Abstract

BACKGROUND

Many theories of myopia etiology suggest differences in accommodation and convergence in children who become myopic. Several studies have found differences in accommodation and convergence in myopes and emmetropes. Only one previous study examined accommodation and convergence before youth onset myopia.

METHODS

A cohort of initially emmetropic children was given eye and vision examinations at 6-month intervals for 3 years. The data collected included fusional vergence ranges at 4 m and 40 cm, and relative accommodation findings with a target at 40 cm. These clinical accommodation and vergence test findings were compared in children who became myopic (became-myopic group) to children who did not (remained-emmetropic group). The mean test findings were used to construct a zone of clear single binocular vision (ZCSBV) for each group.

RESULTS

The midpoint between the 40-cm fusional vergence range blur points was more convergent in the became-myopic group (+5.8 delta compared to +3.2 delta in the remained-emmetropic group; p < 0.004). The positive relative accommodation (PRA) finding was less in magnitude in the became-myopic group (-1.46 D) than in the remained-emmetropic group (-2.04 D), the difference being significant at he 0.02 level.

CONCLUSIONS

The ZCSBV near blur point were more convergent in the children who became myopic as indicated by the more convergent position of the midpoint of the near fusional vergence range. The lower value for the PRA test in the became-myopic group duplicates the same result reported in a previous study for retrospective longitudinal private practice data.

摘要

背景

许多近视病因理论表明,近视儿童在调节和集合方面存在差异。多项研究发现近视者和正视者在调节和集合方面存在差异。之前只有一项研究在青少年近视发病前检查了调节和集合情况。

方法

一组初始正视儿童在3年时间里每隔6个月接受一次眼部和视力检查。收集的数据包括4米和40厘米处的融合性聚散范围,以及40厘米处目标的相对调节结果。将近视儿童(近视组)与未近视儿童(正视组)的这些临床调节和聚散测试结果进行比较。使用平均测试结果为每组构建一个清晰双眼单视区(ZCSBV)。

结果

近视组40厘米融合性聚散范围模糊点之间的中点更偏向集合(近视组为+5.8棱镜度,正视组为+3.2棱镜度;p<0.004)。近视组的正相对调节(PRA)值(-1.46D)小于正视组(-2.04D),差异在0.02水平上具有统计学意义。

结论

近视儿童的ZCSBV近模糊点更偏向集合,这由近融合性聚散范围中点更偏向集合的位置表明。近视组PRA测试的较低值与之前一项回顾性纵向私人诊所数据研究报告的结果相同。
