PATHOPHYSIOLOGY OF VISUAL FUNCTION AND BINOCULAR VISION
Learning outcomes of the course unit
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.
