PRA diagnosis costs $200-$500, and there is no treatment or cure. Progressive retinal atrophy is an inherited eye disease that gradually destroys the retina, leading to complete blindness. It's painless and dogs adapt remarkably well, but there's nothing veterinary medicine can do to stop or reverse it once it begins.

What Is Progressive Retinal Atrophy

PRA is an inherited eye disease where photoreceptor cells deteriorate over time. Rod cells (night vision) are affected first, then cone cells (day vision). It comes from genetic mutations passed down from the parent dogs. Affects dozens of breeds with different variants

Symptoms

What to Watch For

Night blindness is the first sign - bumping into things in dim light, avoiding dark rooms and stairs. Eyes may develop reflective shine or dilated pupils. Gradual loss of daytime vision. Cataracts often develop secondary to PRA. Progression is slow and painless

Diagnosis

$200-$500

Veterinary ophthalmologist exam ($150-$300) examines the retina for characteristic changes. Electroretinography (ERG, $200-$400) measures retinal function and detects PRA before clinical signs. DNA testing ($50-$200) identifies carriers and affected dogs. Average $200-$500

Treatment

No Cure Available

No treatment, medication, or surgery can stop or reverse PRA. Antioxidant supplements ($20-$50/month) may theoretically slow progression, but evidence is limited. Management focuses on helping your dog adapt - keeping furniture in place, using verbal cues, maintaining routines. Management costs $200-$500

Total Cost

$200-$500

Primarily diagnosis costs. Ongoing expenses are minimal since there's no treatment. $200-$500 for diagnosis and initial management.

Certain Breeds

Higher Risk

Labradors, Cocker Spaniels, Miniature Schnauzers, and Irish Setters are commonly affected. DNA testing before breeding is essential for at-risk breeds.

Timeline

Months to Years

Progression varies by PRA type. Some forms cause blindness within months; others take 1-3 years. Most dogs are fully blind by middle age.

Prevention

DNA testing of breeding dogs is the only prevention. Responsible breeders test for PRA before breeding. Ask for genetic test results when buying a puppy.

Insurance Traps

PRA is inherited - and that's exactly where insurance gets complicated.

Hereditary Condition Coverage

Coverage

PRA is genetic/hereditary. Many policies cover hereditary conditions; some exclude them. Check your policy's stance on hereditary and congenital conditions before enrolling. Policies covering hereditary conditions typically cover diagnosis.

The Pre-Existing Problem

Pre-existing

Any vision problems before you enroll get PRA classified as pre-existing and excluded. Since PRA develops gradually, early enrollment is critical. DNA test results showing carrier status may also affect coverage.

Limited Financial Impact

Exclusion

Since PRA has no treatment, insurance payout is limited to diagnostic costs ($200-$500). Real value comes from covering secondary conditions like cataracts that develop alongside PRA.

Breed-Specific Considerations

Exclusion

Some insurers charge higher premiums or add exclusions for breeds with high PRA rates. Labrador Retrievers and Cocker Spaniels face closer scrutiny. Disclose breed info honestly - false claims void policies.

Common Questions

Real answers about costs, treatment, and insurance coverage.

What are the first signs of PRA in dogs?

Night blindness is almost always first - bumping into things in dim light, avoiding stairs at night. Eyes appear more reflective (greenish shine). Early signs are subtle and easy to miss until daytime vision declines too.

Can progressive retinal atrophy be treated?

No - no treatment, medication, or surgery can stop PRA. Gene therapy research shows promise but isn't clinically available. Some vets recommend antioxidant supplements, though evidence is limited. Focus on helping your dog adapt to vision loss.

How fast does PRA progress?

Depends on genetic form - some cause noticeable vision loss in months, others over 1-3 years. Most dogs are completely blind by middle age. Early-onset forms progress faster than late-onset. An ophthalmologist can estimate the timeline.

Can dogs with PRA still have a good quality of life?

Yes. Blind dogs adapt well - they navigate by smell and hearing. Keep furniture in the same places, use textured rugs as landmarks, maintain routines. PRA is painless. Most owners report happy, active blind dogs.

How is PRA diagnosed?

An ophthalmologist examines the retina via ophthalmoscope for thinning blood vessels and reflective tapetum changes. ERG measures retinal electrical activity and detects PRA before clinical signs. DNA tests identify breed-specific mutations. Total: $200-$500.

Is PRA painful for dogs?

No - PRA is completely painless. Secondary cataracts can develop in PRA eyes, and rarely those cause inflammation (lens-induced uveitis), which is painful. Regular eye checkups catch secondary complications early.

Can PRA be prevented?

Responsible breeding is the only prevention. Reputable breeders DNA-test before breeding - if both parents are clear, puppies won't develop that PRA form. Ask for genetic testing certificates when buying from at-risk breeds.

Does pet insurance cover PRA?

Depends on hereditary condition coverage - many comprehensive policies do cover PRA diagnosis. Since there's no treatment, payout is limited to diagnostic costs ($200-$500). Secondary cataracts requiring surgery may also be covered. Enroll before any vision symptoms show up.

Then came the shock. August 2026, I'm sitting on a bench outside a veterinary clinic in Brno. After his first epileptic seizure. Alf, healthy until recently, has just been diagnosed with a tumor in his belly and one in his head. I look at my own realvetcost.com, and it's one of the three most common conditions in Boxers.

I don't want to see the prognosis, but it's clear. How did it end?
