Hypotelorism is a medical condition pertaining to abnormally close eyes. ==Causes== It is often a result of fetal alcohol syndrome (FAS) caused by large alcohol intake in the first month of pregnancy. It can be associated with trisomy 13 which is also known as Patau syndrome, as well as hereditary neuralgic amyotrophy.〔Electromyography and Neuromuscular Disorders, Second Edition.
