Staining eyes in general practice

Why should all veterinarians be informed about ocular surface staining? Applying diagnostic dyes to a patient’s eyes can help assess their condition and determine an injury or disease in need of treatment.

In a dvm360 interview recorded at the 2025 Fetch dvm360 Conference in Kansas City, Missouri, Shelby Bossler, DVM, discusses the prevalence of corneal ulcers, dry eye and other ocular conditions general practitioners typically see. Bossler is a technical services veterinarian with Dômes Pharma, developer of premade fluorescein drops (Fluodrop) for ophthalmologic exams.

The following is an edited transcript of the video:

Shelby Bossler, DVM: Corneal ulcers are very common in general practice. It kind of does depend on what area of the country you live in. I feel like I've heard other [general practitioner] veterinarians from the southeast say they see ulcers all day, every day. They definitely have one [or] maybe a handful a week, and they seem to be worse than in other geographies.

I practice sometimes in Ohio, and we don't see a severe of ulcers, but it is something that every general practitioner will see at some point. We see dry eye disease. We have all kinds of issues where we're going to be staining the eyes pretty frequently. Also, if you have any emergency cases traumas, you're going to be staining the eyes too. And as general practitioners, we see that, for sure. Ophthalmologists stain every single eye pretty much that comes into their practice. So they do a complete ophthalmic exam. That's their specialty. So they are doing all of the tests, including staining and with ulcers. I mean, we all see them, but ophthalmologists are going to see them probably more frequently than us general practitioners.

A lot of us can manage them and are comfortable managing them. A lot of veterinarians didn't have a lot of ophthalmology training, and a lot do get referred. So one thing that we are really passionate about at Dômes Pharmais education. We have a lot of resources available, staining guides, we have some treatment guides. We try to get [continuing education] out there with ophthalmologists to try to make it more accessible and really help general practitioners feel more confident.
