文献摘要 BACKGROUND

本研究的目的是监测新加坡近视儿童配戴角膜塑形术12年后的屈光、地形和生物特征变化 月。

METHODS

从新加坡的一家验光诊所,回顾性收集了亚洲人群62只眼经角膜塑形术矫正后的近视资料。用Pentacam分析眼前节参数。治疗前、治疗后1晚、1周、1、3、6、12个月用IOLMaster测量眼轴长度,通过主观检查评价屈光度 月。建立logistic回归模型,评估慢(<0.10)的概率 mm/年)或更快的眼睛生长(≥ 0.10 毫米/年)。

RESULTS

受试者的平均年龄为12.2岁 ± 3.9 年(范围5-19 71%是女性。基线近视为-3.95 ± 1.59 D(范围 -1.50和 -8.75天)。12个月后有显著性差异 屈光不正治疗月数、角膜中央前表面参数(曲率和高度)和角膜中央厚度。地形和厚度变化稳定后一周的治疗。在12 角膜塑形术治疗6个月后,眼轴长度显著增加(差异=0.11) ± 0.18 嗯,p < 0.001),而折射保持稳定。11岁以上受试者轴长变化 年数与基线近视无统计学意义的独立性,基线近视大于4.00d的受试者。Logistic回归分析显示,每增加一岁和每增加一个屈光度,基线近视眼眼眼轴延长的概率降低(优势比[OR]=1.23,2.19,95%CI;OR分别为1.08、3.47和95%CI)。

CONCLUSION

角膜塑形术治疗1周后角膜参数稳定,尤其是4.00d以下的近视眼。年龄大于11岁的儿童中轴长度没有明显变化 岁或近视眼4.00天以上接受角膜塑形术治疗的受试者。


BACKGROUND

The aim of this study was to monitor refractive, topographic and biometric changes in Singaporean myopic children fitted with orthokeratology over a period of 12 months.

METHODS

Data from 62 myopic eyes from an Asian population corrected with orthokeratology were retrospectively collected from an optometric clinic in Singapore. Anterior segment parameters were analysed with a Pentacam. Axial length was measured using the IOLMaster and refraction was assessed by subjective examination before the treatment and after one night, one week, and one, three, six and 12 months. A logistic regression model was built to evaluate the probability of slower (< 0.10 mm/year) or faster eye growth (≥ 0.10 mm/year).

RESULTS

Subjects had a mean age of 12.2 ± 3.9 years (range 5-19 years), and 71 per cent were female. Baseline myopia was -3.95 ± 1.59 D (range -1.50 and -8.75 D). Statistically significant differences were found after 12 months of treatment for refractive error, parameters of the central anterior corneal surface (curvature and elevation) and central corneal thickness. Topographic and thickness changes stabilised after one week of treatment. During 12 months of orthokeratology treatment there was a significant increase of axial length (difference = 0.11 ± 0.18 mm, p < 0.001) while refraction remained stable. Changes in axial length of subjects above 11 years were not statistically significantly independent of the baseline myopia, and in subjects with baseline myopia greater than 4.00 D. Logistic regression showed that each additional year of age and each additional dioptre of baseline myopia decreased the probability of faster axial elongation (odds ratio [OR] = 1.23, 2.19 95% CI; OR = 1.08, 3.47 95% CI, respectively).

CONCLUSION

Corneal parameters in orthokeratology treatment were stable after one week, particularly for myopes under 4.00 D. Axial length did not change significantly in children older than 11 years of age or in subjects with myopia above 4.00 D undergoing orthokeratology treatment.
