Course Description

Explores ocular motility, associated testing and measurements required for evaluation. Emphasizes understanding the presentation, characteristics and history of the strabismus patient. Discusses amblyopia treatment and therapies. Prerequisites: (WR 115 and RD 115) or IRW 115 and MTH 20 or equivalent placement, and admission to the OMT Program or Program Director approval. Audit available.

Intended Outcomes for the course

Upon successful completion of the course students should be able to:

1. Effectively evaluate patients for the presence of phorias and tropias.
2. Measure ocular deviations with prisms.
3. Identify pathological conditions that manifest with ocular deviations.
4. Evaluate patients for ocular muscle imbalances.

Course Activities and Design

The class will be presented by means of lecture/discussion, audio-visual presentations, handouts and demonstrations. Guest speakers and field trips may be utilized by the instructor as a means of assisting the student in mastering course goals and objectives.

Outcome Assessment Strategies

At the beginning of the course, the instructor will detail the methods used to evaluate student progress and the criteria for assigning a course grade. The methods may include one or more of the following tools: examinations, quizzes, homework assignments, research papers.
