TABLE 1.
Refractive Thresholds Used for the Three Gold Standards Used for Evaluationa
| Gold Standard | Hyperopia (D) | Myopia (D) | Astigmatism (D) | Anisometropia (D) |
|---|---|---|---|---|
| 1: AAPOS > 48 months | > +3.50 | > −1.50 | > +1.50 | > +1.50 |
| 2: Spot Vision Screener refractive criteria age (range: 72 to 240 months) | ≥ +2.50 | ≥ −1.00 | ≥ +1.50 | ≥ +1.00 |
| 3: Stricter criteria | ≥ +2.00 | ≥ −0.75 | ≥ +1.00 | ≥ +1.00 |
AAPOS = American Association for Pediatric Ophthalmology and Strabismus; D = diopters
a
Non-refractive errors of media opacity and manifest strabismus greater than 8 prism diopters were included for all three analyses.
The Spot Vision Screener is manufactured by Welch Allyn, Skaneateles Falls, NY.
