Children with amblyopia and strabismus may experience reading difficulties impacting school support. Standardized tests reveal potential reading deficits even after treatment, suggesting further assessment for reading supports.
Area of Science:
- Ophthalmology
- Developmental Psychology
- Educational Psychology
Background:
- Previous research indicates reading impairments in children with amblyopia.
- Standardized testing and practical implications for school support have been under-assessed.
- Atypical reading conditions and treatment effects on reading remain unclear.
Purpose of the Study:
- To compare binocular reading performance in treated amblyopia patients to normative samples and control groups using standardized tests.
- To assess the impact of strabismus and amblyopia on reading ability.
- To determine if reading deficits warrant school-based reading support.
Main Methods:
- Children with treated strabismic/anisometropic amblyopia (N=14) and strabismus without amblyopia (N=12) were compared to healthy controls (N=39).
- Standardized assessments included visual acuity, stereoacuity, interocular suppression, intellectual functioning, oral single-word reading (TOWRE-2), and oral paragraph reading (GORT-5).
Main Results:
- The control group demonstrated significantly higher single-word reading accuracy than both patient groups.
- Despite average mean performance across all groups, six children (four amblyopia, two strabismus) scored below average in single-word reading.
- Four of these children also exhibited below-average paragraph reading, independent of visual acuity.
Conclusions:
- Both strabismus and amblyopia may negatively affect reading ability, even post-treatment.
- Reading performance deficits, though not always correlated with visual acuity, may warrant consideration for school reading support.
- Standardized assessments are crucial for identifying children who could benefit from reading interventions.
