, in whom PVEP and FVEP were measured at Military Hospital 175. Result: Compared to the unaffected eyes, the traumatized eyes showed significantly reduced amplitudes and prolonged latencies of both PVEP and FVEP. There was a moderate to strong positive correlation between the initial PVEP (r = 0.575) and FVEP (r = 0.603) amplitudes and visual acuity at 8 weeks post-injury, demonstrating the prognostic value of visual evoked potentials. Conclusion: Visual evoked potential (VEP) is an objective and clinically meaningful tool for evaluating optic nerve injury and predicting visual recovery in traumatic optic neuropathy. Both PVEP and FVEP are valuable and can be flexibly applied depending on the clinical context.
