Like humans, many dogs develop eye problems later in life. But there are also diseases and other risk factors that can cause trouble.
Cataracts are the most common cause of sight issues and blindness. It’s easy to spot because the eye looks cloudy. Cataracts dim the lens of the eye, blocking light from reaching the back.
It’s common in old age, but it can also be triggered by diabetes. Breeds that have a higher genetic risk for developing diabetes include cocker spaniels and poodles.
Glaucoma that occurs when fluid pressure builds up inside the eye, damaging the optic nerve, is common too. Dogs with a genetic risk for this include great Danes, bassets and chow chows. It’s recommended they have frequent eye exams.
The genetic disease Progressive Retinal Atrophy (PRA) attacks the retina, causing it to wither. Dogs with a genetic risk for this include labradors, retrievers and border collies.
Finally, there the mysterious Sudden Acquired Retinal Degeneration Syndrome (SARDS) that attacks mostly middle-aged female dogs, particularly Dachshunds and Schnauzers. It’s uncertain what it is, but dogs that get this lose their sight within days or weeks.
As some of these conditions can be managed or slowed down with good vet care, making an eye exam a regular feature is a sensible step towards protecting your pet.
