Abstract

Purpose: To investigate the correlation between intracellular dark endothelial spots (IDESs) detected by specular microscopy and the incidence of graft failure after Descemet's membrane endothelial keratoplasty (DMEK).

Methods: We reviewed 100 consecutive DMEK patients performed by a single surgeon at two centres between January 2015 and July 2022. Central corneal thickness was evaluated using anterior segment optical coherence tomography (SS-1000; Tomey, Aichi, Japan), and endothelial cell density was measured using specular microscopy. Kaplan-Meier estimates and Cox regression models were used to evaluate graft failure and associated risk factors.

Results: Of the 97 eyes included, 9 experienced graft failure within the follow-up period (52.9 ± 23.9 months). IDES presence significantly correlated with decreased endothelial cell density and higher graft failure rates (hazard ratio = 4.68, 95% confidence interval = [0.96, 22.7], P = 0.034).

Conclusion: IDESs represent a significant risk factor for graft failure post-DMEK. Careful postoperative management is imperative to minimise this risk.

利用镜面显微镜检测到的细胞内暗内皮斑点与Descemet膜内皮角膜移植术后移植失败有关。

目的：探讨Descemet膜内皮角膜移植术（DMEK）后细胞内暗内皮斑点（IDESs）与移植失败发生率的关系。方法：我们回顾了2015年1月至2022年7月期间由一名外科医生在两个中心连续手术的100例DMEK患者。采用前段光学相干断层扫描(SS-1000；Tomey，爱知，日本)，内皮细胞密度用镜面显微镜测量。Kaplan-Meier估计和Cox回归模型用于评估移植物衰竭和相关危险因素。结果：97只眼中，9只眼在随访期间（52.9±23.9个月）出现移植失败。IDES的存在与内皮细胞密度降低和移植失败率升高显著相关（风险比= 4.68,95%可信区间= [0.96,22.7],P = 0.034）。结论：IDESs是dmek后移植物衰竭的重要危险因素。仔细的术后管理是减少这种风险的必要条件。

期刊介绍： Graefe''s Archive for Clinical and Experimental Ophthalmology is a distinguished international journal that presents original clinical reports and clini-cally relevant experimental studies. Founded in 1854 by Albrecht von Graefe to serve as a source of useful clinical information and a stimulus for discussion, the journal has published articles by leading ophthalmologists and vision research scientists for more than a century. With peer review by an international Editorial Board and prompt English-language publication, Graefe''s Archive provides rapid dissemination of clinical and clinically related experimental information.
