The article provides data on the embryogenesis of the eyeball, nasolacrimal canal and nasal cavity. A frequent combination of congenital choanal atresia and anomalies in the development of the eyes was noted, most likely associated with the temporal and topographic parallelism of the intrauterine development of these anatomical areas. In order to assess the condition of the nasal cavity and choanal region in congenital eye pathology, 43 children with ophthalmological malformations were examined. In 32 (74.4%) children, according to endoscopic examination, changes in the anatomy of the choanal region with a change in its size in the form of incomplete atresia were revealed. The results obtained allow the authors to recommend that all children with congenital ophthalmological malformations be examined and monitored by an otolaryngologist with an endoscopic examination of the nasal cavity and nasopharynx.
