Corneal Dystrophy vs. Corneal Degeneration: What's the Difference?
Have you ever been told your pet has a white or cloudy spot on their cornea? While corneal dystrophy and corneal degeneration may look similar, they are actually very different conditions.
✨ Corneal Dystrophy
• Usually inherited and often seen in younger dogs.
• Typically affects both eyes.
• Appears as white or gray deposits within the cornea.
• Usually is not painful
• In many cases, no treatment is needed—just regular monitoring; other patients benefit from daily eye drops
⚠️ Corneal Degeneration
• Develops secondary to another eye problem such as chronic inflammation, previous injury, dry eye, or aging changes.
• Typically seen in older dogs
• May affect one or both eyes.
• Mineral or lipid deposits can develop in damaged areas of the cornea.
• Unlike dystrophy, degeneration can be associated with painful corneal ulcers and may require treatment.
• Successful management depends on treating the underlying cause.
Although these conditions can appear similar, determining which one your pet has is important because the treatment and long-term outlook are very different.
