DISEASES OF THE VISUAL SYSTEM
Learning outcomes of the course unit
To promote basic knowledge of vision mechanism, from the first step (photoreceptors) to final step (occipital visual cortex). To learn the basic principles of the physiopatology of visual function.

During the lectures will be presented and discussed the topics listed in
the program trying to involve the student so that he/she can be an active
part of the lesson.
Assessment methods and criteria
The assessment of the achievement of the objectives set by the course includes a written examination.
Through questions regarding the course content, it will be determined if the student has achieved the goal of knowledge and understanding of the content. Through questions concerning the principles of operation and interpretation of the techniques discussed in the course, will be determined whether the student has achieved the goal of applying the acquired knowledge.
To pass the exam, the student must correctly answer at least 60% of the questions. The final grade is out of thirty, in proportion to the number of correct answers. And 'provided that the student can improve your score in the written application through an oral, that may change the rating of no more than 3 points.
