摘要
目的 :观察翼状胬肉与角膜散光之间的关系。方法 :应用角膜地形图仪对 34例翼状胬肉患者手术前后的角膜散光变化进行测量和分析。结果 :角膜散光度数与翼状胬肉侵入角膜的长度呈正比 ,相关系数为 0 85。胬肉主要导致顺规散光度增加。结论 :翼状胬肉通过牵拉鼻侧角膜引起顺规散光 ,散光度与胬肉长度呈正相关。手术可有效减轻角膜散光 ,改善视力。
To eveluate the relationship between pterygium and astigmatism,34 patients (34 eyes) with different sizes of pterygia were assessed and analyzed using corneal topography.There was significant statistical positive correlation between pterygium extension and astigmatism,with a correlation coefficient of 0.85,as the pterygia induce central with-the-rule astigmatic changes markedly.Surgical removal of pterygium can reduce the degree of pterygium-induced astigmatism and improve the patient’s vision.
