integrated course unit
7 credits
hub:
course unit
in ITALIAN

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.

Prerequisites

None

Course unit content

Teaching methods

The topics contained in the Programmes of the Modules will be illustrated
and discussed during classroom lectures in presence / remotely (in synchronous / asynchronous mode).
In specific cases, lectures will be integrated by active teaching through
individual and group exercises and practical activities.

Assessment methods and criteria

The achievement of the objectives will be
established during oral examination
in presence / remotely using Microsoft Teams. Through questions on the topics covered in the course will assess the
knowledge and understanding of the content by the student.
