未经证实:在一些没有弱视的儿童中看到立体视力受损,斜视,和临床上显著的屈光不正。因此,可能还有其他因素影响立体敏锐度。
UNASSIGNED:这项工作的目的是研究学龄儿童局部立体视敏度的纵向变化和相关因素。
未经评估:本报告是Shahroud学童眼队列研究的一部分。目标人群是沙鲁德6至12岁的儿童,伊朗。研究的第二阶段于2018年通过重新邀请第一阶段(2015年)的所有参与者进行。经过最初的采访,研究参与者接受了验光检查和眼生物测量.使用立体飞行测试评价立体敏锐度。排除标准为功能性弱视,斜视,明显的屈光不正,两个研究阶段中任一阶段可能的眼部病理/器质性弱视,眼内手术史或眼外伤史,和不完整的数据。
UNASSIGNED:本报告分析了4666名儿童的数据,其中53.7%为男性。第二阶段研究参与者的平均年龄为12.37±1.71岁。第一阶段的平均立体视敏度为42.31(95%CI:42.05-42.57)秒弧,在第二阶段减少到51.72(95%CI:50.79-52.65)秒的电弧(P<0.001)。第一阶段立体视力不良的患病率为0.17%(95%CI:0.06-0.29),在第二阶段增加到3.94%(95%CI:3.34-4.54)(P<0.001)。根据多元线性回归,第一研究阶段年龄较大(β=0.011,P<0.001),城市住宅(β=-0.019,P=0.006),球形屈光参差增加(0.038,P=0.013),三年后,轴向长度的增加(β=0.062,P=0.003)与立体视敏度的降低(对数尺度)显着相关。
未经评估:除了已知的弱视危险因素,斜视,和显著的屈光不正,其他因素也与儿童的立体敏锐度变化有关。
Impaired stereoacuity is seen in some children without amblyopia, strabismus, and clinically significant refractive errors. Therefore, there are probably other factors affecting stereoacuity.
The aim of this work was to investigate the longitudinal changes of local stereoacuity and associated factors in schoolchildren.
The present report is a part of the Shahroud Schoolchildren Eye Cohort
Study. The target population was children aged 6 to 12 years in Shahroud, Iran. The second phase of the
study was conducted in 2018 by re-inviting all participants in the first phase (2015). After an initial interview,
study participants underwent optometric examination and ocular biometry.
Stereoacuity was evaluated using Stereo Fly Test. Exclusion criteria were functional amblyopia, strabismus, significant refractive errors, probable ocular pathology/organic amblyopia in either of the two study phases, a history of intraocular surgery or ocular trauma, and incomplete data.
The data of 4666 children were analysed for this report, of which 53.7% were male. The mean age of the studied participants in the second phase was 12.37 ± 1.71 years. The mean stereoacuity was 42.31 (95% CI: 42.05 - 42.57) seconds of arc in the first phase, which reduced to 51.72 (95% CI: 50.79-52.65) seconds of arc in the second phase (P < 0.001). The prevalence of poor stereoacuity was 0.17% (95% CI: 0.06-0.29) in the first phase, which increased to 3.94% (95% CI: 3.34-4.54) in the second phase (P < 0.001). According to the multiple linear regression, older age in the first
study phase (β = 0.011, P < 0.001), urban residence (β = -0.019, P = 0.006), increased spherical anisometropia (0.038, P = 0.013), and increased axial length (β = 0.062, P = 0.003) were significantly associated with reduction of stereoacuity (in log scale) after three years.
In addition to the known risk factors of amblyopia, strabismus, and significant refractive errors, other factors are also associated with stereoacuity changes in children.
