Abstract: There are many names for infraorbital dark circles in children,which are confusing,and there are few epidemiological studies.Although the local pathology is clear,the fundamental etiology is controversial.Analysis of the local anatomy of the inferior palpebral vein,infraorbital vein,lacrimal venous plexus,facial vein,suborbital space and infraorbital lymph nodes has shown that the possibility of obstruction of infraorbital venous return caused by nasal and adenoid diseases is greater.Traditional Chinese medicine classics have rich discussion on dark circles,and there is a close correlation between the eyes and the five viscera in terms of physiology and pathology,especially the liver,spleen,and kidney.In addition,the meridian theory and the theory of qi,blood and body fluid can also explain this phenomenon,not just "spleen deficiency".Misdiagnosis and missed treatment should be avoided in clinical practice.
