Congenital cystic eye: from prenatal diagnosis to therapeutic management and surgical treatment.

Only 28 cases of congenital cystic eye have been reported in the literature. The main issue in such cases is differential diagnosis between this malformation and different cystic malformations and masses of the orbital cavity and eyeball, the most common of which is microphthalmia with cyst. Both malformations arise from incomplete closure of the fetal optic vesicle in different stages of embryonic development. We present a case of congenital cystic eye, associated with coloboma and corneal dermoid of the fellow eye and with left brachiocephaly, discussing differential diagnosis with microphthalmia with cyst and illustrating the treatment we planned and performed. The patient first underwent a surgical excision of the left corneal dermoid, then a resection of the right orbital cyst. The last step was to perform a craniotomy and cranial vault remodeling. All the operations were planned and performed using a team approach. The team comprised an ophthalmologist, a plastic surgeon, and a neurosurgeon, and the result was a successful outcome.
