What it is
The cornea is the clear front window of the eye, and it stays clear only while its layers are neatly ordered and kept free of excess water. In corneal dystrophy, fat or minerals settle within those layers, or the inner layer of cells that pumps water out stops working well, and the window turns hazy in patches.
The condition is inherited and tends to affect both eyes. Depending on the form, it can show up in young adult dogs or later in life, and the changes may stay almost the same for years or slowly spread.
A dog can live with these spots without any discomfort and cope well at home and on walks. Where the cornea swells, it can become more fragile and develop sores, so a watery, red or squinting eye deserves attention.
Signs you may notice
- White or silvery spot in the eye
- Glittering haze on the cornea
- Changes in both eyes
- Red or watery eye
- Squinting or rubbing the eye
You may notice a white, silvery or greyish, sometimes glittering spot or oval in the cornea, and both eyes can be affected. If the eye turns red, waters, or the dog squints or rubs it, it should be seen by a vet.
When to see a vet
Book a visit when you first notice a cloudy spot in the eye, and contact a vet soon if the eye turns red, waters, or the dog squints or rubs it, as this can mean a painful sore.
