Case Study 11


Iris cysts occur less commonly in cats than in dogs however, in cats, they are more likely to cause problems that require treatment. The cysts are often multiple, thick-walled and remain attached to the posterior surface of the iris. This results in forward displacement of the iris with compression of the iridocorneal angle and secondary glaucoma. Fortunately, treatment using the diode laser is highly successful. The photo below illustrates the eye immediately post laser treatment with remnants of the cyst present within the anterior chamber. A video illustrating treatment of iris cysts is seen at the bottom of this page.
