Has this always happened? Is it just a few lashes or most on that side? Has the vet said (or can you tell) if the lashes are actually growing inward or if his lid is rolling inward?
If the lid is rolling inward and there’s been no injury to the eyelid, it makes me wonder if he might have a little dry eye on that side causing the lid to maybe not slide smoothly over the eye (maybe drag a little causing the lid to turn under). I’m just grasping at straws, but with what we’re going through with Moshi’s eyes right now and what all I’ve experienced with my own dry eyes, I thought it couldn’t hurt to throw this out there.
Our vet thinks Moshi’s eyes haven’t healed quickly because he doesn’t produce enough tears all the time. He started out on antibiotic drops and has been switched to antibiotic ointment. She said that GenTeal nighttime ointment for people is safe for bunnies and that it might be something we look at once Mosh’s eyes have healed. All it does is help lubricate the eyes and make them more comfortable. Anyway, it might be something to ask your vet about, if nothing else, might be worth asking if it would be an option to make Bobby’s eye more comfortable until he gets in to see the vet when his eyelashes do turn in.
