In accommodative esotropia managed with spectacle correction, a child wearing full cycloplegic refraction still shows residual esodeviation at near > distance. This suggests:
- A High AC/A ratio component — bifocals (executive or progressive addition lens) should be prescribed to reduce the near esodeviation ✓
- B Non-accommodative component requiring surgical correction based on the residual distance deviation
- C Consecutive esotropia from over-correction with glasses; lenses should be reduced
- D Microtropia with anomalous retinal correspondence requiring orthoptic exercises
Explanation
When a child with accommodative esotropia wears full hypermetropic correction and shows significantly larger esotropia at near compared to distance (near-distance disparity > 10 PD), this indicates a high accommodative convergence/accommodation (AC/A) ratio. The excess near convergence occurs because the child accommodates more than expected at near (high AC/A), generating excess convergence beyond what glasses correct for distance. Management requires bifocal spectacles — executive bifocals with the segment at the lower pupil margin or progressive addition lenses — with a near add of typically +2.00 to +3.00 D. This reduces the accommodation at near, thereby reducing convergence. Surgical correction is considered if bifocals fail to control the near deviation.
