Dog Pannus: Chronic Superficial Keratitis in Dogs

Pannus is an immune-mediated eye condition in dogs causing corneal inflammation and vision loss if untreated.

Key Facts

German Shepherds are most frequently affected by pannus
UV light exposure worsens progression of the disease
Pannus is manageable but not curable and requires lifelong treatment
Cyclosporine and tacrolimus eye drops are first-line treatments
High altitude and sunny climates increase disease severity

Welfare Considerations

Pannus causes progressive corneal opacity leading to impaired vision and potential blindness. Affected dogs experience ocular discomfort and photophobia. Consistent veterinary management with immunosuppressive drops halts progression and preserves quality of life.

What You Can Do

Schedule regular eye exams for at-risk breeds
Use UV-protective dog goggles in bright conditions
Adhere strictly to prescribed eye drop schedules
Discuss long-term management plans with a veterinary ophthalmologist
Keep dogs out of intense midday sun
