翼状胬肉患者屈光状态的检测

Examination and analysis of refractive status of patients with pterygium

目的 :探讨翼状胬肉患者的特殊屈光状态。方法 :对 40例 6 2眼翼状胬肉患者进行视力检查、主客观屈光度检查、角膜曲率检查和翼状胬肉侵入角膜的长度测量。结果 :5 0眼裸眼视力在 0 .4以上 ;5 7眼均有不同程度的散光 ,其散光程度与胬肉长度有关 ,其中顺规性散光 33眼 (占 5 7.9% ) ,远视性散光 36眼 (占 6 3.2 % ) ;5 0眼 (80 .6 % )矫正视力在 0 .8以上。综合验光、检影验光得出的散光度与电脑验光得出的散光度差异有显著性。结论 :翼状胬肉患者的角膜散光以顺规性散光和远视性散光为主 ,翼状胬肉的长度与散光关系较为密切 ,其散光度的检查应该以检影验光和规范的主觉验光为准 ,配戴矫正的框架眼镜可提高翼状胬肉患者的视力 。

Objective:To explore the refractive state of patients with pterygium.Methods:40 patients(62 eyes) with primary pterygium were evaluated. Refraction,corneal curvature measurement and pterygium size measurement were used for the evaluations.Results:Visual acuity for 50 eyes was better than 0.4. Pterygium can induce various levels of astigmatism;the level is correlated to the size of the pterygium. 33 eyes(57.9%) had with-the-rule astigmatism and 36 eyes(63.2%) were hyperopic. The corrected VA for 50 eyes(80.6%) was better than 0.8. The results from subjective refraction and retinoscopic refraction measurements were significantly different from the results of auto refraction.Conclusion:Once pterygium reaches a critical size,it induces significant hyperopia and with-the-rule astigmatism. The values from retinoscopy and subjective refraction measurements were more accurate than autorefraction. VA can be improved and fatigue can be alleviated by wearing spectacle corrections.
