- Genetics: Certain breeds are predisposed to cataracts.
- Diabetes: Diabetic cats are at higher risk of developing cataracts.
- Uveitis: Inflammation inside the eye can lead to cataract formation.
- Trauma: Injury to the eye can cause cataracts.
How Do Cataracts Progress in Cats?
Cataracts can progress gradually, starting as small opacities in the lens and eventually covering the entire lens, leading to vision loss.
What Are the Treatment Options for Cataracts?
The primary treatment for cataracts is surgical removal of the clouded lens, followed by the implantation of an artificial lens. This procedure can restore vision in many cats. According to research from the Veterinary Vision Center, cataract surgery has a high success rate in cats, significantly improving their quality of life.
6. What Role Does Eye Discharge Play in Apparent Eye Color Changes?
Eye discharge, caused by infections or allergies, can accumulate and alter the apparent color of the eye, making it appear different.
What Types of Eye Discharge Are Common in Cats?
- Clear Discharge: Often associated with allergies or mild irritation.
- Yellow or Green Discharge: Typically indicates a bacterial infection.
- Brown or Reddish Discharge: May suggest a viral infection or the presence of blood.
What Infections Can Cause Eye Discharge and Color Changes?
Common infections that can cause eye discharge include feline herpesvirus, chlamydia, and mycoplasma. These infections can also lead to inflammation and changes in the eye’s appearance.
How is Eye Discharge Treated in Cats?
Treatment depends on the underlying cause and may involve:
