Clinical Outcomes Following Diamond Burr Debridement of Spontaneous Chronic Corneal Epithelial Defects: A Retrospective Study of 521 Dogs.

DBD effectively treats canine SCCED; avoid NSAIDs/EDTA in French bulldogs.

This retrospective study analyzed 598 eyes from 521 dogs treated for spontaneous chronic corneal epithelial defects (SCCEDs) using diamond burr debridement (DBD) between January 2018 and May 2023. French bulldogs (21.4%), Boxers (16.4%), and Staffordshire bull terriers (8.4%) were predominantly affected. Overall success rate was 67.7% with single DBD treatment, and 61.9% achieved healing within 16 days. Complications occurred in 8.2% of cases. Multivariable analysis revealed that French bulldogs had significantly lower odds of normal healing and higher complication risk. Notably, postoperative oral NSAIDs and topical 0.2% EDTA in carbomer were associated with reduced healing odds, contrary to typical expectations. The study demonstrates that DBD is generally effective for SCCED management, but breed predisposition, particularly in French bulldogs, and specific postoperative medication choices significantly influence clinical outcomes.
