									                                   Course Outline

Course Title OPTO 375: Anomalies of Binocular Vision
Instructor: Safiah Mulla MSc, BSc, OC(C)
King Saud University
College of Applied Medical Science
Optometry Department
Telephone: 01-4355010 Ext: 883

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 takes about 2 hours for the in-class delivery, so plan on committing that much time
per week for the first read- through. I will provided you with a written copy of the
lectures, but please also view the lectures on the internet (via your email).

There is an additional recommended weekly 2-hour laboratory component in which to
practice the skills taught in lectures, to practice your skills.
To aid you in your practice and help you learn proper examination techniques, you will
be given a practical 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
Other forms of evaluation include assignments, discussion questions, and written and
practical exams. Please read on for details...

Course Content
This class will introduce the student to the complexities of analysis of the anomalies of
BSV system. This will be achieved through clinical scenarios in which the student will be
required to engage in direct patient care, including sensory visual evaluation, motor
visual evaluation. This class is a prerequisite for OPTO 493 Orthoptics

This class will provide the student with the knowledge and experience specific to
abnormal binocular vision so that the student will show the following understanding and
1. The ability to select and administrate diagnostic tools to evaluate binocular status and
identify anomalies in a patient scenario.
2. The ability to determine the appropriate sequence and application of tests for sensory
fusion evaluation, based on the findings of ophthalmic examination.

3. Knowledge of the sensitivity and specificity of the array of visual- function tests
presented in this class.
4. The capability and proficiency required to meet clinical standards of ophthalmic
medical technology.

Course Material
1. By the Start of the course you will receive the following:

     a. Course outline, calendar, etc.
     b. Skills Booklet c.
     c. Weekly printed copies of lectures, accompanying readings for each lecture,

Course Evaluation:
         1.   Synoptophore Assignment (5%)
         2.   Practical Skills Booklet (20%)
         3.   Midterm Exam (25%)
         4.   Final Exam (50%)

Detailed Course Evaluation by Component:

1- Synoptophore Assignment (5%)

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- 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.

3-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.

4-Final Written Exam (50%)

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

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....

1. Cortical suppression is very selective because:

      A.   it develops only in young children
      B.   it allows light discrimination of function normally
      C.   it is confined to macular Para macular areas
      D.   it is confined to the photopic visual state

2. Which of the following may be used to test for suppression?

      A.   biological motion
      B.   Bonferroni prisms
      C.   DaVinci stereoscope
      D.   Bagolini lenses

3. Using Bagolini filter to test the relative depth of suppression, you find
that OS is suppressed using a 1.0 ND filter, but OD is suppressed using
a 2.0 ND filter. Based on this, which eye is probably the sensory
dominant eye?

      A.   OD
      B.   OS
      C.   Either eye is equally likely to be the dominant eye.
      D.   Not enough information. It will depend on the results of a
           directional dominance test.

4. Compensating for double vision by ignoring the image from the
deviating eye can lead to:

      A.   amblyopia
      B.   anisometropia
      C.   Anisocoria
      D.   anaphylaxis

5. Amblyopia that results when each eye has a different uncorrected
refractive error is called _______ amblyopia.

      A.   strabismic
      B.   anisometropic
      C.   refractive
      D.   meridional

6. Which is a common treatment for amblyopia?

      A.   full refractive correction
      B.   patching the better eye
      C.   patching the amblyopic eye
      D.   A and B

7. A positive (normal) response to the Four Diopters Base-out Prism
Test is:

      A.   a divergence movement of the eye
      B.   a convergence movement of the eye
      C.   no movement of the eye
      D.   excessive blinking

8. When performing the Worth 4 Dot test, the right eye has the red lens
in front of it. If the patient is viewing the test with both eyes and she sees
two red lights to the left of three green lights, this indicates:

      A.   an exo deviation (crossed diplopia)
      B.   an eso deviation (uncrossed diplopia)
      C.   a right hyper deviation
      D.   a left hyper deviation

                                                              Good Luck
