Abstract: Some diseases or congenital abnormalities cause a certain pattern of facial changes, which are important for disease screening and diagnosis. Duringlast ten years, face recognition technology has been applied in the diagnosis of endocrine diseases such as acromegaly, Cushing's syndrome, and genetic syndromes such as Down syndrome and Cornelia de Lange syndrome.The detection rates of face recognition technology are not less than, in some cases even higher than,those of clinical workers.More importantly, this technology has more value in identifying patients with endocrine disease in the early stage. The technology is expected to be applied to the screening of endocrine diseases and genetic syndromes, to shorten the delay period before diagnosis and to help the staging of endocrine diseases.

Key words: face recognition technology, medical diagnosis, acromegaly, Cushing’s syndrome, genetic syndrome
