Purpose
To investigate the incidence of intraocular pressure (IOP) elevation after Descemet’s stripping endothelial keratoplasty (DSEK) and associated clinical findings.
Methods
Forty-eight eyes of 46 patients who underwent DSEK were studied in this single-center retrospective study. IOP elevation was defined as the presence of an increase in IOP above 21 mmHg lasting at least two months, the need to introduce topical/oral antiglaucoma medications for at least two months, and the need for surgical therapy for uncontrolled IOP. Patients with pre-existing glaucoma or patients who were using antiglaucoma drugs before DSEK were excluded according to the protocol of the study. The incidence of post-DSEK IOP elevation was investigated.
Results
The incidence of IOP elevation after DSEK was 16.7 %. Glaucoma therapy following DSEK was needed in eight eyes of eight patients. IOP elevations were diagnosed from two to ten months after DSEK. There was no statistical difference in the survival probabilities of patients with different preoperative diagnoses. Pre-op IOP was observed to be a risk factor of IOP elevation in this series.
Conclusions
IOP elevation appears to be a common postoperative complication of DSEK. Patients without preexisting glaucoma but with higher pre-op IOP need to be followed up carefully after DSEK.
