Progressive retinal atrophy (PRA) is a group of genetic diseases seen in certain breeds of dogs and, more rarely, cats. Similar to retinitis pigmentosa in humans, [ 1 ] it is characterized by the bilateral degeneration of the retina , causing progressive vision loss culminating in blindness.
Symptoms include sudden permanent blindness, but may occur more slowly over several days, weeks or months, [3] dilated pupils. Pupillary light reflexes are usually reduced but present; the slow phase mediated by melanopsin in retinal ganglion cells is retained.
Older dogs, similar to this 10-year-old Neapolitan Mastiff, often grow grey hairs on their muzzles, and some dogs grow grey hair all over. Not all dogs gain grey hair when aging. Aging in dogs varies from breed to breed, and affects the dog's health and physical ability. As with humans, advanced years often bring changes in a dog's ability to ...
Symptoms include sudden permanent blindness, dilated pupils, and loss of the pupillary light reflex. [63] Retinal detachment* is caused in dogs by genetic disorders such as retinal dysplasia or Collie eye anomaly, trauma, inflammation or cancer. Reattachment may occur spontaneously or with medical or surgical therapy.

Cataracts typically occur when proteins break down in the lens of a dog's eye and clump together, obstructing the passage of light. [1] [2] There are several reasons cataracts may occur in dogs, such as heredity, trauma, aging, diabetes, glaucoma, and progressive retinal atrophy.
Retinal detachment occurs with complete retinal dysplasia, and is accompanied by blindness in that eye. Cataracts or glaucoma can also occur secondary to retinal dysplasia. Other causes of retinal dysplasia in dogs include infection with canine adenovirus or canine herpesvirus , or radiation of the eye in newborns.
Depending on the grade, your dog’s symptoms, and the results of x-rays, your vet will advise whether the luxating patella needs treating. Luxating patella treatment involves surgery, which is ...
