Dog Pannus and Pigmentary Keratitis Management

Pannus (chronic superficial keratitis) is a progressive immune-mediated eye condition in dogs that requires lifelong treatment to preserve vision.

Key Facts

Pannus (chronic superficial keratitis) is an immune-mediated corneal disease most common in German Shepherd Dogs
UV radiation exacerbates pannus - dogs at high altitude or with significant sun exposure have more severe disease
Characteristic pink vascular tissue progressively covers the cornea, leading to vision impairment if untreated
Topical cyclosporine and tacrolimus suppress the immune response and halt progression in most cases
Treatment must be lifelong - discontinuing medication causes rapid return of disease activity
Protective eyewear (doggles) reduces UV exposure and can meaningfully slow progression in affected dogs
Regular monitoring by a veterinary ophthalmologist allows medication adjustments based on disease activity

Welfare Considerations

Progressive corneal pigmentation from untreated pannus causes visual impairment and eventually blindness. The immune-mediated inflammation is also uncomfortable. Dogs at altitude or in sunny environments have more severe disease - lifelong topical immunosuppression is the key to preventing the vision loss that causes lasting welfare harm.

What You Can Do

Seek veterinary ophthalmology evaluation for any German Shepherd with visible eye changes or vision problems
Begin topical cyclosporine or tacrolimus as prescribed and administer consistently
Consider UV-protective doggles for German Shepherds in high-altitude or high-UV environments
Schedule ophthalmology rechecks every 3-6 months to monitor disease activity
Inform rescue organizations and breed clubs about pannus risk in German Shepherd Dogs to improve early detection
