Course Name : Binocular Vision I

Code(Credit) :CUTM1796 (3-2-0)

Course Objectives

  • This course provides theoretical aspects of Binocular Vision and its clinical application. It deals with fundamentals of normal binocular vision and space perception, gross anatomy and physiology of extra ocular muscles, binocular movement coordination and binocular optical defects, amblyopia & nystagmus

Course Outcomes

At the end of the course students will be able to,
CO1:Understand the concepts of grades of Binocular vision and Fundamental theories of binocular vision.

CO2: Apply knowledge in binocular muscle coordination and integration of motor and sensory system into binocular vision.

CO3: Identify non strabismic anomalies related to accommodation

CO4: Evaluate different types of strabismic anomalies - horizontal, vertical, torsional, paralytical& mechanical restrictive.

CO5: Create differential binocular visual condition practice in daily basis.
