Refractive Accommodative Esotropia
Inward eye turn that occurs when uncorrected hyperopia triggers excessive accommodation and convergence.
Full Definition
Refractive accommodative esotropia develops when significant hyperopia requires excessive accommodative effort to maintain clear vision, resulting in associated convergence that exceeds fusional divergence capabilities. This condition typically manifests between ages 2-4 years when accommodative demands increase with near visual tasks. The esotropia is present for both distance and near fixation and can be completely corrected with appropriate hyperopic spectacle correction. Diagnosis requires demonstrating that the eye misalignment resolves or significantly reduces with cycloplegic refraction-based spectacles. Early optical correction is crucial to prevent amblyopia and loss of binocular function, and most patients require lifetime spectacle wear.
Usage
Usage note: Always specify the degree of hyperopic correction required and document complete vs. partial accommodation response.
