摘要
背景:过度矫正负镜片的基础是诱导顺应性,从而防止持续性外斜视。以前的一些研究提倡早期手术治疗,而另一些研究则建议过度治疗。我们的目的是评估超负镜片的成功率。方法:本描述性横断面研究对106名7岁以下间歇性外斜视(IXT)患者进行,这些患者在伊朗吉兰医学科学大学Amir Al Momenin医院就诊。数据通过表格收集,包括性别、年龄、睫状肌麻痹屈光度、使用超负眼镜前后的偏差量、视力、超负眼镜的数量、治疗持续时间、恢复和随访。成功率被定义为将外斜视降低到10棱镜屈光度以下或外斜视。结果:本研究共纳入106名患者,平均年龄2.25±0.74岁。治疗前后的平均外斜视分别为20.96±8.20和12.16±11.04棱镜屈光度,差异有统计学意义(P<0.002),平均球面屈光度和散光误差(睫状肌麻痹屈光度)分别为+1.34±1.07和-0.32±0.72屈光度。随访结束时,5.6%的患者外斜视增加,15%的患者无变化,平均偏差为25.0±6.06棱镜屈光度,79.24%的患者治疗成功。结论:根据本研究的结果,过度矫正晶状体治疗IXT是一种安全有效的预防外斜视的方法。
Role of Overcorrecting Minus Lens Therapy in Intermittent Exotropia for Prevention of Constant Exotropia in Children Under the Age of 7 Years.
Background: The basis of the overcorrecting minus lens is to induce compliance and consequently prevent constant exotropia. Some previous studies advocated early surgical therapy and others suggested over-minus treatment. Our purpose is to evaluate the success rate of the over-minus lens.
Methods: This descriptive cross-sectional study was carried out on 106 patients under the age of 7 years with intermittent exotropia (IXT) who attended Amir-Al-Momenin Hospital at Guilan University of Medical Sciences, Iran. The data was gathered by a form including sex, age, level of cycloplegic refraction, the amount of deviation before and after using the over-minus glasses, visual acuity, the amount of the over-minus glasses, duration of treatment, recovery, and follow-up. The success rate was defined as decreasing exotropia to less than ten prism diopters or exophoria.
Results: A total of 106 patients with a mean age of 2.25 ± 0.74 years were enrolled in this study. The mean exotropia before and after treatment was 20.96 ± 8.20 and 12.16 ± 11.04 prism diopters, respectively, and there was a statistically significant difference (P < 0.002). The mean refractive spherical and astigmatic errors (cycloplegic refraction) were +1.34 ± 1.07 and -0.32 ± 0.72 diopters, respectively. At the end of the follow-up, exotropia increased in 5.6% of patients, there was no change in 15% of patients with a mean deviation of 25.0 ± 6.06 prism diopters, and 79.24% of patients were treated successfully.
Conclusions: According to the results of this study, treatment of IXT by over-correcting lenses can be a safe procedure and effective in preventing exotropia.
