Blepharophimosis syndrome is a genetic disease characterized by a shortening of the palpebral fissure or blepharophimosis, associated to ptosis and epicanthus inversus in most cases. The disease is transmitted in an autosomal dominant form with two well-identified clinical types. This is a presentation of a case of a family with three members affected: father and his two sons, referred from ophthalmology specialty because of palpebral ptosis. The clinical method was applied through the comparative or pattern technique. There was emphasis on the importance of delineating the phenotype for an early clinical diagnosis, a right comprehensive and multidisciplinary assessment, providing appropriate genetic counseling to the family.
