Brachycephalic dog breeds are popular around the world, yet many brachycephalic dogs are affected by numerous health problems, including several head related diseases that are directly linked to their conformation. In addition to the well-recognized disorders associated with the respiratory system (brachycephalic obstructive airway syndrome, i.e., BOAS), brachycephalic dogs have a concerningly high prevalence of ocular surface disorders that can cause chronic discomfort, loss of the globe, and/or require long-term, daily therapy.
Brachycephalic ocular syndrome (BOS) is described as bilateral ocular changes associated with poor skull conformation, of which some or all abnormalities are associated with brachycephaly in dog breeds.
These breeds include Bulldogs, Pugs, Boston Terriers, Pekingese etc, and have a shortened skull and nose resulting in a flattened looking face.
Abnormalities include a shallow orbit in conjunction with euryblepharon leading to ‘scleral show’, entropion, trichiasis, exotropia, lagophthalmos, reduced corneal sensation and compromised tear film.
Early recognition of these issues are advised, particularly around the time of vaccinations at your primary vet and each year we would recommend a review of your pets eyes at the same time.
