Plain-English summary
A group of research dogs had superficial corneal wounds treated with a diamond burr, a tool that helps remove damaged tissue from the eye. This method was found to be safe and effective, as it did not cause any deeper damage to the cornea beyond the outer layer. The study suggests that using a diamond burr could be a promising option for treating chronic corneal ulcers in dogs. Further evaluation in real cases is recommended to confirm its benefits.

Abstract
PURPOSE: To evaluate the corneal changes immediately after diamond burr debridement of superficial corneal wounds in dogs. Spontaneous chronic corneal epithelial defects (SCCEDs) are the most common form of canine recurrent corneal ulcers. The diamond burr has been used in the management of corneal lesions in humans since 1983. Recently, it has been successfully used in the treatment of SCCEDs in dogs; however, little has been documented as to its mechanism of action. METHODS: Five adult female research dogs euthanized for reasons unrelated to the study were included, providing 10 normal eyes. An excimer laser spatula was used for epithelial removal after delineation with an 8 mm punch biopsy trephine. Diamond burr debridement was performed for 30 and 45 s in five eyes each (groups 1 and 2 respectively). The procedure was performed on the ventral half of the experimental defect as well as ventral normal cornea, immediately after euthanasia, and prior to enucleation. Samples were processed routinely for histologic evaluation and stained with periodic acid-Schiff. RESULTS: No stromal defects could be identified under light microscopy. In experimental corneal wounds, multi-focal areas remained covered by the epithelial basement membrane (BM) after diamond burr treatment in both groups (group 1 = 48% ± 16SD, group 2 = 26% ± 12SD). Removal of BM on group 2 was significantly higher than group 1 (P < 0.05). CONCLUSIONS : The diamond burr allows a safe method of debridement and does not create defects beyond the epithelial BM in corneal wounds in normal dogs. Evaluation of the diamond burr debridement in cases of SCCEDs is warranted.
