Uveal Cysts

Uveal cysts (sometimes also referred to as “iris cysts”) may arise from the posterior iridal or ciliary body epithelium as a result of hereditary factors, cystic hyperplasia and/or chronic inflammation. Clinically, uveal cysts comprise oval to round, thin-walled, translucent to dark brown structures which may be attached to the ciliary tissue, float freely within the anterior or posterior chambers (or rarely within degenerate vitreous) and/or rupture and adherer against intracameral surfaces including the lens capsule and/or corneal endothelium. Uveal cysts may occur unilaterally or bilaterally and may vary significantly in both size and number. Commonly affected breeds include the Labrador Retriever, Golden Retriever, Boston Terrier, Great Dane & American Bulldog.
