先天性遺傳性角膜非炎症性退化疾病,為雙側對稱性病變。依受累層分為上皮型、基質型與內皮型。基質型 (脂質/結晶沉積) 最常見,表現為角膜中央白色至灰色不透明沉積。
貓罕見。Manx 品種有報告。
犬常見。Siberian Husky (基質型)、Boston Terrier (內皮型)、Cavalier King Charles Spaniel、Airedale Terrier 好發。
建議:依臨床狀況調整
監測頻率:青光眼 q4-6h(急性);每次回診

需系統性診斷與治療計畫,延遲可能影響預後 (systematic workup needed, delay may affect prognosis)
基質型預後良好,多數終生不顯著影響視力。內皮型進行性惡化,最終可能需角膜移植。受影響犬不建議繁殖。
角膜營養不良 診斷流程
評估角膜混濁特徵和品種背景
進行裂隙燈和其他眼科檢查
確定角膜營養不良類型並排除其他角膜疾病
