Two sets of monozygotic twins with mirror image myopic anisometropia are reported. The first set were two boys aged 1 year 8 months. There was a right eye myopic anisometropia in one twin, and a left eye myopic anisometropia in the other. The differences in refractive power between both eyes were 11.6 and 7.6 dpt, respectively (spherical equivalent). The second set were two 6-year-old boys. The right eye had myopic anisometropia in one twin, while the left eye was affected in the other. The differences in refractive power between both eyes were 6.5 and 3.7 dpt, respectively (spherical equivalent). Exotropia was recognized in 3 cases. Previously only two sets of monozygotic twins with mirror image myopic anisometropia have been reported. Monozygotic twins with mirror image myopic anisometropia are extremely rare.
本文报告了两组患有镜像性近视性屈光参差的同卵双胞胎。第一组是两个1岁8个月大的男孩。其中一个双胞胎右眼患有近视性屈光参差，另一个则是左眼患有近视性屈光参差。双眼屈光力差异分别为11.6和7.6屈光度（等效球镜）。第二组是两个6岁的男孩。其中一个双胞胎右眼患有近视性屈光参差，而另一个则是左眼受影响。双眼屈光力差异分别为6.5和3.7屈光度（等效球镜）。3例患者被诊断为外斜视。此前仅有两组患有镜像性近视性屈光参差的同卵双胞胎被报道。患有镜像性近视性屈光参差的同卵双胞胎极为罕见。
