Abstract

Purpose: The purpose of this study was to estimate the rate and review determinants of successful therapy for unilateral amblyopia in children.

Methods: This prospective cohort consisted of Saudi children aged 6-12 who received amblyopia therapy between 2020 and 2022. Best-corrected visual acuity (BCVA) in the amblyopic eye improved to reach the BCVA of the fellow eye at follow-up visits, or BCVA in the amblyopic eye improved and remained stable over three follow-up visits. Demographic and ocular characteristics were associated with the outcome.

Results: In 30 children, the median BCVA at presentation and the last follow-up was 0.8 logMAR (interquartile range [IQR]: 0.6; 1.0) and 0.45 logMAR (IQR: 0.3; 0.6), respectively. The success rate of amblyopia therapy was 80% (95% confidence interval: 65.7; 94.3). It was 100%, 76.5%, and 77.8% in eyes with anisometropic, strabismic, and mixed types of amblyopia, respectively. Amblyopia grade (P = 0.177), type of amblyopia (P = 0.96), and spectacles as therapy in the past (P = 0.09) were not significantly associated with the successful out. The duration of follow-up was significantly longer in those with unsuccessful outcomes (P = 0.05). Excellent compliance for occlusion was observed in 62.5% of children with successful outcomes. In 14 (46.7%) children, BCVA was ≤0.3 logMAR BCVA at the last follow-up. Two-line improvement in amblyopic eyes was in 26 (86.7%) children at the last follow-up compared to BCVA at presentation.

Conclusion: Occlusion therapy complemented using glasses in older children also significantly improved visual recovery in amblyopic eyes.

沙特6-12岁儿童单侧弱视的闭塞治疗效果。

目的:本研究的目的是估计儿童单侧弱视成功治疗的比率和回顾决定因素。方法:该前瞻性队列包括在2020年至2022年期间接受弱视治疗的6-12岁沙特儿童。弱视眼的最佳矫正视力(BCVA)改善，在随访时达到同眼的BCVA，或弱视眼的BCVA改善并在三次随访中保持稳定。人口统计学和眼部特征与结果相关。结果:30例患儿就诊时和最后一次随访时的中位BCVA为0.8 logMAR(四分位数间距[IQR]: 0.6;1.0)和0.45 logMAR (IQR: 0.3;分别为0.6)。弱视治疗成功率为80%(95%可信区间:65.7;94.3)。屈光参差型、斜视型和混合型弱视分别为100%、76.5%和77.8%。弱视等级(P = 0.177)、弱视类型(P = 0.96)、是否配戴过眼镜(P = 0.09)与成功出院无显著相关性。治疗不成功者随访时间明显延长(P = 0.05)。62.5%的患儿具有良好的咬合依从性。14例(46.7%)患儿在最后一次随访时BCVA≤0.3 logMAR。与首发时的BCVA相比，在最后一次随访中，26名(86.7%)儿童的弱视有两线改善。结论:遮挡治疗配合眼镜治疗可显著改善儿童弱视的视力恢复。
