It is one of the diseases of unknown origin that affects the corneal surface of the eyes in cats of any breed.
It is also known as proliferative keratoconjunctivitis, this because it manifests itself with a proliferation of cells on the cornea in the form of membranous growth from the outer edge towards the center.
Generally, the presentation is unilateral, but invariably evolves to bilateral. If early treatment is not applied, it can also continue to gradually invade the annexes of the eyes.
There are many cats, especially those that lead or led life in the outdoors, who are in apparent good health but are in fact carriers of feline herpes virus. This virus is considered a predisposing factor of this disease. Treatment may not be complicated under a correct diagnosis.
