Risk Factors and Treatment Outcomes for Canine Spontaneous Chronic Corneal Epithelial Defects (SCCED): 335 Cases...

Area of Science:

• Veterinary Ophthalmology
• Canine Health Studies

Background:

• Spontaneous chronic corneal epithelial defects (SCCED) are a common ocular condition in dogs.
• Previous studies suggested breed and age predispositions, but lacked large-scale validation.

Purpose of the Study:

• To retrospectively evaluate risk factors, presentation, treatment, and outcomes for dogs with SCCED.
• To identify specific breeds and age groups at higher risk for SCCED.
• To compare the efficacy of different treatment modalities for SCCED.

Main Methods:

• Retrospective review of 335 dogs diagnosed with SCCED at a veterinary medical teaching hospital.
• Comparison of SCCED cases with a reference population of 157,362 dogs.
• Analysis of breed, age, weight, treatment, and outcome data.

Main Results:

• Boxers, Pembroke Welsh Corgis, and various Bulldogs were significantly overrepresented in the SCCED population.
• Dogs aged 6-15 years were overrepresented, while those younger than 5 years were underrepresented.
• Treatment success rates were 49% for cotton applicator debridement (CTA) alone, 70% for CTA + diamond burr debridement (DBD), and 66% for CTA + grid keratotomy (GK), with CTA-DBD being significantly more effective than CTA alone.

Conclusions:

• This study confirms breed predispositions (e.g., Boxers, Bulldogs) and age-related risks for SCCED using a large reference population.
• Cotton applicator debridement combined with diamond burr debridement (CTA-DBD) is a more effective treatment for SCCED than CTA alone.
