Evaluation of the accuracy of subjective refraction according the negative relative accommodation and accommodation response
Journal Title: Eye Science (Yanke Xuebao) - Year 2020, Vol 35, Issue 6
Abstract
[Objective:] To observe the consistency of the objective results of primary small-pupil optometry and ciliary muscle paralysis in children with suspected myopia aged 8–15 years with different adjustment states, and to analyze its reference significance for prescription of glasses. [Methods:] In this prospective study, a total of total of 105 adolescents with suspected myopia were recruited from Foshan Aier Eye Hospital from January to June 2019. The differences in non-cycloplegic subjective refraction, cycloplegic refraction in children with incipient myopia were compared. The right eye data were taken for statistical analysis. According to the negative relative accommodation and whether the accommodation response was within the normal value range, all subjects were divided into the normal accommodation group and the abnormal accommodation group. The analysis of variance was used for statistical analysis. Bland-Altman was used for consistency analysis. [Results:] A total of 83 patients were adjusted in the normal group. The non-cycloplegic refraction equivalent spherical was (−2.02±1.03) D, and equivalent spherical diopter of the cycloplegic refraction was (−1.91±1.01) D, 1.20% (1/83) was beyond the 95% consistency limit. The refraction results of the two methods have good consistency. The equivalent diopter of the non-cycloplegic refraction in the abnormal group was adjusted to (−2.33±1.34) D. The objective refraction equivalent spherical diopter of the cycloplegic was (−1.96±1.15) D. The 50% (11/22) point have beyond the 95% consistency limit. Therefore, for the adjustment of the abnormal group, the two methods were not consistent. [Conclusion:] Glass prescription can be delivered for adolescents with suspected myopia at the age of 8–15 years old, children with negative relative accommodation and adjustment response in the normal range of myopia according to accurate subjective refraction. Otherwise, cycloplegic refraction can be given according to the actual situation.
