Area of Science:

  • Medical Education Technology
  • Ophthalmology
  • Neuroscience

Background:

  • Neurological examinations assess cranial nerves II, III, IV, and VI via eye assessments.
  • Medical students face challenges interpreting ophthalmic signs due to infrequent patient encounters.
  • A need exists for a simulator to practice ophthalmic responses in various neurological conditions.

Purpose of the Study:

  • To design and develop an ophthalmic response simulator (EyeSim) for medical training.
  • To create a tool that replicates typical and atypical ophthalmic responses.
  • To augment neurological examination teaching practices in medical schools.

Main Methods:

  • Developed electrical, electronic, and mechanical components for pupillary response and ocular motility.

Related Experiment Videos

  • Integrated a computer for video signal reception and analysis.
  • Utilized micro-controller components to modulate physical responses based on inputs.

    • Main Results:

    • The EyeSim simulator can track pen-torch movements and adjust iris dilation based on light.
    • Responses are modulated to simulate deficits caused by neural pathologies.
    • The system integrates hardware and software for realistic ophthalmic response simulation.

    Conclusions:

    • The developed ophthalmic response simulator effectively replicates key ophthalmic signs.
    • EyeSim can serve as a valuable standalone teaching tool or be integrated into high-fidelity mannequins.
    • This technology enhances medical student training in neurological examinations.
