Relation of NDC with retinal thickness and visual field defect*
- Preserved local processing — similar building dwell times
- Reduced global visual exploration — lower gaze-network connectivity
- Consistency with reduced scanning
- pRNFL–NDC relationship — retinal damage linked to gaze organization
- Extension from laboratory visual search to naturalistic VR navigation
