You could get some saline solution from your grocery store, normal contact lens solution should work. And then drop some in his eye to wash it out and see if that works. The saline solution is very safe, and won’t cause any problems if it is something other than just a floaty.

Well if you use the Saline Solution make sure it’s a new unused bottle so it’s not contaminated. Some of my rabbits have had this gunk stuff in their eyes and eventually it “rinses” out on it’s own. Good to know you have an appt with a vet for him soon too.

It is also recommended not to use the solution again for yourself or someone else if you rinse the eye. You could transmit bacteria to your own eye by accident.

My bunny recently is having similar problem but it starting to clear up and I have been using just water.  I soak a paper towel in water and at the corner of her eye I squease it and open her eye just a bit and have the water wash it out.  I have to do that a couple of times, and whatever was in her eye irritated her tear duct so she was getting crusties.  I would just use a paper towel soaked in water as a compress to moisten the crusties and then comb it out.  Her crusties came back about every other day but it was noticably better when I washed hereye out twice a day and so far it’s been pretty clear, and I did extra litter box changing and sanitized the cage just incase.

My buns get occasional eye cruddies too sometimes that seem to work themselves out, but you may actually be seeing the third eyelid popping out. Rabbits and many other mammals have an extra, thin, pale white/semi-translucent membrane to help protect the eye, and sometimes it can either relax out of its spot or be temporarily paralyzed, covering a decent part of the eye. If it is the membrane sticking out in your bun (the fact that you described it as “skin” is what got me thinking this), the fact that it disappeared on you and went back to normal would lead me to believe that the bun’s just tired But it’s always worth mentioning to the vet in case it turns out to be something else- he may well have had something stuck there too. I would also make note, if it comes out again, if it’s in one eye or both, and mention that to the vet too. I wouldn’t go nuts messing with it beforehand though if the bun doesn’t appear to be bothered- bugging their eyes too much can create more problems.

Pictures of a normal and and abnormal third eyelid are here: http://www.medirabbit.com/EN/Eye_diseases/Differential/Nictitating.htm (there are lots of scary things listed on that page but in those cases, you would have a rabbit in serious distress and the eyelid would probably be the last thing you noticed! Your description sounds very much like the normal picture on the left.)

As long as it’s not itchy, painful, inflamed etc, and his face is symmetrical (no droopy eyes or way more membrane in one eye than the other), I wouldn’t worry much. A non-irritated small change in an eye in an otherwise happy healthy bunny shouldn’t require a rush to the ER But it should be checked out soonish just in case. Good luck!

(Also as a random FYI, problems with the third eyelid are usually due to damage to the nerve, not tear ducts)

Ah yes definitely not something built in if it’s floating to the middle of his eye Hopefully it’s nothing major then! Both my buns (and the last one too) get miscellaneous cruddies like that from time to time and they never seem to do anything, just work their way out after a day. Mine also don’t mind if I wipe them off as I’m petting them. Hopefully it’s no big deal Good luck!
