A 13-year-old spayed Siamese had normal pupillary light reflexes and visual acuity, a dull haircoat , and a history of eating dog food. Binocular indirect ophthalmoscopy of the left fundus revealed an ellipsoid, hyperreflective lesion in the area centralis and a second lesion medial and adjacent to the optic disk. The right fundus had a hyperreflective band from the temporal to nasal quadrants. The plasma taurine level was 10 nmol/g (normal greater than 100 nmol/g). Central retinal degeneration secondary to taurine deficiency was diagnosed. Inclusion of fresh meat and fish in the cat's diet halted progression of the lesions.
一只13岁已绝育的暹罗猫，瞳孔对光反射和视力正常，被毛暗淡，有食用狗粮的病史。左眼眼底双眼间接检眼镜检查发现中央区有一个椭圆形、高反射性病变，以及视盘内侧相邻处的第二个病变。右眼眼底从颞侧象限到鼻侧象限有一条高反射带。血浆牛磺酸水平为10 nmol/g（正常大于100 nmol/g）。诊断为牛磺酸缺乏继发的视网膜中央变性。在猫的饮食中添加鲜肉和鱼可阻止病变进展。
