title: [Look and nasal ventilation].
abstract: Ophthalmic manifestations of nasal obstruction can involve palpebral, orbital and ophthalmic disturbances. They can be the consequence of: directly with the nasal obstruction because the orbital cavity drains partly in the nasal fossae: rings, lipoptosis, blepharochalasis, fat protrusions, aggravation of exophthalmy in Grave's disease, enophthalmia. Oral breathing: there are modifications in the shape of the palpebral fissure ("round eye") by stretching of the facial mask and modifications of the orbital rims ("sad eye") due to lack of naso-sinusal expansion, often associated to malocclusion, there is a biomechanical correlation between the dental occlusion and the orbital area because of the presence of the maxillary sinus. Every occlusal disorder have an influence on projections of the supra and infraorbital rims.
