Bilateral lens subluxation through a crystalline lens ectopia in a girl of 7 years: what diagnosis

The ectopia lentis, primitive congenital malformation enters usually as part of a malformation syndrome (Marfan's syndrome, homocystinuria, Weill Marchesani's syndrome). The discovery of a case imposes an etiological investigation and family screening. The authors present a case of ectopia lentis in a girl of 7 years old in which the table of Marfan's syndrome was not complete, and the assay of homocysteine was normal. The authors evoke today the diagnosis of nonspecific conjunctival disease. The signs of Marfan's syndrome are emerging with age which justifies regular monitoring by ultrasound of the heart in search of a widening of the aortic root considered as a major sign of this pathology
