Summary of the Wyoming State Guidelines
1. Required Screenings
In the state of Wyoming, comprehensive vision screenings are conducted at multiple grade levels using validated tools and techniques.
-
Kindergarten (or first entry into district):
- Monocular Distance Visual Acuity (HOTV optotype wall chart at 10 feet)
- Binocular Near Visual Acuity (HOTV near chart with cord)
- Stereoacuity (PASS Test 2)
- Color Vision (Color Vision Testing Made Easy)
-
Grades 1, 2, 3, 5, 7, and 10:
- Monocular Distance Visual Acuity (SLOAN optotype wall chart at 10 feet)
- Binocular Near Visual Acuity (SLOAN near chart with cord)
- Stereoacuity (PASS Test 2)
Instrument-Based Screening: May be used for children 6 years and older who cannot complete optotype-based screening.
2. Screening Referral Criteria (Criteria for Passing Vision Test)
Monocular Distance Visual Acuity
- Kindergarten: Refer if unable to identify 3 of 5 optotypes on 20/40 line or if there’s a 2-line difference between eyes
- Grades 1–12: Refer if unable to identify 3 of 5 optotypes on 20/32 line or if there’s a 2-line difference between eyes
Binocular Near Visual Acuity
- Kindergarten: Refer if unable to identify 3 of 5 optotypes on 20/40 line
- Grades 1–12: Refer if unable to identify 3 of 5 optotypes on 20/32 line
Stereoacuity (PASS Test 2)
- Refer if unable to pass all test cards (B and C)
Color Vision
- Refer for any incorrect responses based on manufacturer instructions
3. Children Who Should Bypass Screening
- Recognized eye abnormalities (e.g., strabismus, ptosis)
- Diagnosed neurodevelopmental disorders (e.g., cerebral palsy, autism)
- Systemic diseases affecting vision (e.g., diabetes, juvenile rheumatoid arthritis)
- Family history of strabismus, amblyopia, or high refractive error in a first-degree relative
- Premature birth or low birthweight without a prior normal eye exam
- Parental concerns about vision or developmental milestones
- Students with an IEP or 504 Plan: Screening may still be attempted, but referral for comprehensive exam is encouraged
4. Required Tools OR Important Changes to Tools Used/Discontinued
Required Tools
- Distance Charts: HOTV (Kindergarten), SLOAN (Grades 1–12)
- Near Charts: HOTV or SLOAN charts with cord
- Stereoacuity Test: PASS Test 2
- Color Vision: Color Vision Testing Made Easy or School Health HRR Color Screening Book
- Acceptable Occluders: Handheld paddles, adhesive patches, or occluder glasses
- Unacceptable Occluders: Paper, tissues, hands, or cups
Screening Notes
- Instrument-Based Screening: Not validated for general use with children 6+ unless they are unable to complete optotype testing
- Proper occlusion methods must be used to ensure test validity
