Bichon Frise Cataracts: Cloudy Eyes, Real Vision Loss and What Can Be Done

Almost every dog over about eight develops a faint bluish-grey haze in the centre of the eye. It is caused by the lens fibres compacting with age, and it is not a cataract. Vision is largely preserved, no treatment is needed, and it progresses so slowly that most dogs never notice.

A cataract is different. It is an actual opacity, and it looks white or pearly rather than blue-grey. Shine a light into the eye from an angle and an age-related haze still lets you see a reflection from the back of the eye; a dense cataract blocks it.

That said, this is not a distinction to make finally at home. The reason to attempt it is to know how urgently to book, not to avoid booking.

The practical difference for an owner is behaviour. A dog with age-related lens hardening walks into nothing. A dog developing cataracts starts hesitating in dim light, missing a thrown toy it used to catch, bumping furniture that has been moved, or becoming reluctant on stairs at night.

In a breed where cataracts are documented, any of those behavioural changes deserves an examination rather than a wait.

Owners often assume the worst outcome of a cataract is blindness, and that a dog that copes well needs nothing. There is more to it than that, and these are the reasons a vet wants to see the eye rather than record it.

If you think your Bichon has cataracts, the plan is three steps: write down what you have seen and when it started, book a veterinary appointment rather than waiting for the next flare, and take video of the behaviour or symptom before you go — the thing you are worried about rarely happens in the consulting room. Screening in the parents covers skin allergies, patellar luxation, bladder stones.

What the vet visit should produce is a diagnosis and a written plan, not just reassurance: what is being ruled out, what the monitoring interval is, and which signs mean you come back sooner. Ask what the treatment costs across a year rather than per visit, because that is the number that decides whether you are managing this condition or reacting to it.

Between appointments, keep a short log — dates, what you saw, what changed. It is the single most useful thing an owner brings to a follow-up, and for cataracts it is often what separates a clear pattern from a guess.
