弱视治疗后视力回退因素分析

目的：从临床角度探讨弱视治疗后视力回退的因素。方法：对临床确诊并基本治愈的44例（77只眼）弱视患者，随访1－4年，平均2年。根据弱视的类型，治疗前弱视程度，治疗开始时年龄和巩固治疗时间进行分析。结果：44例（77只眼）中31只眼发生视力回退，回退率为40．2％。其中斜视弱视型60％发生回退，屈光参差型33％发生回退，屈光不正型12％发生回退；轻度弱视者13．3％，中度弱视者53．6％，重度弱视者83．3％发生视力回退；巩固治疗半年者38％、1年者34．8％发生回退。结论：弱视程度越重和斜视型弱视在弱视治疗成功后易发生回退，弱视治疗开始时年龄和巩固治疗时间与回退无明显关联。

Factors for deterioration of visual acuity in eyes with amblyopia after successful treatment

Objective To analyse clinically the factors for deterioration of visual acuity in eyes with amblyopia after successful treatment.Methods 44 patients(77 eyes)with amblyopia diagnosed firmly and treated succesfully were followed up 1-4 years,2 years on average.analysed according to their type,degree,age starting treatment and period time of consolidation.Results The total rate of the deterioration is 40.2%,the rate is 60% in strabismic group,33% in anisometropic group,12% in ametropic group according to their degree,the rate is 13.3% in minimal degree group,53.6% in moderate degree group.83.3% in severe degree group.assessed by period time of consolidotion,the rate is 38% in half year group.34.8% in 1 year group.58.3% in 1 year and a half group.Conclusion Low initial visual acuity and strabismic amblyopia are risk factors for deteriovation of visual acuity in eyes with amblyopia after successful treatment,there is little correlation with age starting treatment and period time of consolidation
