Objective

Knowledge base
Students are able to
• explain the principles of binocular vision and anatomical foundations for it
• describe significance of binocularity to vision and its development in childhood.
• distinguish binocular vision disorders and describe the factors causing them, symptoms and treatments
• distinguish accommodation disorders and describe the factors causing them, symptoms and treatments
• describe the principals of the tests of the binocular vision and accommodation
• assess normality of the test values of binocular vision and accommodation
• calculate the corrective prism and spherical dioptric correction to control accommodative convergence

Clinical/practical base
Students are able to
• assess near vision and function of the accommodation
• assess extra ocular muscle balance, measure phorias and vergences
• assess binocular vision, fixation disparity, stereo acuity
• record the test results with understandable and agreedable notation (KANTA, ICD10)
