To investigate the usefulness of daily-wear opaque contact lens treatment for older children with amblyopia.
A retrospective chart review of all children undergoing opaque contact lens therapy for amblyopia between 2000 and 2003 was performed. All patients were included except for those younger than 5 years of age, those undergoing maintenance treatment only, those lost to follow-up, or those unable to cooperate with Snellen visual acuity testing.
Thirteen children were identified, and seven met the inclusion criteria. The seven patients had a mean age of 7.5 years (range, 5.7-8.7 years). The causes of amblyopia were anisometropia (five patients), cataract (one patient), and strabismus (one patient). For all seven patients, the mean logMAR improvement in visual acuity was 0.52 (range, 0.26-1.22). The average duration of opaque contact lens use was 9.3 months (range, 2-21 months). Compliance problems were encountered in three patients. No major complications occurred, but one patient had an episode of mild superficial punctate keratitis.
Daily-wear opaque contact lens treatment is a useful occlusion method for amblyopia treatment in older children with various practical and social impediments to skin patching. Meaningful improvement in visual acuity can be obtained, even in children older than 8 years of age.
探讨日戴型不透明隐形眼镜治疗大龄弱视儿童的有效性。
对2000年至2003年间所有接受不透明隐形眼镜治疗弱视的儿童进行回顾性病历审查。除5岁以下儿童、仅接受维持治疗的儿童、失访儿童或无法配合斯内伦视力测试的儿童外，所有患者均纳入研究。
共确定13名儿童，其中7名符合纳入标准。这7名患者的平均年龄为7.5岁（范围5.7 - 8.7岁）。弱视原因包括屈光参差（5例）、白内障（1例）和斜视（1例）。所有7名患者的视力平均logMAR改善值为0.52（范围0.26 - 1.22）。不透明隐形眼镜的平均使用时长为9.3个月（范围2 - 21个月）。3例患者出现依从性问题。未发生重大并发症，但1例患者出现轻度浅层点状角膜炎。
对于因各种实际和社会因素而无法进行眼罩遮盖治疗的大龄弱视儿童，日戴型不透明隐形眼镜治疗是一种有效的遮盖方法。即使是8岁以上的儿童，也能在视力上取得有意义的改善。
