Children with amblyopia who were not identified at preschool vision screening by the Sheridan–Gardiner single optotype test of visual acuity
| Child | Reason for failing preschool vision screening | HES findings | Snellen line acuity |
|---|---|---|---|
| 1 | Decompensating esophoria + negative stereopsis | Anisometropic amblyopia | 6/9 6/5 |
| 2 | Decompensating exophoria + poor motor fusion | Unilateral posterior polar cataract with amblyopia | 6/12 6/6 |

↵Unaided Snellen line acuity recorded at HES before occlusion therapy was commenced. In both cases, the unaided visual acuity at preschool vision screening was 6/6 in each eye with a Sheridan–Gardiner single optotype test.
