Urrets-Zavalia syndrome in different methods of keratoplasty.

Abstract

Urrets-Zavalia was first described as a syndrome consisting of a fixed, dilated pupil with iris atrophy following penetrating keratoplasty (PKP) in 1963 and back then it was thought that this syndrome was only related to keratoconus patients[1]. Other findings that were not essential for the diagnosis were posterior synechiae, ectropion uvea, pigment dispersion, anterior subcapsular lens opacities and secondary glaucoma syndrome[1]. Subsequently, this syndrome was described after PKP for corneal dystrophy, deep anterior lamellar keratoplasty (DALK), descemet stripping endothelial keratoplasty (DSEK), goniotomy, laser iridoplasty, iatrogenic mydriasis and after implantation of phakic intraocular lenses[2]–[8]. The present study was undertaken to report the prevalence of Urrets-Zavalia syndrome in different methods of keratoplasty.
