Treatment of spontaneous chronic corneal epithelial defects (SCCEDs) with diamond burr debridement vs combination diamond burr debridement and superficial grid keratotomy.

Objective: To evaluate the efficacy of diamond burr debridement (DBD) vs a combination of diamond burr debridement with superficial grid keratotomy (DBD+SGK) for the treatment of spontaneous chronic corneal epithelial defects (SCCEDs) in dogs.

Procedure: Medical records of dogs diagnosed with SCCEDs from three different institutions that received a DBD or DBD+SGK between 2003 and 2015 were reviewed. Age, breed, sex, history of a previous SCCED, procedures performed, time to healing, and complications were statistically analyzed.
