To evaluate the morphological characteristics of posterior corneal regions including keratic precipitates in eyes with cytomegalovirus (CMV) corneal endotheliitis using anterior segment spectral domain optical coherence tomography (SD-OCT).
Thirteen eyes of 13 patients with polymerase chain reaction-proven CMV corneal endotheliitis were included in this study. Slit-lamp images and anterior segment SD-OCT images of the posterior cornea were obtained to analyze the clinical characteristics of corneal structures and keratic precipitates. Morphological changes in the posterior cornea throughout the course of an antiviral treatment were also investigated.
Anterior SD-OCT images showed protruding structures at the posterior cornea. These protruding structures exhibited dendritic, dome-shaped, quadrangular, or saw-tooth appearance, and reflectivity of these structures was high. Reflectivity of posterior corneal images including the endothelium and deep stromal corneal regions were also high (76.9%). Because corneal inflammation and corneal edema improved, the protruding structures and high-intensity regions of posterior corneal images were resolved after a course of antiviral treatment.
The anterior segment SD-OCT examination represents a useful noninvasive alternative to diagnose and monitor CMV corneal endotheliitis.
使用眼前节谱域光学相干断层扫描(SD-OCT)评估巨细胞病毒(CMV)角膜内皮炎患者角膜后段包括角膜后沉着物的形态学特征。
本研究纳入13例经聚合酶链反应证实为CMV角膜内皮炎患者的13只眼。获取裂隙灯图像和角膜后段的眼前节SD-OCT图像,以分析角膜结构和角膜后沉着物的临床特征。还研究了抗病毒治疗过程中角膜后段的形态学变化。
眼前节SD-OCT图像显示角膜后段有突出结构。这些突出结构呈树枝状、穹顶状、四边形或锯齿状外观,且这些结构的反射率较高。包括内皮和角膜深层基质区域的角膜后段图像的反射率也较高(76.9%)。由于角膜炎症和角膜水肿改善,经过一个疗程的抗病毒治疗后,角膜后段图像的突出结构和高强度区域消失。
眼前节SD-OCT检查是诊断和监测CMV角膜内皮炎的一种有用的非侵入性方法。
