Area of Science:

  • Ophthalmology and Neuroscience
  • Biomedical Engineering

Background:

  • Noninvasive electrical stimulation (ES) is emerging as a potential therapy for retinal and optic nerve diseases.
  • Current research explores various delivery methods, including transcorneal, transorbital, and transpalpebral approaches.

Purpose of the Study:

  • To review minimally invasive electrical stimulation strategies for vision restoration.
  • To summarize current animal and clinical evidence on transcorneal, transorbital, and transpalpebral ES.
  • To guide future research on optimizing ES for treating vision-impairing diseases.

Main Methods:

  • Literature review of animal experiments and clinical studies on electrical stimulation of the eye.
  • Focus on transcorneal, transorbital, and transpalpebral ES delivery methods.
  • Analysis of proposed underlying mechanisms and observed effects.

Main Results:

  • Animal models show favorable effects of ES on retinal and optic nerve health.
  • Clinical studies indicate promising outcomes, but often lack randomization and control groups.
  • Potential mechanisms include neurotrophic factor production, improved blood flow, and reduced inflammation.

Conclusions:

  • Electrical stimulation (ES) holds potential for vision preservation and restoration.
  • Further research is crucial to understand ES mechanisms and optimize stimulation parameters.
  • Large, prospective, and randomized clinical trials are necessary to validate ES efficacy.
