“…Subsequent experimental evaluation of the DBD technique in laboratory rabbits demonstrated that DBD was effective in removing epithelium and in partial removal of the underlying basement membrane and that wounds created by DBD healed more quickly than those created using lamellar keratectomy utilizing a scalpel blade 19 . Since that time, a number of studies have evaluated DBD for the treatment of superficial corneal erosions and dystrophic epithelial irregularities 20–27 . A meta‐analysis of four studies revealed an overall success rate of 94% 21 .…”

Objective To describe the outcome of canine spontaneous chronic corneal epithelial defects (SCCED) treated with diamond burr debridement (DBD) and bandage contact lens placement (BCL). Animal studied Forty eyes of 36 dogs presenting to a single private practice. Procedures A retrospective review of medical records was performed. Cases were eligible for inclusion if they were newly diagnosed with SCCED by a veterinary ophthalmologist and treated with DBD/BCL. All patients received a complete ocular examination followed by DBD using a battery-powered, handheld motorized burr (Algerbrush(®) , Alger Equipment Company, Lago Vista, TX, USA). A BCL was placed post-debridement in all patients. Data were analyzed for sex, age, breed, duration of clinical signs prior to DBD; number of debridements required before healing was achieved; contact lens retention, complications attributed to DBD, and additional surgical interventions were required to achieve healing. Results The median time to first recheck examination was 7 days (IQR 7-9 days) with 28/40 (70%) of cases healed at this examination. The mean time to second recheck examination was 15.5 ± 5.5 days with 37/40 (92.5%) healed by this examination. The median time to final recheck examination was 19 days (IQR 18-35.5 days) with a range of 18-52 days. All cases resolved by the third and final recheck examination. A second DBD/BCL was performed in 5/40 (12.5%) of cases. The BCL retention rate was 95% over all examination time points. No case required a keratectomy or other surgical intervention to achieve healing. The only complication observed was one case of suspected bacterial keratitis post-DBD/BCL. Conclusions Results suggest that DBD/BCL is safe and effective for treatment of canine SCCED.

“…The diamond burr treatment is now considered a safe and simple outpatient procedure in humans; it has a high success rate, requires only topical anesthesia and is low cost, providing an excellent treatment modality for the treatment of indolent ulcers 8,10,25,27,32 . Additionally, it causes minimal refractive shifts 25,32 or permanent corneal scarring 25,27,32 …”

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.

“…Epithelial debridement, with or without diamond burr polishing of Bowman layer, is a safe and effective procedure preferred by many corneal specialists for its excellent results and its ease of performance at the slit-lamp or in the minor procedure room. [6][7][8][9][10][11][12][13][14] The purpose is to mechanically remove the re-duplicated basement membrane and devitalised epithelium so that new epithelium may migrate in and form a smoother surface. earlier recovery of corneal transparency and epithelial innervation.…”

“…12 Another study using diamond burr polishing for visually significant EBMD also did not observe any recurrences, although the mean follow-up was only 10.6 months. 8 In a prospective, double-masked, randomised, controlled trial, Wong and colleagues investigated debridement techniques in 48 patients with recurrent erosion syndrome secondary to EBMD or trauma. 13 Patients received either simple epithelial debridement with cellulose sponge or epithelial debridement with diamond burr polishing and superficial keratectomy.…”

Epithelial Debridement for Epithelial Basement Membrane Abnormalities Associated with Endothelial Disorders

Epithelial basement membrane dystrophy (EBMD) is a corneal condition most commonly observed as a primary disease; less commonly it can also be seen as secondary to endothelial cell dysfunction. Epithelial debridement with or without polishing of the Bowman layer is a safe and effective way of removing the dystrophic basement membrane and promoting a smoother epithelial surface. Indications for debridement include symptoms of recurrent corneal erosions and vision loss attributable to epithelial irregularity. In this article we also present follow-up data on patients for whom we have previously performed epithelial debridement for EBMD in the setting of Fuchs endothelial dystrophy and iridocorneal endothelial syndrome, with favourable visual outcomes. We also present two new cases of EBMD that limited visual acuity after Descemet stripping automated endothelial keratoplasty, who responded successfully to epithelial debridement.
