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.
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:
This site could be used in class, for group discussion or as an assigned tutorial
shockwave and quicktime
Evaluation and Observation
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
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
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.
Ease of Use for Both Students and Faculty
Very easy to use and the directions for use are clear
Necessary plugins are provided
A technical help page is also provided (version 2.0)
