Ectopia Lentis in Dogs and Cats
Although observed in humans and cats, ectopia lentis is most commonly seen in dogs. Ciliary zonules normally hold the lens in place. Abnormal development of these zonules can lead to primary ectopia lentis, usually a bilateral condition. Luxation can also be a secondary condition, caused by trauma, cataract formation (decrease in lens diameter may stretch and break the zonules), or glaucoma (enlargement of the globe stretches the zonules). Steroid administration weakens the zonules and can lead to luxation as well. Lens luxation in cats can occur secondary to anterior uveitis (inflammation of the inside of the eye).

He makes ‘em his own self and he’s glad when we come tell him they hurt. why, that’s a whole lot of pleasure to him, to be making up laws all the time and to have a crowd like us around handy to pass all his mean ones on. Why, that’s a whole everything under the sun! Next thing you know he’ll be saying cats can’t have kittens.”
