Common Causes Of Blindness In Dogs


There are many causes of vision loss in dogs; some are born blind as a result of a congenital disorder, while there are those that become blind as a result of illness or injury. Certain breeds of dogs are more predisposed to hereditary conditions or acquired diseases that can affect their sense of sight. However, any dog can develop vision problems. For some, vision loss may be an age-related condition; in fact, blindness is a common problem among senior dogs. Here are some of the most common conditions that are known to cause blindness in dogs:


Affected dogs develop cloudiness in the lens of the eye. Diabetes is a common predisposing factor.


There is an increased pressure inside the affected eye causing pain and discomfort. Diabetes that is not well-regulated can predispose glaucoma in dogs.

Progressive Retinal Atrophy (PRA)

PRA is a heredity condition characterized by the degeneration of the retina. There is no cure available for PRA.
Other causes include retinal detachment, brain disease, trauma, macular degeneration, corneal ulcers, and Sudden Acquire Retinal Degeneration Syndrome (SARDS). Any eye problem should be brought to the attention of your Flushing, NY veterinarian. Learn more here.
