[A rare form of optical, choroidal and retinal dysplasia combined with an occipital encephalocele].

Report on the case of a female infant born with an occipital encephalocele and colobomas of the optic disc, chorioid, and retina. These clinical signs together with respiratory disturbances suggest a Joubert syndrome and a Pfeiffer syndrome. The differential diagnosis of these syndromes is discussed. An analysis of the clinical data indicates a genetic risk of 25% for further siblings.
