  5. VISION SCREENING CERTIFICATION

  6. One in 20 preschoolers has a vision problem. One in 5-10 school-aged children has a vision problem. Impaired vision can seriously impede learning. Early identification and treatment can prevent or at least alleviate many vision problems. Importance of Vision Screening

  7. Purpose of Vision Screening To screen a large number of children in a short amount of time. To separate those children likely to have vision problems from those not likely to. To refer those children who do not pass the screening or who are suspect for vision problems.

  8. Landmarks of Visual Development 4-12 wks Binocular fixation 12-20 wks 20/200 44 wks-12 mo 20/50 - 20/100 Full binocular vision Amblyopia may develop 6 -18 mo Convergence developed 18 mo-2 yrs Accommodation developed 20/40 2-3 yrs 20/30 5 yrs Min. potential for amblyopia 6 yrs Approaches 20/20

  9. Parts of the Eye

  10. Common Ocular Abnormalities

  11. Black Eye

  12. Conjunctivitis

  13. Blepharitis

  14. Chalazion

  15. Stye

  16. Entropion Of upper eyelid due to scarring Of lower eyelid

  17. Dacryocystitis

  18. Ptosis

  19. Coloboma

  20. Coloboma

  21. Cataract

  22. Strabismus Types Tropia Eyes which are always improperly aligned Phoria Eyes which have a tendency to misalign when fusion is interrupted

  23. Esotropia

  24. Bilateral Esotropia

  25. Exotropia

  26. Hypertropia

  27. Pseudostrabismus(also Pseudotropia or pseudoesotropia)

  28. Refractive Errors Myopia (Nearsightedness) Hyperopia (Farsightedness) Astigmatism

  29. Astigmatism

  30. Amblyopia: Definition Vision that cannot be corrected to better than 20/40. Unilateral or bilateral Brain suppresses poor image Normal appearance Reversible if detected and treated early

  31. Amblyopia Predisposing Factors Poor clarity Cataract Poor focus Nearsightedness Farsightedness Poor aim Strabismus Treatment Clearing the media Cataract removal Focusing the image Corrective lenses Correcting aim Occlusion therapy Drops

  32. Amblyopia Therapy

  33. Usher’s Syndrome Hearing Loss and Retinitis Pigmentosa Screen children with hearing loss

  34. VisionScreening

  35. Screening Procedure

  36. Observation Appearance Behavior Complaints

  37. Appearance Whites Iris Pupil Lids Lashes Immediate referral if abnormal

  38. Behavior Head tilt or turn Blinking or rubbing Avoiding close work Squinting/frowning Closing or covering eye Reading problems Frustration/poor attention

  39. Complaints Headaches Nausea Dizziness Burning or itching Blurring

  40. Visual Acuity-Far Screen one eye at a time. If a child wears glasses, perform the screening with the child wearing the glasses. Screen at 20 feet – Snellen Chart Literate children Screen at 10 feet – Age Appropriate Chart Allen Chart/Tumbling E’s Pre-literate children/non-English speaking Any eye with vision poorer than 20/40 is a screen failure.

  41. Plus 2 (+2.00) Visual Acuity Test for farsightedness. Perform exactly as the distance visual acuity except; Hold a +2.00 lens in front of the tested eye (fellow eye covered). Any eye that improves 2 lines of vision with the +2.00 lens is a screen failure.

  42. Instrument Screenings Titmus Optec Keystone

  43. Lateral & Vertical Muscle Balance-Far (Titmus & Optec) Right eye on; left eye off. Give instructions: “Here is a box. I will throw a red ball. Tell me where the ball lands.” Turn left eye on. Need immediate answer. If not, repeat test. To pass the child should report the ball landing ‘in the box’ or ‘on the line’.
