Osseäre Choristie
The osseous choristia is an eye disease in guinea pigs that is characterized by metaplastic bone formation in the eye . The cause of this guinea pig disease is unclear; congenital disorders or a vitamin C excess in the ciliary body are suspected . About 0.8% of guinea pigs show this disease.
In osseous choristia, bone tissue forms in the area of the middle skin of the eye . The tissue is visible as yellowish or whitish formations on the inside of the cornea , especially in the area of the corneal rim ( limbus corneae ). These formations can be spotted or circular and occur on both sides or only in one eye. The animal's well-being is mostly undisturbed. Treatment is neither necessary nor possible.
Complications in osseous choristia are obstruction of the aqueous humor outflow, which can lead to glaucoma (secondary glaucoma ), and corneal opacity.
