Learning outcomes In this curricular unit it is intended that the student achieve knowledge upon microscopic, macroscopic and functional mechanisms underlying vision of objects and associated pathology At the end of this curricular unit the student should be able to understand eye´s anatomy, visual pathways´ anatomy and their function, as well as the physiology of movement vision, colour vision and light vision. The student will also be able to understand the pathology associated with the loss of vision, the changes in ocular movements and the pathology associated with movement perception, shape and colour both at anatomical and functional levels. The student will also be able to read, understand and to discuss a scientific article related with this subject.
Syllabus 1. Anatomy macroscopic of the eye.
2. The retina and the optic nerve. Physiology of the nervous impulse. Image formation and transformation in nervous stimulus.
3. Anatomical localization of the visual pathways and transmission of information on optic nerve.
4. Pathology of visual pathways - hemianopsy and quadrantanopsy.
5. Anatomy of the visual cortex.
6. Cranial nerves (III, IV and VI). Origin, physiology and pathological changes.
7. Perception of movement, of deepness and shape of an object.
8. The Magno and parvocelular pathways. The visual cortex and movement perception.
9. Colour vison and pathology.
10. Visual perception and illusions.
11. Visual agnosia to shape and pattern and movement.
12. Neurologic and non neurologic causes of partial and total blindness.
13. Headache attributed to ocular disorder.

Planned learning activities and teaching methods The UC comprises theoretical-practical and laboratory classes. The theoretical-practical classes are organized by combining two teaching methods: - Exposure classes (supported by slides) and presentation and discussion of scientific papers by the students. Thereby, the exposition to theoretical-practical content allows the student to become familiar with fundamental concepts necessary for understanding the neurosciences of vision as a crucial area in primary care visual health process. Each topic is accompanied by reading, presentation and discussion of clinical cases, which enables students not only check the consolidation of acquired concepts, as to develop skills of critical analysis, discussion, synthesis and communication.
Metodologias de Ensino e Critérios de Avaliação A classificação final do período de ensino-aprendizagem (CEA) é calculada de acordo com a seguinte expressão:

CEA = 2/3 T + 1/3 CC

T: classificação obtida no teste teórico
CC: classificação obtida na apresentação e discussão de um artigo científico.

Critérios de aprovação em período de ensino e aprendizagem: CEA maior ou igual a 9.5 valores e T maior ou igual a 8 valores. Como critério adicional para concessão de frequência consiste na obrigatoriedade de realizar todos os momentos de avaliação.

A classificação final no período de exames (CE) será determinada pela classificação obtida na prova teórica realizada durante este período de avaliação.

A classificação final (CF) na unidade curricular será a melhor classificação obtida entre CEA e CE.

Language Portuguese. Tutorial support is available in English.
