New slit-lamp technique can drain interface fluid in post-DSEK disc detachments

A new slit-lamp technique for draining interface fluid can be used to successfully manage donor disc detachments in eyes treated with Descemet's stripping endothelial keratoplasty, according to a small study by Canadian researchers.
Sathish Srinivasan, FRCSEd, FRCOphth, and David S. Rootman, MD, FRCSC, of Toronto Western Hospital, evaluated outcomes for five patients who developed complete donor lenticule detachment 1 day after undergoing Descemet's stripping endothelial keratoplasty (DSEK).
"Slit-lamp biomicroscopy showed interface fluid preventing attachment of the donor disc to the host stromal bed," the authors noted.
Surgeons treated the patients at the slit lamp. The technique involved completely filling the anterior chamber with an air bubble using a 30-gauge needle on a 3 mL syringe. The inferior mid-peripheral corneal drainage slit was then opened using 0.12 forceps, and the fluid was drained, the authors reported.
"This technique was successful in draining the interface fluid in all five patients, leading to immediate complete reattachment of the donor disc," they said.
The study is published in the September issue of British Journal of Ophthalmology.
