眼前段外伤与角膜内皮变化的研究

A study on the corneal endothelium after anterior segment ocular trauma

目的 探讨眼前段外伤对角膜内皮的影响。方法 应用非接触型角膜内皮显微镜对前段眼外伤病人的伤眼及其另眼 (健眼 )内皮细胞分别进行统计观察。结果 前段眼外伤特别是穿孔伤后角膜内皮细胞计数明显少于健眼。结论 前段眼外伤将导致内皮细胞大量丢失 ,并直接影响角膜的功能性修复。正确处理眼外伤将使内皮的丢失减少到最低限度。一般而言 ,前段眼外伤所导致的内皮细胞丢失对维持角膜透明性仍是安全的。

Objective To observe the affection to the corneal endothelium caused by the anterior segment ocular trauma. Methods Respectively observe the corneal endothelium of the traumatic and normal eye of the patient with the non contact specula microscope. Results The number of corneal endothelium will be decreased apparently in the anterior segment trumatic eye,especially in case of penetration. Conclusion Anterior segment ocular trauma will result in a large loss of the corneal endothelium,and influence the functional recovery of the corneal.Proper treatment is the key to prevent the endothelium from disorder,As a whole,it is safe to the corneal in mantaing its normal physiological function after ocular trauma.
