脂質 (膽固醇、磷脂質、三酸甘油酯) 在角膜基質沉積導致的白色至黃白色混濁。可為原發性 (角膜營養不良) 或繼發性 (全身性高脂血症、慢性角膜炎症後)。需區分原因以決定治療方向。
Feline glaucoma is usually secondary (uveitis, intraocular neoplasia). Iris melanosis may progress to diffuse iris melanoma and secondary glaucoma. Hypertensive retinopathy (retinal detachment, hyphema) is common in cats with CKD or hyperthyroidism — blood pressure monitoring is essential.
犬常見。原發性見於 Siberian Husky、Cavalier 等品種。繼發於甲狀腺功能低下的高脂血症也常見。
建議：依臨床狀況調整
監測頻率：青光眼 q4-6h（急性）；每次回診
穩定但需注意惡化徵兆，建議安排近期門診 (stable but monitor for deterioration, schedule near-term visit)
原發性角膜脂質營養不良預後良好，進展緩慢。繼發於高脂血症者控制血脂後可能改善。手術切除後可能復發。
Diagnostic Approach for Lipid Keratopathy
Menace response, PLR, Schirmer tear test, fluorescein staining, tonometry
Detailed anterior segment examination including conjunctiva, cornea, iris, lens
Direct and indirect ophthalmoscopy; ocular ultrasound if media opacity prevents visualization
