Corneal Staining with Fluorescein

CHAPTER 1

Hello, my name is Alexander Martin, doctor of Optometry at Boston Vision. I'm about to perform corneal staining.

CHAPTER 2

Okay, this procedure we're doing is putting fluorescein in the eye. Anytime that a patient presents with potential abrasions, scratch, something that could be in the eye, metal foreign body, anything, we want to make sure that we catch every little piece of it. Just look up. And all you need is one little touch. That's all you really need. You don't need to... I've seen students paint the whole eyeball with this stuff. You don't need that.

CHAPTER 3

Just a little bit. The key with this is that when you're looking with blue light... Is that anything that's eroded will shine a nice, bright green. Look all the way up. Look down. If you're looking for foreign bodies, a lot of times you're looking for a tracking pattern if you can't necessarily find what it is you're looking for. And then look up again. And then straight ahead. And in this case, the patient actually looks pretty good. I don't see any tracking patterns. Look down. No focal erosions on the cornea, which are called SPK, superficial punctate keratitis. All we're seeing is just a little bit of dryness and evaporation.
