Dog Pannus: Chronic Eye Condition Welfare Management

Pannus is a progressive inflammatory eye condition causing corneal opacity and vision loss in dogs. Lifelong treatment maintains vision and prevents significant suffering.

Key Facts

Pannus (chronic superficial keratitis) is an immune-mediated condition affecting the cornea
German Shepherd Dogs and their crosses are most commonly affected, with a breed predisposition
UV radiation exacerbates pannus, making altitude and geographic location significant risk factors
Clinical signs include corneal pigmentation, vascularization, and progressive opacity
Without treatment, pannus causes significant vision impairment and chronic corneal discomfort
Treatment with topical corticosteroids and cyclosporine is highly effective but must continue lifelong

Welfare Considerations

Untreated pannus causes progressive loss of vision alongside chronic ocular discomfort. The condition is manageable but not curable, making owner compliance with lifelong treatment the critical welfare variable. Dogs whose owners discontinue treatment experience deterioration that may not be fully reversible. The welfare burden of managed pannus is low; the welfare burden of neglected pannus is substantial and unnecessary.

What You Can Do

Apply prescribed topical medications consistently — even when the eye appears to look normal
Protect affected dogs from intense UV exposure with UV-blocking canine goggles when appropriate
Avoid high-altitude environments or compensate with increased treatment frequency
Schedule regular follow-up examinations to allow your vet to adjust treatment intensity
Learn to recognize signs of treatment failure: increasing pigment, cloudiness, or squinting
Never discontinue treatment without veterinary guidance, even during apparent remission
