Fig 10. Randot Preschool stereo thresholds by age-group, color-coded to indicate whether any binocular vision problems were identified.

Fig 10

Parent: parental questionnaire indicated strabismus or amblyopia; CTFAIL: cover test found heterotropia; ModVI: acuity in worse eye > 0.48 logMAR; IADonly: interocular acuity difference >0.3 logMAR (but no other abnormality). Note that each type of binocular vision problem includes the ones on the right; e.g. those colored red for ‘CTFAIL’ may also have had acuity >0.48 logMAR in one eye, but those colored brown for ‘ModVI’ must have passed the cover test.
