Golden (leucistic) varieties are the same but lacking skin pigment, often they will have ghost markings of the original variety. Albinos usually have red eyes (no pigment so you see the blood vessels from the inside of the eye (iris)) and at least in the human form they often have eye problems due to this.
Edit: "Albinism: Humans, animals, and even plants can have this condition.
Most kids with albinism have problems with their eyes and have trouble seeing. For eyes to work properly, it's really important for them to have enough pigment.
The iris (the colored part of your eye) helps control the amount of light coming into your eye and hitting your retina, which is located at the back of your eyeball. When a person has albinism, the iris doesn't have enough color and can't shield the retina from light. So, people with albinism often have to wear glasses or contacts to help them see better. Outside, they usually need sunglasses or tinted contact lenses.
In addition to vision problems, with some kinds of albinism, a person might have trouble with his or her lungs, blood, kidneys, or other parts of the body."

http://en.wikipedia.org/wiki/Albino state that "a variety of problems with photosensitivity in eyesight and skin usually result from the condition" and many features of albinism probably apply to animals also (2004).
