“…The source of the CMV infection in these eyes is uncertain. The indications for the initial graft included keratoconus [22], posterior polymorphous dystrophy, pseudophakic bullous keratopathy [18,19], herpetic keratouveitis, Fuchs uveitis syndrome [19], Fuchs endothelial dystrophy [17], recurrent corneal endotheliitis [17] and corneal opacities [17]. Other than the eye that received a graft for keratoconus, whether these eyes already had CMV endotheliitis prior to the graft, the CMV was transmitted from the donor or the prolonged immunosuppressive therapy caused a reactivation of latent CMV, cannot be determined.…”
