Abstract
Section titled “Abstract”Abstract Objective To describe the clinical outcomes and efficacy of diamond burr debridement (DBD) treatment for corneal ulceration in cats. Procedure(s) Medical records of cats that received DBD at two private practices between 2015 and 2021 were retrospectively reviewed. DBD was performed using a battery‐powered, handheld motorized burr and a bandage contact lens was placed in 18/21 eyes. Corneal ulceration was considered resolved if the cornea was fluorescein negative with a stable epithelial surface. Recurrence was defined as return of corneal ulceration. Descriptive statistics and a Fisher’s exact test were conducted on the study population. Results Twenty‐one eyes from 20 cats with superficial corneal ulcers refractory to medical treatment underwent DBD. Domestic and Burmese were the most commonly encountered breeds and the median age of affected cats was 8.83 years (range 0.5-20 years). Corneal ulceration was present for a median of 14 days prior to DBD. Healing was achieved in 81% of eyes; with four eyes failing to heal and requiring further intervention. Corneal sequestrum was reported in one case that failed to heal. Of the healed cases, three cases recurred (17.6%) at a mean of 116.3 days (range 79-135 days). Burmese were overrepresented ( p < .001) in cases that failed to heal or recurred (6/7 eyes; 85.7%). The median postoperative follow‐up time was 93 days (range 6-1613 days). Conclusions Diamond burr debridement is a safe, non‐invasive treatment for corneal ulceration in cats but, compared with published results, it had a lower success rate than superficial lamellar keratectomy.
