Ectopia lentis : ウィキペディア英語版 | Ectopia lentis
Ectopia lentis is a displacement or malposition of the eye's crystalline lens from its normal location. A partial dislocation of a lens is termed ''lens subluxation'' or ''subluxated lens''; a complete dislocation of a lens is termed ''lens luxation'' or ''luxated lens''. ==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).
