摘要
目的观察角膜塑形镜控制青少年近视进展的临床效果,探讨眼轴长度是否可作为评价近视进展的有效指标。方法 66例患者,随机分为两组:角膜塑形镜组和框架眼镜组,戴镜前和戴镜后1年检查眼轴长度、眼前节长度和玻璃体腔深度,通过对比分析,评价角膜塑形术控制近视进展的作用。结果角膜塑形镜组戴镜1年后眼轴长度增长(0.24±0.05)mm;框架眼镜组增长(0.65±0.15)mm;两组比较差异有统计学意义(t=14.16,P<0.01);前者眼前节长度减少(0.02±0.02)mm;后者变化为(0.01±0.01)mm;两组比较差异无统计学意义(t=1.07,P>0.05);前者玻璃体腔深度增加(0.19±0.10)mm;后者增加(0.50±0.12)mm;两组比较差异有统计学意义(t=20.63,P<0.01)。结论角膜塑形镜可在一定程度上控制近视进展,眼轴长度和玻璃体腔深度可作为观察近视进展情况的有效指标。
Objective To observe the effect of orthokeratology leas in reducing myopia pregression in adolescents, and to discuss whether axial length is an ideal parameter for monitoring myopia progression. Methods Totally 66 cases were involved in this study. Patients were divided into 2 groups randomly. One group of subjects wear orthokeratology lens while the other group subjects wear regular spectacles. Global axial length, anterior segment depth, and vitreous cbAmher depth were evaluated before and 1 year after the treatments. Results were compared between the groups to assess the effect of orthokeratology lens. Results One year after treatments, global axial length was 0.24 ± 0. 05 mm and 0.65 ± 0. 15 mm in orthokeratdogy lens group and spectacles group respectivdy. The difference between the two groups was significant （ t = 14. 16, P 〈0.01 ）. Reduction in anterior segment depth was 0. 02 ±0. 02 mm and 0.01 ±0.01 mm respectively, and there was no difference between two groups. Increase in vitreous chamber depth was 0. 19 ± 0. 10 ann and 0. 50± 0. 12 mm respectively, and the difference between two groups was significant （ t =20.63, P 〈0.01 ）. Conduskms Orthokeratology lens can effectively reduce the progression of myopia in adolescents. Both global axial length and vitreous chamber depth can be used to monitor the progression of myopia.
