  1. OCEAN MEDICAL CENTER STROKE SERIES

  2. AWARENESS OF VISUAL SEQUELLA OF STROKES

NORMAN P EINHORN OD MS FAAO Diplomate American Board of OptometryNational & International Lecturer NORPast AOA Membership Chair SVSPast NJSOP Board MemberPast Chair NJSOP Rehabilitation SectionSenior member Vision Panel NJ MVCExecutive Committee Belmar Business PartnershipStaff Consulting Privileges 5 Acute Rehab Hosptals

  4. Visual Deficits Post CVAto watch for Field Loss or Visual Inattention Diplopia or Binocular Deficits Spatial Deficits Dry eye caused by poor lid closure, partial CN7 or CN 5 Ophthalmic Branch loss Inability to read or scan

  5. RETINA STRUCTURE FUNCTION

  6. RETINAL STRUCTURE

  7. GANGLION CELS

  8. THREE PARALLEL PATHWAYS

  9. BASE OF BRAIN

  10. AFFERENT PAHTWAY RETINO GENICULATE CALCARINE PATHWAY

  11. RETINO GENICULO CALCARINE PATHWAY

  12. OPTIC TRACTS AND LATERAL GENICULATE

  13. GANGLION CELL INPUT TO LGN LAYERS

  14. THALMUS &LATERAL GENICULATE • Specific relay nuclei • VA ventral anterior (motor) • VL ventral lateral (motor)(somatosensory) • VPM ventral posteromedial (trigeminal) • MG medial geniculate (body) nucleus (auditory) • LG lateral geniculate (body) nucleus (vision) • Association nuclei • DM dorsomedial nucleus (prefrontal cortex) • AN anterior nucleus (limbic lobe) • P pulvinar (visual cortex) • LP lateral posterior (parietal lobe) • Nonspecific nuclei • IL intralaminar

  15. OPTIC RADIATIONS

  16. PRIMARY CORTEX – VISUAL ORGANIZATION

  17. THREE PARALLEL PATHWAYS

  18. PRIMARY CORTEX – VISUAL ORGANIZATION

  19. Territories Supplied by the Cerebral Arteries

  20. SHORT ASSOCIATION FIBERS

  21. LONG ASSOCIATION FIBERS

  22. AFFERENT PATHWAY EXTRA GENICULATE PATHWAY Magno cellular

  23. EXTRA GENICULATE PAHTWAY

  24. EXTRA GENICULATE PATH Although this figure again illustrates the optic radiation and the lateral geniculate nucleus [a nucleus with six layers], the focus is now on the synaptic terminations of other visual fibers. Some of the visual information is relayed to the superior colliculus for visual reflex responses. Other fibers relay in the pre-tectal region which is the locus for the pupillary light reflex. The oculomotor nucleus (including the parasympathetic component) is not shown here.

  25. RETINO SUPERIOR COLLICULUS

  26. SUPERIOR COLLICULUS FIBERS AND MOTOR FIBERS

  27. AFFERENT PATHWAY RETINO HYPOTHALAMIC PATHWAY

  28. AFFERENT PATHWAY PRE TECTAL PATHWAY

  29. Visual Field Loss By Deficit Areas

  30. Review

  31. EFFERENT EYE MOVEMENT

  32. CLASSES OF HUMAN EYE MOVEMENT VESTIBULAR-HOLDS IMAGES OF THE SEEN WORLD STEADY ON THE RETINADURING BRIEF HEAD ROTATIONS VISUAL FIXATION- HOLDS THE IMAGE OF A STATIONARY OBJECT ON THE FOVEA OPTOKINETIC- HOLDS AN IMAGE OF THE SEEN WORLDSTEADY ON THE RETINADURING SUSTAINED HEAD ROTATION

  33. CLASSES OF HUMAN EYE MOVEMENT SMOOTH PURSUIT- HOLDS AN IMAGE OF A SMALL MOVING TARGET ON THE FOVEA; OR HOLDS THE IMAGE OF A NEAR TARGET ON THE RETINA DURINGLINEAR SELF MOTION NYSTAGMUS QUICK PHASE- RESET THE EYES DURING PROLOGED ROTATION AND DIRECT GAZE TOWARD THE ONCOMING VISUAL SCENE

  34. CLASSES OF HUMAN EYE MOVEMENT SACCADES- BRINGS IMAGES OF OBJECTS OF INTEREST ONTO THE FOVEA VERGENCE- MOVES THE EYES IN OPPOSITE DIRECTIONSSO THAT IMAGES OF A SINGLE OBJECTARE PLACED OR HELD SIMULTANIOUSLY ON BOTH FOVEAS.

  35. SMOOTH PURSUITS
