New Therapy Effective for Resistant Eye Infections in Pets

📅 Jun 25, 2026 · Veterinary ophthalmology

Background Information

Pioneering therapy heals resistant eye infections in pets quickly and safely.

Rose Bengal Photodynamic Antimicrobial Therapy (RB-PDAT) could offer a new treatment option for infectious keratitis in companion animals that is resistant to standard therapies. In 22 cases of refractory infectious keratitis, full epithelialization occurred within 30 days, with median healing in dogs at 9 days and mean healing in cats at 14 days. RB-PDAT was effective without adverse effects or need for surgery, suggesting it may reduce antibiotics reliance, but further studies are required for broader veterinary application. RB-PDAT shows promise in treating refractory infectious keratitis in pets, avoiding surgery and minimizing antibiotic use.
