Abstract: Peripheral visual field defects, as a common manifestation of various ophthalmic and neurological disorders, significantly impair patients' visual function and quality of life. In recent years, perceptual learning based on visual cortical plasticity has demonstrated the potential to activate residual visual function, improve visual sensitivity, spatial integration, and visual search ability, thereby promoting visual field recovery and functional enhancement. Moreover, intelligent devices have enabled diversified training modalities. Specifically, computer-based training enhances fine visual discrimination, oculomotor control, and spatial perception through tasks involving stimulus recognition, eye movement, and visual attention with spatial cueing; virtual reality-based training improves binocular visual field perception; and multimodal training with auditory and neurofeedback further strengthens overall sensitivity and multisensory integration. These training modalities collectively provide novel theoretical foundations and application pathways for visual rehabilitation in peripheral visual field defects.
