Congenital microblepharospasm refers to microblepharospasm syndrome, which can be detected by genetic testing before birth. Microblepharospasm syndrome is an inherited condition, an autosomal dominant disorder that is associated with a genetic abnormality. Usually, if one parent has microblepharospasm syndrome, the offspring may develop the condition. Genetic testing can be done on amniotic fluid before birth to find out if the child has the condition. Surgery can be considered to correct micrognathia, and a postnatal examination is required to design a specific surgical plan, which usually involves a combination of surgeries, such as medial canthoplasty, levator ani shortening, and so on. It is recommended that patients with microblepharospasm syndrome be seen promptly for evaluation of their condition and treatment as prescribed by their physician, and that prenatal counseling be performed for genetic problems in their offspring.
