Purpose : To evaluate the outcome of partial thickness corneal patch grafts for exposed glaucoma drainage devices (GDD).

Methods : In this retrospective interventional study all patients who had an exposed GDD underwent a revision surgery using partial thickness corneal patch graft. Non-optical quality cornea was used in all patients. The patients were followed up for a minimum of one year. The patient profile, surgical success rate and any complications were recorded. A tectonic graft success was considered when there was no melting.

Results : Thirty three patients (mean age 69.9 ± 12.2 years) were enrolled. GDD was implanted primarily for primary open angle glaucoma in 90.9% patients. Majority of these implants were Ahmed glaucoma valves (93.9%). All patients underwent lamellar corneal patch grafting to cover the exposed GDD. The average follow-up period was 24.2 ± 14.3 months. Corneal patch graft had provided excellent cosmetic appearance.
Graft melting occurred in 3 patients (9.09%) who eventually needed repeat graft.

Conclusions : Corneal patch graft following exposed GDD provided reasonable therapeutic success and excellent cosmetic appearances.
