Objective:

To report a case of unexpected visual recovery in a patient with profound optic nerve damage following cortical microstimulation, highlighting its significance.

Key Findings:

• The patient experienced spontaneous recovery of visual function after nearly four years of blindness.
• Improvements in visual perception occurred with the microelectrode implant switched off, indicating natural vision recovery.
• Electrophysiological assessments showed measurable visual evoked potentials (VEPs) after the intervention, suggesting re-engagement of visual pathways.

Interpretation:

This case challenges the notion of irreversible visual loss and suggests the brain may be a viable target for therapeutic interventions.

Limitations:

• This is a single case report, limiting generalizability.
• The exact mechanisms behind the recovery remain unclear.
• Long-term follow-up data is limited.

Conclusion:

The findings highlight the potential for neuroplasticity in the visual system and may inform future strategies for visual rehabilitation, impacting clinical practice.
