PURPOSE
Astigmatic changes induced by the pterygium and their relation to its size and morphology were analysed to establish the critical size for surgery before significant astigmatism occurs.
MATERIALS AND METHODS
We evaluated the refraction in 148 eyes of 108 adult patients with primary pterygia. We grouped the astigmatic values according to the keratometric results correlating with the maximal length, width and the approximate total area of the pterigium encroaching on the corneal surface.
RESULTS
Pterygia with length or width > or = 3.00 mm were related to significantly higher astigmatism than other groups (p<0.01). The effect of the pterygium morphology on corneal astigmatism was not significant.
CONCLUSIONS
Pterygia exceeding 3.00 mm of length or width should be considered within the limits of surgery.
目的
分析翼状胬肉引起的散光变化及其与翼状胬肉大小和形态的关系，以确定在出现明显散光之前进行手术的临界大小。
材料与方法
我们评估了108例患有原发性翼状胬肉的成年患者的148只眼睛的屈光情况。我们根据与侵犯角膜表面的翼状胬肉的最大长度、宽度和大致总面积相关的角膜曲率计结果对散光值进行分组。
结果
长度或宽度≥3.00mm的翼状胬肉与明显更高的散光相关，高于其他组（p<0.01）。翼状胬肉形态对角膜散光的影响不显著。
结论
长度或宽度超过3.00mm的翼状胬肉应在手术范围内予以考虑。
