摘要
目的:评价准分子激光原位角膜磨镶术(LASIK)联合遮盖疗法治疗青少年屈光参差性弱视的疗效,并将其与传统光学矫正联合遮盖疗法的疗效进行比较。方法:回顾性病例对照研究,屈光参差性弱视患者19例,年龄10～17岁。A组包括患屈光参差性弱视的青少年10例,光学矫正联合遮盖疗法后,他们的视力不能改善。这些患者后接受LASIK联合遮盖疗法。B组包括年龄相匹配的屈光参差性弱视患者9例作为对照,他们适应光学矫正联合遮盖疗法。分析A组的术后视力,并与B组进行比较。结果:A组,术前平均球性屈光不正度数为-8.9±5.2D,术后为-1.9±2.0D;术前平均最佳矫正视力为0.25±0.18,治疗后提高至0.50±0.26。B组,治疗前平均最佳矫正视力为0.27±0.18,治疗后提高至0.50±0.28。两组治疗后最佳矫正视力相比较,无统计学差异。结论:对于经过传统的光学矫正联合遮盖疗法而不能提高视力的青少年屈光参差性弱视患者,LASIK为他们提供了一个可行的治疗方法,其治疗效果与传统疗法相当。
AIM： To evaluate the visual outcome of LASIK and occlusion therapy for anisometropic amblyopia in adolescents and compare it to the visual outcome of optical correction and occlusion therapy. METHODS： This retrospective case-controlled study included 19 children, aged between 10 and 17 years, with anisometropic amblyopia. Group A included 10 adolescents with anisometropic amblyopia in whom vision did not improve with optical correction and occlusion therapy. These patients were then treated with LASIK and occlusion therapy. Postoperative visual outcomes of this group were analyzed and compared to group B which included 9 age-matched controls who were compliant to treatment of anisometropic amblyopia by optical correction and occlusion therapy. RESULTS： In group A, the mean （SD） spherical refraction was -8.9 ± 5.2D preoperatively and -1.9 ± 2.0D postoperatively, the mean （ SD ） preoperative best corrected visual acuity （BCVA） was 0.25±0. 18, which improved to 0.50± 0.26 after treatment. In group B, the mean （SD） pre-treatment BCVA was 0. 27±0. 18 and improved to 0.50 ± 0.28 after treatment. There was no statistically significant difference between the two groups in terms of post-treatment BCVA. CONCLUSION： LASlK offers a feasible solution for adolescents with anisometropic amblyopia who are not improving in vision with conventional treatment optical correction and occlusion therapy. The outcome in this group was comparable to the outcome in adolescents in whom vision improved with conventional treatment.
