Healing Outcomes and Complications of Spontaneous Chronic Corneal Epithelial Defects in French Bulldogs Following Diamond Burr Debridement and Bandage Contact Lens Placement Compared to a Population of Non-French Bulldogs.

French bulldogs develop SCCEDs younger with longer healing times and increased complications.

This retrospective multi-center study compared spontaneous chronic corneal epithelial defect (SCCED) outcomes in French bulldogs versus other breeds following diamond burr debridement and bandage contact lens placement (DBD/BCL). The analysis included 332 SCCEDs (119 from 100 French bulldogs, 213 from 188 other breeds) treated between January 2020 and December 2024. French bulldogs presented at significantly younger mean age (6.3 vs 8.9 years, p<0.001) and demonstrated longer median healing times (21 vs 16 days, p<0.001). While single-procedure success rates were similar (83% vs 89%, p=0.153), French bulldogs experienced significantly higher complication rates including corneal infection, subepithelial bullae formation, exuberant granulation tissue, and pigment deposition (p<0.001). These findings suggest breed-specific differences in SCCED pathophysiology and treatment response, with French bulldogs representing a distinct clinical population requiring potentially modified therapeutic approaches or enhanced monitoring protocols.
