Pseudopterygium
Pseudopterygium (also "pseudo-wing skin " or precorneal membranous corneal occlusion , see also: Pterygium ) is a malformation of the conjunctiva that occurs mainly in domestic rabbits . The malformation is probably inherited .
In Pseudopterygium, a grayish fold of the conjunctiva, which consists of connective tissue and fine blood vessels , extends far over the cornea to close to the edge of the pupil . In contrast to the pterygium conjunctivae in humans, however, there is no adhesion with the cornea, so the pseudopterygium can easily be lifted off the corneal surface.
The treatment is carried out surgically by removing the excess conjunctival fold and subsequent treatment with an eye ointment containing cortisone . A relapse is possible.
