Pannus in Dogs: Managing Chronic Eye Inflammation

Chronic superficial keratitis (pannus) is an immune-mediated eye condition requiring lifelong management to prevent vision loss in affected dogs.

Key Facts

Pannus predominantly affects German Shepherd Dogs, Belgian Malinois, and Greyhounds
UV light exposure worsens the condition - it is more severe at higher altitudes
The condition involves progressive pigmented vascularization of the cornea from the limbus inward
Untreated pannus causes progressive corneal opacification and blindness
Treatment with topical corticosteroids and tacrolimus controls inflammation effectively
Cyclosporine eye drops are an alternative first-line treatment
Lifelong treatment is required - stopping medication causes relapse within weeks

Welfare Considerations

Pannus progresses silently - the dog adapts to gradual vision loss and owners may not notice until significant damage has occurred. Without treatment, affected dogs eventually become blind in both eyes. Lifetime topical treatment maintains clear vision and prevents this avoidable welfare outcome. UV-blocking dog goggles during outdoor activity supplement medication by reducing the primary trigger. Regular ophthalmological monitoring ensures treatment adequacy before irreversible opacification develops.

What You Can Do

Begin topical treatment immediately on diagnosis - delay allows permanent corneal damage
Administer eye drops consistently - twice daily application is typically required lifelong
Use UV-protective dog goggles during outdoor activity, especially at high altitude or in snow
Schedule 6-monthly ophthalmological rechecks to monitor treatment adequacy
Never discontinue treatment without veterinary guidance - relapse occurs rapidly
