Helen Newlands’ 26-year-old gelding Ryan has struggled with a persistent eye concern for a while. Ryan, who was in any other case wholesome and acquired as a six-year-old for low-level eventing, first offered with a weeping and closed eye, and was discovered to have ulceration on the floor.
Helen instructed H&H Ryan began remedy underneath the Dick Vet Equine Hospital in Edinburgh, and for durations of time his eye would enhance, however the ulcers continued to return. After seeing an equine ophthalmologist Ryan was identified with immune mediated keratitis (IMK), and following a course of remedy he went into remission, however once more, the ulcers got here again.

“We noticed the ophthalmologist once more and it was advised we strive debriding the cornea, to virtually reset it. It appeared to assist, however then three months later he bought one other ulcer.”
Helen mentioned there have been conversations about eradicating Ryan’s eye, however in early 2021 vet Susie Armstrong sat down with human ophthalmologist Fraser Peck to assessment Ryan’s case. Focus was positioned on Ryan’s meibomian glands, which produce lipids that kind the floor lipid layer of the tear movie. When the tear movie turns into faulty, the floor of the attention can change into dry and the consequence could be ulceration.
A human remedy protocol for dry eyes was tailored for Ryan and he began the brand new regime in March 2021. This concerned every day sizzling compresses, and using a lubricant, serum and topical antibiotic.

“He was out 24/7 in the course of the summer season, and I can’t bear in mind the final time we had been in a position to do this as a result of we was once too nervous to go away him out in case he got here in with an ulcer,” she mentioned.
“I’ve had the identical yard proprietor, Pammy Stevens, for 20 years and with out her help I wouldn’t have gotten via all of it. It was emotionally draining, it was upsetting, and financially it was tough. His eye was solely insured for one yr so I’ve spent 1000’s over time, however this new regime is cheap.”
Helen mentioned Susie has been “so dedicated” to serving to Ryan, and this yr she nominated her within the Petplan Veterinary Awards.
“Susie first got here to see Ryan in 2016 as a locum, and she or he’s completely modified every part for us,” she mentioned.

We’ve all the time put eye points like these to mechanical issues for instance with their eyelid, or there was an underlying infectious part that continues to trigger these ulcers,” she mentioned.
“We’re now working in the direction of higher goal checks to help clinics and practices who perhaps don’t have all of the instruments they should make these diagnoses. We’re beginning to change the narrative to take a look at the tear movie when eyes, which we didn’t beforehand do.”
