Across
  1. 1. When the eye is ____ in the right and up gaze, it is the inferior oblique muscle working.
  2. 4. A single image formed with images from both eyes.
  3. 5. The visual axis of the eyes is misaligned, leaving the eyes appearing as though they are looking in different directions.
  4. 9. Smooth ____, slow movements of the eyes to follow an object. Controlled by the parietal-occipital region of the brain, plus a few others.
  5. 11. The lateral rectus' function is ____.
  6. 12. ____ muscles refers to one muscle from each eye acting together to cause movement.
  7. 14. When the eye is ____ in the right and up gaze, it is the superior rectus muscle working.
  8. 16. Keeping an image on the fovea.
  9. 20. A modified Krimsky test places the prism in front of the ____ eye.
  10. 21. Prefix for outward turning of the eye.
  11. 25. The superior ____ muscle has a primary function of elevation, and a secondary function of intorsion.
  12. 27. Binocular movements of the eyes in the same gaze.
  13. 29. Both eyes look away from each other to maintain fusion.
  14. 31. Fast movements of the eye that keep an image on the fovea. Controlled by the frontal lobe.
  15. 34. The medial rectus' function is ____.
  16. 35. An eye affected by Duane's syndrome ____ on adduction.
  17. 37. Prefix for upward turning of the eye.
  18. 38. This law dictates the antagonist muscle should receive less nerve supply to relax on the opposite side of the movement.
  19. 39. Both eyes looking left.
  20. 40. The four ____ test tests for diplopia, suppression, and strabismus. It is a dissociation test.
  21. 42. This law dictates that both yoke muscles should get equal innervation from the nerves to work together.
  22. 43. This test for strabismus is quantitative. It measures how much prism it takes to center the deviation on the eye.
  23. 44. Both eyes looking down.
Down
  1. 2. Two images are perceived, one from each eye. There is a lack of fusion. (Hint: double vision)
  2. 3. This is the primary function of the superior oblique. The secondary function is depression.
  3. 6. An eye turn that is constantly present. It is manifest, and is seen right away.
  4. 7. An eye turn that is occasionally present. It is hidden, and is seen only when fusion is broken.
  5. 8. Monocular movements of the eye.
  6. 10. Both eyes look towards each other to maintain fusion.
  7. 13. The benefits of ____ vision are: stereo vision (depth perception), increased field of vision, and compensation for the blind spot.
  8. 15. The ____ of strabismus are: accommodative esotropia, congenital strabismus, cranial nerve palsies, decompensated strabismus, trauma, Duane syndrome, and Brown syndrome.
  9. 17. The ____ rectus muscle has a primary function of depression, and a secondary function of extorsion.
  10. 18. ____ syndrome is an incorrect innervation of the extra-ocular muscles by the cranial nerves, and is mostly congenital. A muscle contracts when it should relax, and vice versa.
  11. 19. This test for strabismus is qualitative. A light is shone in the eyes and the examiner observes where the light reflects off the pupil to determine the presence of strabismus.
  12. 22. ____ syndrome occurs when the tendon of the superior oblique is too tight or too short. It is usually congenital, but can also occur due to surgery or trauma. Looking up causes diplopia, and it is usually unilateral.
  13. 23. Both eyes looking up.
  14. 24. The amount of strabismus is measured in prism ____.
  15. 26. This test is the more sensitive of the two for stereopsis, and is easier for adults than for kids.
  16. 28. Prefix for downward turning of the eye.
  17. 30. Prefix for inward turning of the eye.
  18. 32. Reduced best corrected visual acuity if the visual system in the brain does not receive clear images during development. (Hint: lazy eye)
  19. 33. This is the primary function of the inferior oblique muscle. The secondary function is elevation.
  20. 36. When the brain ignores one of the images during diplopia.
  21. 41. Both eyes looking right.
