Cataracts in cats

Cataracts Could Be the Problem.

Cataracts are changes to the clear lens inside the eye, causing it to take on a cloudy appearance. The lens is a translucent disc-like structure inside the eye. The lens helps to focus incoming light in the back of the eye on the retina. This picture is then sent to the brain to allow a cat to see the world around them. When a cataract develops, the lens is not able to focus the light down, leading to vision changes.

The lens in a feline eye—like the lens in a human or canine eye—is a small, translucent structure that adjusts its shape as needed to focus incoming light rays on the retina, a light-sensitive tissue that lines the interior surface of the eyeball. When the retina receives light impulses that have passed through the lens, the impulses are instantaneously transmitted to the brain as visual information via the optic nerve, which is attached to the back of the eye. A cataract is a condition in which the lens becomes cloudy or totally opaque. When this happens, incoming light is impeded, if not totally prevented, from passing through the eye to the retina. In some cases, the affected area of the lens may be tiny, and the resulting impairment in vision will be inconsequential. In other cases, however, the entire lens may be opaque, in which case total blindness will result in an affected eye.
