Abstract

Abstract : Purpose: Our aim was to compare changes in intraocular pressure (IOP) and management of glaucoma in patients undergoing either penetrating keratoplasty (PK) or Descemet stripping endothelial keratoplasty (DSEK). Method: A retrospective review of all patients who underwent primary corneal transplantation at Sydney Eye Hospital (Sydney, Australia) from January 2008 to December 2010 was performed. Eyes with comparable indications and either primary PK or DSEK with 12 months of follow-up were included. Data on IOP and antiglaucoma management postoperatively were collected. An IOP elevation of ≥30% from baseline or an absolute IOP of >24 at 1 year postoperatively was significant. Results: Sixty-one eyes from 61 patients met the inclusion criteria. Comparable eyes had undergone either PK (n=28, 46%) or DSEK (n=33, 54%). In patients without prior glaucoma (n=39), 29% of those in the PK group and 28% in the DSEK group required a change in therapy to control IOP ( P =0.970). If there was prior glaucoma (n=22), the PK group required a change in 71% of patients compared with the DSEK group, 63% ( P =0.665). In both groups of patients, PK and DSEK, elevation of IOP of at least 30% from baseline to 1 year was seen in 39% ( P =0.993) regardless of glaucoma status. Conclusions: Elevation of IOP is a serious consequence of both PK and DSEK, even despite maximal medical therapy in certain cases. DSEK has an equivalent incidence of IOP elevation to PK in comparable patients. Careful monitoring of IOP and appropriate therapy should be instituted to prevent progression to glaucoma.
