Choroidal Thickness Changes after Orthokeratology Lens Wearing in Young Adults with Myopia.

文献摘要 INTRODUCTION

最近在韩国,有越来越多的年轻人接受角膜塑形术治疗近视眼。他们更喜欢角膜塑形治疗,而不是戴眼镜或屈光手术有几个原因。然而,目前对角膜塑形术治疗脉络膜的疗效研究较少。

OBJECTIVE

本研究的目的是分析年轻近视成人角膜塑形术后水平轴脉络膜厚度(CT)的变化。

METHODS

这是一项对19-29岁的年轻近视患者(-1.0到-5.0屈光度)的回顾性研究(n=36;23.6± 2.5年)。我们选择接受角膜塑形术治疗12个月的患者。应用光学相干断层扫描技术分析角膜塑形术治疗前后中心凹附近水平轴的CT值。在治疗开始时以及角膜塑形术治疗后3、6和12个月测量该值。分析水平面上脉络膜的三个区域,包括中心凹。

RESULT AND CONCLUSIONS

角膜塑形术治疗初期,横轴CT值为248.9± 45.7μ在时间区域,259.9米± 55.3μm在黄斑区,和219.2± 46.4μ我在鼻部。角膜塑形术治疗3个月后,3个分区脉络膜厚度值明显增加(p<0.05)。角膜塑形术治疗后6个月或12个月的平均CT大于角膜塑形术治疗前。角膜塑形术治疗3个月后,每个区域的CT均增加。青年近视患者治疗前鼻部CT较黄斑部或颞部薄。角膜塑形术治疗后观察6个月以上,CT恢复接近基线。


INTRODUCTION

Recently in South Korea, there are increasing number of young adults undergoing orthokeratology treatment for myopia control. They prefer orthokeratology treatment more than wearing spectacles or having a refractive surgery for several reasons. However, there is little research on the effect of orthokeratology treatment on choroids.

OBJECTIVE

The aim of this study was to analyze the change in choroidal thickness (CT) in the horizontal axis in young myopic adults after orthokeratology treatment.

METHODS

This was a retrospective research among young myopic patients (-1.0 to -5.0 diopters) aged 19-29 years (n = 36; 23.6 ± 2.5 years). We selected patients who were treated with orthokeratology for 12 months. CT values of the horizontal axis near the fovea before and after orthokeratology treatment were analyzed using optical coherence tomography. The value was measured at the beginning of treatment and at 3, 6, and 12 months after orthokeratology treatment. Three regional areas of choroid on the horizontal plane including fovea were analyzed.

RESULT AND CONCLUSIONS

In the beginning of orthokeratology treatment, CT of the horizontal axis was 248.9 ± 45.7 μm in the temporal region, 259.9 ± 55.3 μm in the macular region, and 219.2 ± 46.4 μm in the nasal region. Three months after orthokeratology treatment, thickness values of choroids in the 3 divided areas increased significantly (p < 0.05). Mean CT at 6 or 12 months after orthokeratology treatment was greater than before ortho<X00_Del_TrennDivis>--</X00_Del_TrennDivis>keratology treatment. CT increased after 3 months of orthokeratology treatment in each regional area. In young myopic adults, CT in nasal area was thinner than that in foveal or temporal area before treatment. CT recovered to near baseline when it was observed for more than 6 months after orthokeratology treatment.
