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.
One such condition is progressive retinal atrophy, or PRA, which affects the light-sensitive cells at the back of the eye. It affects over 100 breeds, can be caused by multiple different genetic ...
Sudden acquired retinal degeneration syndrome (SARDS) is a disease in dogs causing sudden blindness. It can occur in any breed, but female dogs may be predisposed. [ 1 ] Approximately 4000 cases are seen in the United States annually.
Retinal diseases Progressive retinal atrophy (PRA) is a genetic disease of the retina that occurs bilaterally and is seen in certain breeds of dogs. It causes progressive vision loss culminating in blindness. [63] Retinal dysplasia is an eye disease affecting the retina. It is usually a nonprogressive disease and can be caused by viral ...
The most common sign of CEA is the presence of an area of undeveloped choroid (appearing as a pale spot) lateral to the optic disc. The choroid is a collection of blood vessels supplying the retina. CEA can also cause retinal or scleral coloboma, coloboma of the optic disc, retinal detachment, or intraocular hemorrhage.
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 .

Progressive Retinal Atrophy (PRA) is a set of genetic eye diseases that frequently occur in Australian Cobberdogs and can lead to blindness. The nerve cells at the back of the eye break down over time and will cause cataracts to form. PRA frequently initially manifests as night blindness; this can progress to total blindness.
