Targeted Shortwave Diathermy Combined With Perceptual Training for Patients With Severe Traumatic Optic Neuropathy

Purpose: Patients with severe traumatic optic neuropathy (TON) have limited improvement in visual function despite therapy. The hypothesis of the study is that the targeted shortwave diathermy combined with perceptual training may enhance visual function in patients with severe TON after endoscopic optic nerve decompression (EOND) surgery. Design: Clinical trial Subjects: Twenty-two subjects with severe TON after EOND surgery were randomly assigned to either a rehabilitation (Reh) group or nonrehabilitation (Nreh) group. Methods: High-resolution computed tomography and MRI were used to locate the impaired nerve. The subjects in the Reh group received targeted shortwave diathermy therapy 5 days per week for 4 weeks and perceptual training 5 days per week for 10 weeks. Main Outcome Measures: A thorough evaluation of visual function, visual evoked potential, and diffusion tensor imaging was executed.
