1. 1. SCOPE:
• Study about Vision, Visual Acuity, Visual Perception and the Visual System
• Learn about the Anomalies of the Visual System
• Learn about the Diagnostic Procedures available for detecting the anomalies
• Gain knowledge about the Treatment Modalities for correcting these anomalies
OBJECTIVE:
•
Prepare the students to Evaluate, Diagnose and Treat the various anomalies of the visual
system that they will encounter in clinical practice
