Plain-English summary
A group of 404 dogs in France was diagnosed with cataracts, with the average age being 9 years old. The most common causes of cataracts included breed predisposition, especially in Yorkshire Terriers, aging, and progressive retinal atrophy. Other factors like diabetes and trauma were also noted, but in some cases, the cause was unknown. If your dog is showing signs of vision problems, it's important to consult your veterinarian for a thorough eye examination and potential treatment options.

Abstract
OBJECTIVE: To determine the epidemiology and the clinical presentation of cataracts in a population of dogs in France. PROCEDURES: Records of dogs affected by a cataract presented at the Ophthalmology Unit of Alfort Veterinary School during 2009-2012 were reviewed. The etiology was determined for each dog. The signalment of affected dogs, their medical history, age of onset, stage of progression, location of opacities, and ocular lesions associated were evaluated for each etiology. RESULTS: A total of 2739 dogs were presented at the Ophthalmology Unit from 2009 to 2012. Four hundred and four dogs (14.7%) (716 eyes) were diagnosed with a cataract. The population included 218 males (54%) and 185 females (46%). The gender was not recorded for one dog. The mean age (±SD) of all dogs affected by a cataract was 9 years (±3.9 years). Fifty-four breeds were represented. The Yorkshire Terrier was the only breed significantly overrepresented. The causes of cataracts observed were breed predisposition (28%), aging (22.8%), progressive retinal atrophy (12.4%), congenital cataract (5%), diabetes mellitus (4.7%), trauma (3.7%), uveitis (3%), and hypocalcemia (0.2%). In 20.3% of the cases, the etiology could not be determined. Ocular lesions associated with cataracts reported were lens luxation or subluxation (11.1%), glaucoma (3.7%), and retinal detachment (4.2%). CONCLUSIONS: In a French population of referred dogs, 14.7% were affected by a cataract. The main causes identified were breed predisposition, aging, and progressive retinal atrophy. A breed predisposition for the Yorkshire Terrier was recorded.
