I don't know if it's the same thing, but several years ago I had an ameraucana chick hatch with both eyes bulging. It could not see and I had no idea what to do with it. Eventually, one of the eyes ruptured and receded, but the other one still had a bulge and she did ok, even though she was blind. A veterinary student adopted her & they took her to the vet school and removed the eye that was still bulging for pathology. Turned out she had glaucoma - I had no idea chickens ever got glaucoma & I've never seen it since, but probably a good idea to have the eye examined by a vet to see if there is pressure behind the eye causing pain.
