Severe and recurrent interface hemorrhage after endothelial keratoplasty.

Purpose: To report the occurrence and management of recurrent hemorrhage after Descemet stripping endothelial keratoplasty (DSEK) in a patient with pseudophakic bullous keratopathy.

Methods: An 84-year-old Chinese woman on two oral antiplatelet drugs underwent DSEK in her left eye. Preoperative best-corrected visual acuity was 20/30 OD and 14/200 OS. Intraoperative bleeding was noted from the iris root. Surgery was completed uneventfully, and interface was thoroughly irrigated in the end. Slit lamp examination on the first postoperative day showed a dense interface hemorrhage and an intraocular pressure of 24 mm Hg. Repeat interface irrigation was carried out on postoperative day 4, but the hemorrhage appeared again on the following day. Donor lenticule was well apposed to the corneal stroma, and visual acuity was hand motions in the operated eye. No further surgical interventions were performed. Corticosteroid eye drops were continued four times a day in the operated eye, and the patient was advised weekly follow-up.

Results: Over the next 4 weeks, the interface blood gradually started to clear from the central cornea. At the end of 4 months postoperatively, the interface hemorrhage disappeared completely. A final best-corrected visual acuity of 20/80 was achieved. Specular microscopy revealed an endothelial cell density of 1375 cells/mm2.

Conclusions: Interface hemorrhage is a known complication after DSEK surgery. Recurrent hemorrhage may be expected in patients on oral antiplatelet treatment. In cases without associated graft dislocation, conservative management can still result in good visual outcome.
