A review of the records of 65 patients who had surgery for congenital blepharoptosis of the upper eyelid during a three-year period revealed the preoperative presence of anisometropia, strabismus, or amblyopia in 19 patients. Postoperatively, ten of the 65 patients developed or increased their astigmatism in the operated eye. In four of these patients amblyopia attributed to this postoperative astigmatism developed. The results of our study suggest that blepharoptosis surgery done in the first few years of life may contribute to the development of astigmatism and amblyopia in some patients.
一项对65例在三年期间接受先天性上睑下垂手术患者的记录回顾显示，19例患者术前存在屈光参差、斜视或弱视。术后，65例患者中有10例手术眼出现或增加了散光。其中4例患者因术后散光导致弱视。我们的研究结果表明，在生命的最初几年进行上睑下垂手术可能会导致一些患者出现散光和弱视。
