Presumed herpes simplex virus endotheliitis following ultra-thin Descemet's stripping automated endothelial keratoplasty.

A 78.year.old male underwent ultra.thin DSAEK for PBK (OS) and achieved BCVA 6/12 at 9 months. The patient developed allograft rejection 10 months postoperatively and was treated with IV methyl prednisolone, systemic, and topical steroids. The patient then improved and achieved 6/18 BCVA at 8 weeks. Topical prednisolone 1% twice daily was continued. Six weeks later, the patient developed fever and diminished vision and had high IOP, corneal edema, and keratic precipitates on endothelium. Considering it to as second episode of graft rejection, IV methyl prednisolone and topical steroids were given. Seeing no response, presumed HSV endotheliitis was considered as diagnosis and treated with steroids, oral acyclovir. The patient improved and achieved BCVA 6/24 with no subsequent recurrence during 11 months follow.up.
