Abstract:
AlM:To discuss the feasibility of microcoria optometry in screening for children ametropia. METHODS: Totally 217 school - age children were selected, included 94 first-grade students ( 6 ~ 8 years old) and 123 fourth-grade students ( 9 ~12 years old ) . Refractive diopter was measured with automatic refractor RM-8000 to evaluate the accuracy of micocoria optometry in screening ametropia.RESULTS: After cycloplegia, both the mean sphere diopter and cylinder diopter in grade one students changed significantly (P<0. 05), the mean sphere diopter in grade four students changed significantly (P<0. 05), while the mean cylinder diopter had no statistical difference ( P>0. 05 ) in grade four students. Different refractive type: before and after mydriasis spherical myopia, spherical equivalent difference was 0. 263 ± 0. 618 and 0.216±0.653D, with statistical significance (P<0.01);ln hyperopia group, spherical myopia, spherical equivalent difference was 0. 947±0. 946 and 1. 039±0. 984D, with statistical significance ( P = 0. 000 ). The lenticular difference between the two groups were not statistically different ( P > 0. 05 ). Choosing small pupil computer optometry for ≤- 1. 00D, ≥- 0. 50D child myopia or hyperopia could get more accurate value of diagnostic cutoffs, Youden index was 0. 672 and 0. 580. CONCLUSlON: Microcoria optometry can be as a effective method of screening of children with ametropia, but if for optometry, school-age children must accept mydriasis.
