OPT 316
Physiological Optics II
1 Unit(s) (LH 15)
Course Description
At the end of OPT 316 (Physiological Optics II) course, students should be able to:
1. describe the basic electrical activities associated with the extraocular muscles and their nerve
supply;
2. identify the contribution(s) of the various extraocular muscles to the optics of the eye with
respect to their origins, insertions, and actions;
3. explain the physiology behind the optical changes that occurs during accommodation;
4. explain the role of vergence movements in the optics of the eye and the different components
of vergence;
5. explain the relationship between accommodation and convergence in the form of the AC/A
ratio;
6. explain the role of versional movements in the optics of the eye and the different forms of
version movement;
7. describe retinal disparity and the effects it has on the optics of the eye;
8. describe fusion and the effects it has on the optics of the eye;
9. describe the different forms of fixation pattern and their effects on the optics of the eye;
10. explain all that is involved in binocular coordination; and
11. describe the Horopter, Panum’s Fusional Area, Phoria, and Tropia.
Course Outline
The extra-ocular muscles, their electrophysiology, actions, and innervation. Accommodation,
convergence, the AC/A ratio and binocular co-ordination. Fusion, fusional vergence, retinal
disparities and the horopter. Laboratory work is included.
