Ocular Disease in Papillons

Three signs together indicate ocular pain: squinting or holding the lid partly closed, excessive watering, and rubbing or pawing at the face. Add redness and you have a dog that needs an appointment the same day.

A corneal ulcer is the commonest cause. The cornea is the clear front surface, and a scratch from a twig, a rough play session or a grass seed breaks its protective outer layer. Ulcers are painful, they can deepen quickly, and a deep one can perforate. They are usually straightforward to treat when caught early and much less so when they are not.

Glaucoma is the emergency that owners have generally never heard of. Fluid produced inside the eye cannot drain properly, pressure climbs, and the optic nerve is damaged by that pressure. Vision can be lost permanently within a day or two if the pressure is not brought down. The eye may look red, the pupil may be dilated and unresponsive, the surface may go cloudy, and the dog is usually in considerable pain, often shown as lethargy or withdrawal rather than as vocalisation.

Because an ulcer and glaucoma look superficially similar and are treated very differently, and because some treatments for one are harmful in the other, this is not a situation for leftover drops from a previous episode. Never put any medication into a painful eye without a vet examining it first.

Screening is the reason inherited blindness is less common than it used to be. It is only useful if you know what you are being shown.

If you think your Papillon has ocular disease, 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 patellar luxation, progressive retinal atrophy, dental disease.

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 ocular disease it is often what separates a clear pattern from a guess.
