[Congenital serous cyst of the orbit with anophthalmos].

The authors reported a case of orbital congenital serous cyst with anophtalmos. It was a third type of Duke Elder classification. Although it looked sporadic, this malformation is hereditary and due to a disharmony between optic cup growth and differenciation. Ultrasonography and scanner could confirm the diagnosis and helped to discard orbital and eyelid angioma and meningocele. After excision, a prosthesis must be adapted in the orbit.
