Course objectives
After this course of lectures, student will be able to define a term single binocular vision (SBV). Student will know the components of SBV vision and he or she will also know the factors that affect the correct development of SBV. Student will be introduced to the defects of SBV– such as suppression, amblyopia (lazy eye) and anomalous retinal correspondence. Student will understand the term strabismus and he or she will know its aetiology and basic types. Student will get basic knowledge about diagnostic methods and possibilities of conservative treatment of strabismus – pleoptics and ortoptics – and also about its surgical treatment. SBV vision is ability to see with both eyes single image. It isn´t inborn, it develops until one year and is refined until six years. It divides artificially into 3 grades. SBV is important for the selection of profession and also for social relations and life. Significant defects of SBV are strabismus and amblyopia. Strabismus is treated with glasses, occlusion, pleoptics (conservative treatment of amblyopia), surgery and orthoptics (conservative treatment of binocularity). Paralytic strabismus arises from palsy of oculomotor nerves, muscles or defect of central nervous system. Palsy also manifests as an eye´s deviation and consequent SBV defects.
Syllabus
  • Complex multilevel nature of fusion (introduction, division). Sensory arm of fusion (subjective visual direction, retinal correspondence, …… , physiological diplopia, functional neuroanatomy of visual pathway and V1, convergence of the corresponding signals, first binocular neuron, …). Motor compnent of the fusion (duction, version, vergence, Shering´s , Hering´s , Listing´s law, neural control of saccades and vergencies, fixation disparity, …). Analytical and psychogenic component of fusion (harmony conflict and disparity of corresponding signals, detection and processing of disparity signal and blur signal, Panum´s fusional area, monocular and binocular stereopsis, vergence - accommodation synkinesis, relative accommodation, relative vergence, monocular dominant column of V1, detection of edges and contrast, receptive fields, visual illusions, …). Binocular vision development (prestereopsis, development of the fusion’s components). Pathophysiology of suppression, binocular rivality and dichoptic masking, anomalous retinal correspondence, ….
