United States: Recent research indicates that new eye drops designed for dogs hold greater potential to help fight infections, according to scientific findings.
New Study Reveals Potent Eye Treatment for Dogs
A new study in Veterinary Ophthalmology demonstrated that hyaluronic acid eyedrops provided superior coverage of antibiotics on the eyes of healthy canine subjects compared to regular eyedrop preparations, as reported by HealthDay.
The research showed that antibiotics maintained higher concentrations in the canine eye for longer durations through this experiment, which could enhance the drops’ ability to fight infections, according to the scientists involved.
Further testing is needed to evaluate these drops when applied to dogs that actually have eye infections. Research predicting this eye treatment could benefit human patients with eye conditions.
Dogs: A Closer Match to Humans
“The findings of this study offer clear benefits for our veterinary patients, but they also carry translational relevance for human medicine,” said senior researcher Dr. Lionel Sebbag, an ophthalmologist at Hebrew University of Jerusalem’s Koret School of Veterinary Medicine in Israel.

“Dogs are affected by many of the same ocular diseases as humans, and their ocular anatomy and physiology are much more comparable to human eyes than those of the more commonly used pre-clinical research species, such as rabbits or rodents,” Sebbag said in a news release. “This makes dogs an especially valuable model in ophthalmic research.”
The Cleveland Clinic explains that hyaluronic acid exists as a naturally produced slippery substance in human bodies.
A Natural Boost from Hyaluronic Acid
Body tissues stay flexible and joints stay lubricated through the function of water while skin maintains stretchability and the body stays hydrated. The skin care industry uses glycerin as an active ingredient because it absorbs water to create the appearance of hydrated and plump skin.
The study team designed hyaluronic acid eyedrops with cefazolin and chloramphenicol antibiotic additives.
Ten dogs received the dropped preparation for eye testing which scientists evaluated against standard polyvinyl alcohol eyedrops.
More Absorption, Less Medication Needed
The research team discovered that dog eyes receiving hyaluronic acid drops absorbed cefazolin by 2.4 times greater and chloramphenicol by 4.2 times higher compared to standard polyvinyl alcohol drops.
Researchers reported that vets could possibly administer less antibiotic medicine in drug drops containing hyaluronic acid to treat eye infections since the higher drug concentration allows the drops to stay on the eye longer.
The execution of this method helps minimize antibiotic resistance according to their analysis.
According to the research team hyaluronic acid demonstrates additional favorable outcomes outside its role in medication transport, as reported by HealthDay.
Scientific studies demonstrated that hyaluronic acid displays antibacterial behavior along with wound healing acceleration, so it could benefit individuals with corneal scratches, according to researchers.
The substance enhances tear quality, thus making it a commonly prescribed remedy for dry eyes, according to the Cleveland Clinic.
Researchers plan to test the developed eye drops on dogs that have eye infections according to their statements.
