Several eye signs may present secondary to altered blood lipid levels. It is important to recognize these signs and their implications relative to both primary and secondary hyperlipoproteinemias. The significance of corneal arcus is age related, while isolated xanthelasma implies altered blood lipid levels in 30-50% of the cases. Eruptive xanthomas imply triglyceride levels in excess of 1500 mg% while lipemia retinalis presents when triglyceride levels exceed 2500 mg%. Retinal emboli present as a sign of an eroding atheroma and as such an indicator of the possibility of an impending stroke. Altered blood lipid levels represent a threat to life and must be recognized as early as possible to institute therapy. Therapy may be directed to either the primary or secondary causes of hyperlipoproteinemias.
血脂水平改变可能会出现几种眼部体征。认识到这些体征及其与原发性和继发性高脂蛋白血症的关系很重要。角膜弓的意义与年龄相关，而孤立性睑黄瘤在30%至50%的病例中意味着血脂水平改变。疹性黄瘤意味着甘油三酯水平超过1500mg%，而当甘油三酯水平超过2500mg%时会出现视网膜脂血症。视网膜栓子是动脉粥样硬化侵蚀的体征，因此是即将发生中风可能性的指标。血脂水平改变对生命构成威胁，必须尽早识别以便进行治疗。治疗可针对高脂蛋白血症的原发性或继发性病因。
