title: Prevalence of uveal cysts and pigmentary uveitis in Golden Retrievers in three Midwestern states.
abstract: OBJECTIVE
  To determine the prevalence of uveal cysts and pigmentary uveitis (PU) in Golden Retrievers in 3 Midwestern states.
  
  
  METHODS
  Prospective cross-sectional study.
  
  
  METHODS
  164 American Kennel Club-registered Golden Retrievers in the states of Illinois, Indiana, and Michigan.
  
  
  METHODS
  For all dogs, biomicroscopic and binocular indirect ophthalmoscopic examinations of both eyes were performed after pupillary dilation. A finding of pigment deposition in a radial pattern or in zones on the anterior aspect of the lens capsule of 1 or both eyes was required for a diagnosis of PU.
  
  
  RESULTS
  Eighty of the 328 (24.4%) eyes and 57 of the 164 (34.8%) dogs had visible uveal cysts. Of those 80 eyes with cysts, 41 (51.3%) had a single cyst located nasally and posterior to the iris, 33 (41.3%) had multiple uveal cysts, and 6 (75%) had a single, free-floating cyst. A diagnosis of PU was made for 9 (5.5%) dogs.
  
  
  CONCLUSIONS
  Prevalences of uveal cysts (34.3%) and PU (5.5%) in the examined Golden Retrievers were both higher than prevalences reported previously (5.4% for uveal cysts and 1.5% for PU) in the Canine Eye Registry Foundation's 2009 All-Breeds Report. Study findings have indicated that PU is not a rare condition and should be considered as a differential diagnosis for Golden Retrievers with ocular disease.
