Novel Non-Invasive Treatment for Canine Corneal Ulcers: Application of New Extracellular Matrix-Based Sticky Sealants.
Article in Veterinary ophthalmology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveTo evaluate the clinical efficacy of a newly developed adhesive tissue sealant, gelatinized cornea-derived decellularized extracellular matrix (Cod-ECM) for the treatment of stromal ulcers in dogs. ANIMAL STUDIED: This study included 60 eyes of 56 dogs diagnosed with stromal ulcerative keratitis, limited to corneal ulcers involving less than 50% of corneal thickness. PROCEDURES: Thirty eyes were treated with gelatinized Cod-ECM in combination with standard medical therapy, while the remaining eyes received conventional therapy alone. Assessments included the corneal opacity score (assessed using the semi-quantitative preclinical ocular toxicology scoring system), degree of corneal neovascularization, and time taken for complete epithelialization.
resultsComplete re-epithelialization was achieved in both the gelatinized Cod-ECM group and the Control group. The gelatinized Cod-ECM group exhibited a significant improvement in corneal opacity compared with that in the Control group (p < 0.01). Complete epithelialization occurred significantly faster in the GelCODE group (3.9 ± 0.7 days) than in the Control group (5.3 ± 1.0 days) (p < 0.01). The use of gelatinized Cod-ECM was not associated with a significant improvement in corneal vascularization compared to the Control group (p = 0.3).
conclusionsGelatinized Cod-ECM is a simple, non-invasive, and cost-effective treatment option for stromal corneal ulcers. Compared to conventional therapy, it provides superior corneal clarity and significantly accelerates epithelial healing. Although it showed no significant effect on corneal neovascularization, its ease of application and therapeutic benefits make it a promising and widely applicable approach for the management of stromal corneal ulcers in veterinary practice.
