Uveal cysts in dogs: 28 cases (1989-1991).

In a 3-year retrospective study, 28 dogs were determined to have uveal cysts arising from either the ciliary body or the iris or free-floating in the anterior chamber. Golden Retrievers, Labrador Retrievers, and Boston Terriers were represented more than other breeds. Mean age of cyst development was 7.0 years in Golden Retrievers, 9.1 years in Labrador Retrievers, and 6.8 years in Boston Terriers. There was no sex predilection in any breed. Evidence of associated ocular lesions, other than visual impairment in 1 Boston Terrier, was not noticed.
