Course unit structured in the following modules:

Learning objectives

To understand the principle of diseases affecting different levels of the visual system: different effects imply different diagnostic strateg.
To gain fundamental insight about binocular vision, stereopsis, and their impairment.
Pathophysiology of binocular vision.
To develop an elementary knowledge on the principles underlying the function of ophthalmic instruments.
