Abstract

Aim: To evaluate the visual outcomes of standard amblyopic treatment add-on training via perceptual learning in refractive amblyopic children and to identify the risk factors for treatment failure.

Methods: Retrospective charts were reviewed in children with refractive amblyopia who received standard treatment and add-on Cambridge Visual Stimulator (CAM) training. The add-on CAM group that was enrolled had worn full-corrected glasses for at least 2mo before training. A control group received only the standard treatment. Treatment success was defined as best-corrected visual acuity (BCVA) ≥20/25. The age, sex, initial BCVA, refractive errors, sessions and duration of training, and final BCVA were recorded.

Results: A total of 209 children (129 children in add-on CAM group and 80 children in control group) were enrolled. Seventy-six percent of unilateral and 87% of bilateral amblyopic children achieved treatment success. In children with unilateral or bilateral moderate amblyopia, the duration to reach BCVA ≥20/25 was significantly shorter in add-on CAM group than in control group. Poor initial BCVA (P<0.001) and high astigmatism (P=0.007) were risk factors for treatment failure after add-on CAM training. Age, sex, and types of refractive error were not associated with treatment success.

Conclusion: Add-on CAM training is an effective strategy for visual improvement and can shorten the treatment course when the effect of standard treatment is limited in amblyopic children.

儿童屈光性弱视的附加感知学习。

目的：评估屈光性弱视儿童通过感知学习进行标准弱视治疗附加训练的视觉效果，并确定治疗失败的风险因素：对接受标准治疗和附加剑桥视觉刺激器（CAM）训练的屈光性弱视儿童的病历进行回顾性分析。接受附加CAM训练的儿童在训练前至少已佩戴全矫正眼镜2个月。对照组只接受标准治疗。治疗成功的定义是最佳矫正视力（BCVA）≥20/25。研究记录了儿童的年龄、性别、初始BCVA、屈光不正、训练次数和持续时间以及最终BCVA：结果：共有 209 名儿童（附加 CAM 组 129 名，对照组 80 名）接受了训练。76%的单侧弱视儿童和87%的双侧弱视儿童取得了治疗成功。在单侧或双侧中度弱视儿童中，附加 CAM 组达到 BCVA ≥20/25 的时间明显短于对照组。初始BCVA较差（PP=0.007）是附加CAM训练后治疗失败的风险因素。年龄、性别和屈光不正类型与治疗成功率无关：结论：附加 CAM 训练是改善弱视儿童视力的有效策略，当标准治疗效果有限时，附加 CAM 训练可缩短疗程。
