Immunologic graft rejection in descemet's stripping endothelial keratoplasty and penetrating keratoplasty for endothelial disease.

Author information

To evaluate and compare the cumulative incidence and risk factors for first-episode immunologic graft rejection in Descemet's stripping automated endothelial keratoplasty (DSAEK) and penetrating keratoplasty (PK) and to identify potential risk factors for rejection.


Retrospective chart review.


All patients who underwent PK or DSAEK for endothelial disease at the Department of Ophthalmology, North Shore LIJ, between January 2004 and June 2010.


One hundred sixty-nine PK cases and 122 DSAEK cases were reviewed. All patients had a minimum of 3 months of follow-up, with median follow-up of 36 months in the PK group and 29 months in the DSAEK group.


Cumulative incidence of first-episode immunologic graft rejection in PK and DSAEK cohorts. Risk factors for graft rejection were reviewed.


Cumulative incidence of rejection was not significantly different between the DSAEK and PK cohorts (P<0.1324). However, among patients without glaucoma, the risk of rejection in PK was higher than that in DSAEK (hazard ratio [HR], 5.56). Prior incisional glaucoma surgery imparted a 3.15 times greater risk of rejection regardless of transplant type. Phakic patients were more likely to experience rejection than patients with a posterior chamber intraocular lens (HR, 3.23; P<0.0266), but not more likely than those with an anterior chamber intraocular lens or who were aphakic. Graft failure occurred within 6 months in 31% of PK rejections and none of the DSAEK rejections.


Descemet's stripping automated endothelial keratoplasty and PK did not show a statistically significant difference in the incidence of rejection; however, among nonglaucomatous eyes, there were significantly fewer rejections in those that underwent DSAEK.
