BACKGROUND
Eyes with tears in Descemet's membrane secondary to forceps injuries frequently develop myopic astigmatism. Little is known regarding the longitudinal changes in the refractive errors of these eyes.
METHODS
We performed a retrospective review of two children with tears in Descemet's membrane following forceps injuries to their left eyes. The refractive errors were followed longitudinally.
RESULTS
Both patients developed myopic astigmatism in their affected eye and received optical correction and occlusion therapy. In both cases there was reduction in the myopic refractive error during early childhood. While the astigmatic refractive error was stable in one patient it decreased in the second patient.
CONCLUSION
Myopia decreased in two children with myopic astigmatism secondary to tears in Descemet's membrane. Myopia in children with tears in Desemet's membrane is likely due to deformation of the cornea rather than form-deprivation.
背景
因产钳损伤导致后弹力层出现撕裂的眼睛常常会发展为近视性散光。对于这些眼睛屈光不正的纵向变化了解甚少。
方法
我们对两名左眼因产钳损伤导致后弹力层撕裂的儿童进行了回顾性研究。对其屈光不正情况进行了纵向追踪。
结果
两名患者患眼均出现了近视性散光，并接受了光学矫正和遮盖治疗。在两例病例中，幼儿期近视屈光不正度数均有所降低。其中一名患者的散光屈光不正度数稳定，而另一名患者的散光度数则有所下降。
结论
两名因后弹力层撕裂继发近视性散光的儿童近视度数降低。后弹力层撕裂患儿的近视可能是由于角膜变形而非形觉剥夺所致。
