What are some causes of dog blindness?

Blindness in dogs can be caused by various conditions such as glaucoma, cataracts, thickening of the lens known as nucleus sclerosis, a rare condition called SARS where the retina is attacked by the immune system, or high blood pressure.

Severe corneal disease caused by dry eye or chronic keratitis, dense cataracts, and retinal detachment are some causes of dog blindness. If you suspect vision loss, take your dog to a vet as it could be due to age-related changes. Eyesight cannot be maintained just by applying substances to the eyes, as vision loss is usually due to a biological process.
