The strangest damn thing

I recently saw a woman in her late sixties who presented to the ER with severe shortness of breath. She had a history of COPD, or emphysema, due to a long history of smoking. She also had a history of Grave's disease, a thyroid disorder, which had left her with a mild residual proptosis. What happens in this condition is that for some reason there is accumulation of this gelatinous goo in the orbit, behind the eyeball, causing the eye to be displaced forward. Put simply, she looked a bit bug-eyed.

It was her breathing, though, that had captured my attention. She was not moving air well, and was becoming progressively more sleepy -- a bad sign. A blood gas confirmed that she was retaining carbon dioxide, and at this point it was clear that she was going to need some ventilatory support. In the "old days" I would have intubated her, but lately we've been trying to avoid that with what's called "non-invasive mechanical ventilation," or NIMV. What we do here is strap a mask to the patient's face to create a good seal, and attach it to a machine which blows a little extra air into the lungs every time the patient tries to take a breath. We hooked her up, and she seemed to perk up a bit, and I wandered off to make arrangements for her to go to the ICU.

Moments later, a panicked respiratory tech was grabbing me: "Come quickly! Now! Now! Her eye fell out!"
What can you say to a statement like that? I ran to the bedside, and sure enough, something like this is what I saw:Although it was only her right eye that was out, and it was a bit further than in the picture above. It was actually drooping or dangling just a little bit, due to gravity. Oh yeah, and she was screaming bloody murder and clawing at the face mask. We removed the face mask, and stood there in complete and utter shock. Not really having any clue of what to do, I put on some gloves and gently massaged the globe back into the orbit. Once in, she felt better (no kidding!) and her vision seemed intact.

I figure that the face mask must have been putting some pressure on the nasal surface of the eye socket, and the strap, which has to be cinched pretty tightly, was putting pressure on the temporal aspect of the socket, and with the globe perched a little forward to begin with, it just got squeezed out like a zit!

Needless to say, we did not put her back on NIMV. I let the ICU doc know why she was not on NIMV, and suggested he might want to get an opthalmology consult, and sent her on up.

That was the strangest damn thing I have seen in a long time...

Any coders out there? Is there a CPT code for "manual reduction of prolapsed globe?" I bet there is; there's a CPT for everything. How many RVU's for that one?

I have the greatest job in the world.

WTF?!?! BiPAP can cause your eyes to pop out?!?! Seriously, I can't wait to see that one for myself!!!

Yaargh. I hate eyeballs - I am impressed by your professionalism! I would have stood there going, "Yaargh, her eyeball fell out!"

Which is why I'm only a second year. Maybe they teach you how to control that particular urge in third year.

GREAT story.

Well, I just wonder why you didn't switch to a nasal pillow mask, which would provide the BiPAP therapy without the pressure on the eye socket. But then, I'm just a lay person, so what the heck do I know?

Here's an example. The hose does not necessarily have to go over the head if you choose a different mask. There are many, many different styles that would avoid the eye socket pressure.

Eye can't believe it. What an eye opening experience that must have been. Eye don't know what the CPT code would be either.

Prior to medical school, when I was in practice as a veterinarian, it was not at all uncommon for certain breeds of dogs to present with one or occassionally both eyes dangling from the optic nerve like little tether balls.

This would occur with the brachecephalic breeds (the ones with the short flat faces that look like they must have run into a wall at high speed...such as pugs, schitzus, etc), also known in some circles as the "puntable breeds."

As part of their bizarre anatomy, they tend to have a fairly poorly formed bony eye socket and it is thus fairly easy for an eyeball to pop out if there is enough pressure.

Often this would occur from something as simple as the dog getting overly excited and barking too forcefully.

I always wondered what must be going through the dogs mind when this occurs. There you are giving some cat a hard time when suddenly your damn eyeball pops out. Talk about a bad case of double vision.

And to make matters worse, now that damn cat thinks your eyeball is some sort of toy for it to attack.

Life must be hard if you're a flat faced dog!

I'll have to add that to the informed consent spiel: "Claustrophobia, pneumothorax, eyeball falling out..."

Gee... and I thought being nearsighted was bad!

Wow, he sure looks surprised that his eyes are that big.

I am bronzing this post and hanging it from my rear view mirror. I don't remember the last time my jaw actually dropped while reading a blog. Nicely done!

Dear God! I admire your aplomb, I personally would have fainted dead away at the side of the patients bed!

That was awesome!

Dude, I'm printing this and passing it around the Respiratory Therapy department. This is the first time I've ever heard of BiPAP making a patient's eye fall out!

teresa: because nasal pillows are a finicky seal and if the patient is CO2-narcosed and half-comatose their mouth hangs open -- all the pressure of the BiPAP then escapes out their mouth. It also blows boogers everywhere.

*shudders*

Eye injuries are number 2 on the list of injuries that gross me out...

Rogue Medic said...

Chest PT must be equally entertaining on this patient.

Good points. Thanks for the counter view.

I swear, the very same picture is in my emt book! Yay, eyeballs...that end up okay, that is.

I have set up thousands of cpap/bipap patients and I think I know what happened. In some patients, the duct in the nose connecting to the eye is enlarged. I have seen "fluttering" eyelids when cpap was applied by either a nasal or full face mask. I suspect you had something like this happen.

SOLUTION: The Respironics TOTAL-FACE mask that covers the eyes, note, mouth, so that all pressure is equal.
