Purpose: To investigate the influence of retinal photocoagulation with an indirect ophthalmoscopy contact lens on corneal endothelial cells.Methods: Seventeen eyes of 17 patients were evaluated, and corneal endothelial cells were measured twice: just before retinal photocoagulation using an indirect ophthalmoscopy contact lens and 33.2 ± 10.2 days after surgery.

为研究采用间接检眼镜接触镜进行视网膜激光光凝对角膜内皮细胞的影响，对17例患者的17眼进行检测并对角膜内皮细胞检测两次：视网膜激光光凝术前和术后33.2±10.2天检测。

Results: A statistically significant reduction was found in corneal endothelial cell numbers before versus after surgery ( P=0.0003).Conclusion: Our results show corneal endothelial cells to be decreased by retinal photocoagulation with an indirect ophthalmoscopy contact lens.

结果显示：术前与术后角膜内皮细胞数目比较有明显的差异，提示采用间接检眼镜接触镜进行视网膜激光光凝使角膜内皮细胞减少。
