摘要
翼状胬肉是一种常见的眼表疾病。翼状胬肉通过对角膜的牵拉压迫作用、局部泪膜的透镜作用、角膜组织的瘢痕作用等来改变角膜的屈光状态。而翼状胬肉所引起的角膜散光大小则与胬肉侵入角膜的长度、宽度、深度,手术次数,活动隆起情况等因素相关。该文就翼状胬肉引起角膜屈光状态改变的机制及胬肉中影响角膜散光大小的因素予以综述。
Pterygium is a common ocular surface disorder, which changes corneal refraction by the stretch and stress to cornea, partial tear film len fuction, and corneal stromal layer scar. Corneal astigmatism is associated with the length,width, depth by the intrusion of pterygium, and also operation times, activity and uplift of pterygium. Here is to make a review of the mechanism of corneal refraction caused by pterygium,and the influencing factors of corneal astigmatism.
