Course Objectives:
To understand the basic ocular stretcher and its anatomical importance
Course Outcomes:
At the end of the course, the student should be able to:
Comprehend the normal disposition, inter-relationships, gross, functional and applied anatomy of various structures in the eye and adnexa.
Identify the microscopic structures of various tissues in the eye and correlate the structure with the functions.
