General competences
Know the sensory physiology in general, and the visual system in particular
The students will increase their capacity of analysis and synthesis to solve specific physiological problems.
The student must understand and know the functioning of the different sensory systems (excluding the auditory system that will be studied as an independent subject) and summarize the mechanisms common to all of them and specific to each one in particular; including the mechanisms of the different types of peripheral receptors, the initial phenomena of peripheral transduction and integration (in the case of vision), conduction, and the processing and integration of the information at the central level.
The student will understand the functioning of the different components of the eyeball, the eyelids, the ocular blood circulation, the lacrimal secretion etc.
That students have demonstrated to possess and understand knowledge in an area of study that starts from the base of general secondary education, and is usually found at a level that, although supported by advanced textbooks, also includes some aspects that imply knowledge coming from the vanguard of their field of study.
Basic competences
BC1. That students know how to apply their knowledge to their work or vocation in a professional manner and possess the skills that are usually demonstrated through the elaboration and defence of arguments and the resolution of problems within their area of study.
BC2. That students have the ability to gather and interpret relevant data (usually within their area of study) to make judgments that include a reflection on relevant issues of social, scientific or ethical nature.
BC3. That students can transmit information, ideas, problems and solutions to a specialized and non-specialized public.
BC4. That the students have developed those learning skills necessary to undertake further studies with a high degree of autonomy.
Transversal competences
TC1-Acquire analysis and synthesis skills
TC2-Acquire organizational and planning skills
TC3-Acquire knowledge of a foreign language
TC4-Acquire computer skills related to the field of study
TC5- That they acquire information management skills.
TC6-That they acquire the capacity for problem-solving.
TC7-That they know how to work as a team.
TC8-That they acquire skills in interpersonal relationships.
TC9-That the student acquires skills for issuing critical reasoning.
TC10-That the student maintains an ethical commitment.
TC11-That the student is able to carry out autonomous learning.
TC12-That they are able to adapt to new situations.
Specific competences
SC1- That the student be able to reflect critically on clinical, scientific, ethical and social issues involved in the professional practice of Optometry, understanding the scientific foundations of Optics-Optometry and learning to critically evaluate terminology, clinical trials and research methodology related to Optics-Optometry.
SC2- That the student be able to issue opinions, reports and expert opinions when necessary.
SC3 - That the student can assess and incorporate the technological advances necessary for the proper development of their professional activity.
SC4 - That the student can expand and update their capacities for professional practice through continuous training.
SC5 - That the student knows how to situate the new information and the interpretation of it in its context.
Scenario 1
Face-to-face lessons: physical class attendance, 3 times per week, during the second semester. In the theoretical lessons, student participation will be encouraged, as well as their critical spirit.
Practical / Seminars / Interactive Classes: These classes will be compulsory.
Practical Class: Determination of the visual field in a Goldmann campimeter. Effect of the characteristics of the stimulus and adaptation to light.
Seminars: Topics will be presented to deepen the concepts previously exposed in the theoretical lessons. Students are expected to actively participate.
Scenario 2
Face-to-face lessons: physical class attendance, 3 times per week, during the second semester that will alternate with online teaching to reduce the physical attendance to 50%. In the theoretical lessons, student participation will be encouraged, as well as their critical spirit.
Practical / Seminars / Interactive Classes: These classes will be compulsory. The physical attendance to practical classes and seminars will be replaced by online content and tasks through the virtual classroom of the USC.
Scenario 3
Face-to-face lessons: Online resources will be used, mainly through the USC virtual classroom. Teaching material will be uploaded to the platform, and tests or forums will be created to facilitate the study and understand the content of the subject.
Practical / Seminars / Interactive Classes: These classes will be compulsory. The physical attendance to practical classes and seminars will be replaced by online content and tasks through the virtual classroom of the USC.
These assessment criteria will be valid for both the ordinary semester and extraordinary recovery opportunities.
The Ocular Physiology exam will be carried out on a date and time previously established by the Faculty of Optics and Optometry.
The exam will be done by physical attendance (Scenario 1) or using the online platform that the USC approves if due to health conditions it is not possible to conduct it in person (Scenario 2 and 3).
The final exam will consist of a multiple-choice test. The number of questions from each professor will be equal or proportional to the number of hours of theoretical lessons. The course is indivisible and is passed or failed in its entirety. The exam will constitute 80% of the final grade. It will be necessary to obtain 60% of total successes in the exam and a minimum of 40% of successes in the questions posed by each professor in order to sum the scores obtained in the continuous evaluation.
The attendance to the classroom or online classes and the realization of academic activities proposed through the virtual classroom will sum 20% of the final grade, provided that the minimum required in the final exam is reached.
Newly enrolled students who do not carry out the activity related to the practical lesson and the proposed seminars will not be evaluated.
Student personal work (study, recommended readings, attendance at recommended talks).
• Individual study time or in the group: 60 hours
• Recommended reading, activities into the library or similar: 10 hours
• Oral talks or similar: 10 hours
• Assistance to lectures, expositions or recommended activities: 5 hours
• Total hours student´s individual work: 90 hours
• Assistance to lectures
• To check the recommended bibliography in the library
• Use the material from the virtual classroom
• Make use of the tutorials
• Do the activities proposed through the virtual classroom.
Tutorized activities.
Students can request tutoring whenever they require it, by previously contacting the professors via email. Students are recommended to use tutorized activities.
