It is frequently stated that amblyopia is not correctable after the age of 6 years. Many practitioners report marked success for older patients. To evaluate these conflicting reports, we analyzed the results from 23 published amblyopia studies. Our analysis indicates that substantial numbers of patients over age 6 were successfully treated. Success rates under age 6 were not significantly better than those in older patients when the criterion for success was achievement of 20/30 acuity or better. When a criterion of 4 lines improvement was used, success rates at all ages under 16 were quite similar; in patients 16 and over, success by this criterion was significantly less frequent, but even in this group success was achieved by 42% of the patients.
人们常说弱视在6岁之后就无法矫正了。许多从业者报告称，年龄较大的患者治疗效果显著。为了评估这些相互矛盾的报告，我们分析了23项已发表的弱视研究结果。我们的分析表明，大量6岁以上的患者得到了成功治疗。当成功标准为达到20/30或更好的视力时，6岁以下患者的成功率并不比年龄较大患者的成功率显著更高。当使用视力提高4行的标准时，16岁以下各年龄段的成功率相当相似；16岁及以上的患者，按此标准成功的频率明显较低，但即便在这个年龄组中，仍有42%的患者获得了成功。
