Corneal ulcer review proposes a mechanism-first care framework
Bottom line
Corneal ulcer review proposes a mechanism-first framework for adjunctive care
A new review in Frontiers in Veterinary Science argues that adjunctive management of canine corneal ulcers should be organized around the dominant biology driving progression, rather than ulcer appearance alone. Author Takuya Yogo proposes four therapeutic domains, structural preservation, inflammatory modulation, regenerative augmentation, and functional optimization, with “precision stratification” as a future decision-support layer. The paper positions antimicrobial therapy as essential etiologic treatment that runs alongside, not inside, this framework. In parallel, a newly published dvm360 interview with veterinary ophthalmologist Kenneth Pierce, DVM, MS, DACVO, underscores the same practical shift: targeted diagnostics, infection control, inflammation management, and a deliberate search for the underlying cause. (frontiersin.org)
Why it matters: For general practitioners and ophthalmology teams, the review offers a more structured way to think about when a corneal ulcer is primarily a protease problem, an inflammatory problem, a healing problem, or an ocular surface support problem. That could help clinicians match adjunctive therapy more intentionally, while still moving quickly on culture, cytology, broad-spectrum antimicrobials, serum, pain control, and referral when stromal loss is significant. Merck’s current guidance remains clear that infected or deep ulcers can progress rapidly, and ulcers with at least 50% stromal loss should be assessed by an ophthalmologist for possible surgical stabilization.

What to watch: Whether this conceptual model leads to prospective studies, biomarker-based stratification tools, or clearer treatment algorithms for first-opinion practice remains the next key question. (frontiersin.org)

Corneal ulcer review proposes a mechanism-first framework for adjunctive care
A newly published review in Frontiers in Veterinary Science is making the case for a different way to think about canine corneal ulcer progression. Rather than choosing adjunctive therapy mainly by ulcer morphology or severity label, author Takuya Yogo proposes a biologically organized framework that sorts interventions by the dominant processes driving tissue loss and failed healing. The framework centers on four domains, structural preservation, inflammatory modulation, regenerative augmentation, and functional optimization, with a longer-term goal of “precision stratification” using biomarkers and imaging tools that are still largely investigational in veterinary medicine. (frontiersin.org)
That idea lands at a time when corneal ulcer care remains both common and high stakes in small animal practice. Even straightforward ulcers can deteriorate quickly if infection, stromal melting, keratoconjunctivitis sicca, exposure, or mechanical irritation are missed. In a dvm360 interview published July 14, 2026, Kenneth Pierce, DVM, MS, DACVO, described a deliberately simple clinical approach: control infection, address inflammation, identify the underlying cause, document with photos, and recheck on purpose rather than assuming healing will stay on track.

In the Frontiers review, antimicrobial treatment is treated as foundational but separate from the adjunctive framework, because the paper is focused specifically on biologic modifiers of ulcer progression. Within that model, structural preservation is the highest-priority domain during active stromal melting because it aims to prevent irreversible tissue loss. The paper lists autologous serum as spanning both structural preservation and regenerative augmentation because of its anti-protease activity and epithelial support, while bandage contact lenses, hyaluronic acid lubricants, temporary tarsorrhaphy, and third eyelid flaps are grouped under functional optimization for their role in protecting the ocular surface and maintaining a healing-permissive environment.

The review is also notable for how explicitly it discusses evidence quality. It says its evidence labels are qualitative and not a formal grading system, and it acknowledges that some interventions are supported more by long-standing veterinary use and case series than by comparative trials. That transparency matters, because adjunctive corneal ulcer therapy in practice often blends established habits, specialist experience, and limited head-to-head evidence. (frontiersin.org)
Outside the paper, current reference guidance still reinforces the urgency of basics. Merck Veterinary Manual advises corneal cytology and aerobic bacterial and fungal culture with susceptibility testing for infected ulcers, alongside interim broad-spectrum topical antimicrobials, serum, mydriatics, and a systemic NSAID. It also states that ulcers with at least 50% stromal loss should be evaluated by an ophthalmologist for surgical intervention, and that deep ulcers, descemetoceles, and ruptured corneas need immediate surgical support.

Pierce’s comments in dvm360 offer a useful real-world counterpart to the review’s framework. He emphasized that thorough ophthalmic examination is often what reveals the real driver, whether that is KCS, eyelid disease, corneal contact, or another persistent insult, and he argued for timely follow-up after apparent healing to catch unresolved predisposing disease. He also described routine use of topical NSAIDs in his own cases to improve comfort, a point that may prompt discussion because anti-inflammatory choices in ulcer patients are often weighed carefully against healing concerns.

Why it matters: For veterinary professionals, the practical value of this paper is less about introducing a single new therapy and more about improving clinical reasoning. A mechanism-first framework could help teams decide whether the immediate problem is collagenolysis, inflammatory amplification, poor epithelial recovery, or an ocular surface environment that is sabotaging healing. In referral settings, that may sharpen case stratification. In general practice, it may support better decisions about when supportive care is enough, when serum or protective procedures should move up the list, and when the biology suggests the case is no longer safe to manage conservatively.

What to watch: The next step is whether this framework gets translated into prospective clinical studies, simpler treatment pathways for first-opinion clinics, or investigational tools such as tear proteomics and quantitative imaging that can identify dominant drivers earlier. Until then, the concept is likely to be most useful as a structured lens for triage and adjunctive decision-making, not a replacement for culture, close monitoring, or timely referral.
