Neurological Eye Simulator

 

Ratings

Overall Rating:

5 stars
Content Quality: 5 stars
Effectiveness: 5 stars
Ease of Use: 5 stars
Reviewed: Jul 23, 2002 by Biology Editorial Board
Overview: A simple, but highly effective simulation of the role of the 12 muscles and 6 nerves that control eye movement. The user views the face of the patient while moving the cursor and observing eye movement and pupillary reactions of the left and right eye. Three versions of this module are available from this site. The main difference between v1.4 and v1.5 is the ability to enable and disenable the ptosis feature. Both v1.4 and v1.5 provide an excellent introduction/review on the ?theory page? of the basic involvement of the muscles and nerves controlling eye movement. All versions include a quiz, however,
version 2.0 offers a more comprehensive quiz that compliments a specific case. Three different cases are included in version 2.0. Each case includes patient?s medical history, a physiological examination and neurological testing of eye motion and pupillary responsiveness. Links to the needed Shockwave and Quicktime plugins are provided.
Learning Goals: To learn the involvement of the 12 muscles and 6 nerves that control eye
movement and pupillary responses and, in version 2.0, to learn the appropriate
medical diagnosis and course of action.
Target Student Population: Advanced undergraduate, neuroscience, premed or medical student
Prerequisite Knowledge or Skills: An understanding of eye muscles and cranial nerves is required.
Type of Material: simulation/interactive lesson/tutorial
Recommended Uses: This site could be used in class, for group discussion or as an assigned
tutorial
Technical Requirements: shockwave and quicktime

Evaluation and Observation

Content Quality

Rating: 5 stars
Strengths:

  • The tutorial is challenging for all levels of students
  • Discussion of the quiz answers and the case study discussion for version 2.0
    is a major improvement over version 1.5
  • Very interactive
Concerns:

  • The Theory Page in versions 1.4 and 1.5 are great. The lack of this simple review in version 2.0 is missed.

Potential Effectiveness as a Teaching Tool

Rating: 5 stars
Strengths:

  • The simulation can be used as a stand-alone or classroom exercise.
  • Good quiz feature. The quizzes provide the correct answer (even with an auditory signal of correctness, in version 1.4 and 1.5)
  • Theory page and discussion links provide answers without having to search elsewhere.
  • The ability to control which muscles and nerves are active (or lesioned) enhances the interactive learning feature and thus, enhances the learning potential.
  • The ability to enable ptosis brings the simulation more to life and forces the user to think of pupillary response as a function of cranial nerve III.
Concerns:

  • none

Ease of Use for Both Students and Faculty

Rating: 5 stars
Strengths:

  • Very easy to use and the directions for use are clear
  • Responds quickly
  • Necessary plugins are provided
  • A technical help page is also provided (version 2.0)
Concerns:

  • none
