This course is broken down into weeks and each week consists of one in- depth power point lecture, often with additional readings that you will receive in advance. Typically this is a 2 hours in-class delivery, so plan on committing that much time per week for the read- through to review. You will be provided a written copy of the lectures, also you will view the lectures on the internet (through your email) as printed-out versions could lack some detail.

 

There is an additional assigned weekly 2-hour laboratory component in which to practice the skills taught in lectures. I would suggest you set aside at least this amount of time each week, in addition to the lectures, to practice your skills.

 

To aid you in your practice and help you learn proper examination techniques, you will be given a skills booklet in which to record your practice under observation. For each skill you will find a check-off list of things to remember when you are performing each task, and these are the things your proctor will be looking for as well. You will be required to have a proctor observe your performance, sign the corresponding page in the practice booklet confirming that you have been performing the task properly, and deliver it to me within the designated time frame (see calendar for exact weeks that these are due).

 

Other forms of evaluation include assignments, discussion questions, and written exams. Please read on for details...

 

Course Content:

 

This class will introduce the student to the complexities of analysis of the visual system. The course is designed to teach the optometry student the methods treatment of binocular problems emanating from visual and oculo-motor inefficiency. This will be achieved through clinical scenarios in which the student wilt be required to engage in direct patient care, including sensory visual evaluation, physical ocular assessment, and biomedical application of ophthalmic instrumentation as well as the treatment of binocular vision anomalies including those conditions which result in a reduction of visual efficiency (phorias, decreased vergence facility) and conditions which result in decreased binocular function (amblyopia and strabismus). The treatment of other visual and oculo-motor problems such as deficit of pursuit, saccades and eye-hand coordination will also be discussed. Afferent System will normally be taken either prior to, or concurrently with, this class.

 

Objectives:

 

This class will provide the student with the knowledge and experience specific to normal binocular vision so that the student will show the following understanding and abilities:

 

1. Understand the abnormality and method of treatment for: strabismus, saccade, pursuit convergence, divergence and vergence range problems.

 

2. Understand the treatment of other visual and oculo-motor problems such as deficit of pursuit, saccades and eye-hand coordination

 

3. The ability to select and administrate diagnostic tools to evaluate binocular status and identify anomalies in a patient scenario.

 

4. The ability to determine the appropriate sequence and application of tests for sensory visual evaluation and physical ocular assessment, based on the findings of ophthalmic examination.

 

5. Think and act logically following standardized testing methods to provide the highest quality of patient care.

 

6. Identify testing procedures considered necessary for each orthoptic patient where the patient’s age, mental, physical and emotional capability will permit such testing

B. By the start of the course you would receive:

 

1. Weekly printed copies of lectures,

2. Accompanying readings for each lecture,

3. Course outline, calendar, etc.

4. Practical Skills Booklet

 

Continuous Assessments:

 

There will be 1 continuous assessment tests (written exam) during the course of this semester. It will be in the form of multiple-choice and short answer quizzes during the lecture periods or short essays on topics already covered. Other forms of evaluation include assignments, class's discussion questions, and written exams. Please read on for details...

 

Course Evaluation:

 

1.     Assignment (10%)

2.     In class participation (5%)

3.     Practical Skills Booklet (20%)

4.     Midterm Exam (25%)

5.     Final Exam (40%)

 

Detailed Course Evaluation by Component:

 

1- Assignment (10%)

 

Please find the assignment section of your course and you will see that you have (Assignment #1) due at the end of the course. This involves an APA style research paper that is sent to the entire class. It will be from this research that you will study this topic and no other lectures will be provided. Please see me for more details.

 

2- In class participation (5%)

 

3- Practical Skills Booklet (20%)

 

Weekly (will be indicated in the course calendar and course summary by weeks), we will clinically practice the course assigned clinical examinations. These sections are designed to explore the practical content of the class and develop your clinical skills. You are required to participate as well as completing and returned the checklist with the Skills Objective Achievement Sheet you have received earlier (Assignment #2). All completed practical skills booklet forms must be submitted by the required due date. Your participation in the practical section as well as completing your assignments will greatly impact your clinical participation grade for the course. Please review the practical skills booklet for more detail.

 

4-Midterm Exam (25%)

 

This will be a short answer and multiple-choice test to be completed within 2 hours under the supervision of a proctor. This exam will be sent to your proctor and they will administer it and then send it to me for grading.

 

5-Final Written Exam (40%)

 

Similar to the midterm, but usually requires 3 hours to complete and includes all course material.

 

Please Note: Examinations must be written during allotted times and make- ups will be permitted only due to illness or other very exceptional circumstances. You must notify me before the scheduled exam if you will be absent. A physician’s medical report dated that day of the missed examination will be necessary to document legitimate illness.

Late assignments will be accepted with the following penalties:

1 day late10% penalty

2 days kite20% penalty

3 days late 30% penalty and so on....
