To assess the effects of refraction and axial length on optical coherence tomography (OCT) measures of childhood optic disk parameters.
Population-based cross-sectional study.
Of 4,118 children examined in the Sydney Myopia Study (Sydney Childhood Eye Study) from 34 randomly selected primary schools and 21 secondary schools from 2003 through 2005, 3,529 (85.7%) were included in the analysis (1,395 6-year-old children [year 1 students] and 2,134 12-year-old children [year 7 students]). Comprehensive standardized eye examinations included best-corrected visual acuity, cycloplegic autorefraction, biometry measurements, and fast optic disk scans using OCT.
After adjusting for magnification, the mean optic disk area was positively associated with axial length (P(trend) < .0001, both age groups) but was not associated consistently with spherical equivalent refraction (SER).
Optic disk parameters in childhood are influenced by axial length, but not by refractive error itself.
评估屈光和眼轴长度对儿童视盘参数光学相干断层扫描(OCT)测量结果的影响。
基于人群的横断面研究。
在2003年至2005年期间,从34所随机选取的小学和21所中学中选取4118名儿童参与悉尼近视研究(悉尼儿童眼研究),其中3529名(85.7%)纳入分析(1395名6岁儿童[一年级学生]和2134名12岁儿童[七年级学生])。全面的标准化眼科检查包括最佳矫正视力、睫状肌麻痹验光、生物测量以及使用OCT进行快速视盘扫描。
在调整放大率后,平均视盘面积与眼轴长度呈正相关(P趋势<.0001,两个年龄组均如此),但与等效球镜度(SER)无一致关联。
儿童期视盘参数受眼轴长度影响,但不受屈光不正本身影响。
