A thick cornea is a constant ocular finding in the mesodermal dysmorphodystrophy (Weill-Marchesani Syndrome). In this study we investigated with confocal microscopy, the corneal structure in vivo in the patient affected by Weill-Marchesani Syndrome (WMS) in an attempt to explain the thickness increment. The corneal study showed in both eyes a highly increased central thickness with normal topography and sensitivity. The confocal examination revealed an increased evidence of keratocytes in the anterior stroma with abnormal and activated appearance. The mid and deep stroma and endothelial layer were normal. These confocal findings are a newly described feature of corneal involvement in WMS. The increase of the corneal thickness in the affected patient maybe associated with connective tissue alterations, such as abnormal collagen synthesis, that characterizes the disease.
角膜增厚是中胚层发育异常性营养不良(韦尔-马歇桑综合征)常见的眼部表现。在本研究中,我们使用共聚焦显微镜对一名韦尔-马歇桑综合征(WMS)患者的活体角膜结构进行了研究,以试图解释角膜厚度增加的原因。角膜研究显示,患者双眼中央角膜厚度显著增加,但地形图和敏感度正常。共聚焦检查发现,前基质层中角膜细胞数量增加,且外观异常并呈激活状态。角膜中层、深层基质层及内皮细胞层均正常。这些共聚焦检查结果是WMS角膜受累的一个新发现特征。患病患者角膜厚度增加可能与结缔组织改变有关,比如异常的胶原蛋白合成,这也是该疾病的特征之一。
