Iridociliary Cysts in Dogs
Sometimes referred to as iris cysts or uveal cysts, iridociliary cysts are often benign and require no treatment. However, occasionally they may be large enough to interfere with vision or with the function of the eye.
Symptoms and Types
Iridiociliary cysts may be attached to various parts of the interior of the eye. They may be lightly or darkly pigmented and are semitransparent. They may be spherical to ovoid in shape. They can vary considerably in size and there may be more than one. They may be seen in one or both eyes.
In most cases, these cysts are an incidental finding. Only when they are large enough to impair vision or interfere with the normal functioning of the eye are they problematic. Glaucoma can be a complication associated with iridociliary cysts.
Cysts may be congenital or acquired.
There is a breed predilection in Boston terriers, golden retrievers and Labrador retrievers for iridociliary cysts. In golden retrievers, a syndrome of pigmentary uveitis and iridociliary cysts is seen. These cysts have also been associated with glaucoma in golden retrievers and in Great Danes.
Iridociliary cysts are diagnosed with an ocular examination.
In most cases, no treatment is necessary. If uveitis or glaucoma is present, these diseases will need to be treated appropriately. Laser coagulation can be used to remove particularly large cysts if necessary.
