Progressive retinal atrophy or “PRA” is a
condition where the retina deteriorates over time and eventually results in
blindness. Unfortunately, PRA cannot be treated, and your cat will have to
adapt as his sight begins to fail. Try to make his life a little easier by not
moving furniture around the home, and keep his belongings, such as his bed and
feeding bowl in the same place all the time.
As cats age, or if a cat suffers from
diabetes, he may develop cataracts, which is a condition where the eye becomes
opaque and cloudy. If left untreated, cataracts effectively result in
blindness. However, if treated early enough with surgery, your cat may still
enjoy the benefit of his sight for years to come.
Glaucoma occurs when there is an excessive
amount of fluid in the eye resulting in pressure upon the retina. A cat with
glaucoma will suffer a certain amount of pain due to this pressure, and like
cataracts, if left untreated may result in blindness. Your vet may recommend
medication in the form of eye drops and/or pills, or in some cases, surgery.
