Abstract: Objective To investigate the association between accommodative response and refractive degree in incipient myopia children. Design Retrospective case series. Participants The study included 96 with age 8 to 10 years old, the vision blurring within 6 months, and the cycloplegic myopic degree lower than -1.00 D. Method All participants underwent ophthalmology examination, subjective refraction, accommodative response, accommodative facility, negative relative accommodation, and positive relative accommodation examination. The degree of less myopic eye was selected for statistical analysis. Main Outcome Measures Myopic diopter, accommodative response, accommodative facility, relative accommodation. Results The mean myopic refraction of participants was -0.66±0.25 D. The value of accommodative response was 0.25±0.36 D. The value of accommodative facility was 6.31±2.54 cpm. The value of negative relative accommodation was 2.20±0.40 D and the value of positive relative accommodation was -1.96±1.32 D. The accommodative response and myopic diopter were negatively correlated. The accommodative facility and accommodative response were positively correlated. The accommodative response and the negative relative accommodation were negatively correlated. The accommodative response and the positive relative accommodation were positively correlated.  Conclusion The accommodative lag has been existed in the incipient myopia children. The accommodative lag and positive relative accommodation reduced might be involved in the pathogenesis of myopia. (Ophthalmol CHN, 2014, 23: 319-322)
