Course DescriptionExplores ocular motility, associated testing and measurements required for evaluation. Emphases understanding the presentation, characteristics and history of the strabismus patient. Discusses amblyopia treatment and therapies. Audit available.
Intended Outcomes for the course
1. Effectively evaluate patients for the presence of phorias and tropias.
2. Measure ocular deviations with prisms in the clinic setting.
3. Properly identify pathological conditions that manifest with ocular deviations in the clinic setting.
4. Accurately screen patients for ocular muscle imbalances in the clinic setting.
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.
