Dear Editor,Cornealendotheliitisisacommonandintriguing clinicalentitycharacterizedbycornealedema,keratic precipitates,and mild to moderate anterior chamber reaction,which occupies the important pathogenic factor of corneal blindness[1].Robin et al[2]first described a patient who suffered from intraocular inflammation and progressive corneal endotheliitis associated with herpes simplex infection.Since then,accumulating clinical evidence confirmed that its etiology was mainly attributed to the family of herpesviridae,including herpes simplex virus,varicella zoster virus,and cytomegalovirus,which initiated the direct cell damage and immune-and inflammatory-mediated lesion on endothelial cells[1,3].
