[Ophthalmic manifestations of nasal obstruction]

Ophthalmic manifestations of nasal obstruction can involve palpebral, orbital and ophthalmic disturbances. They can be the consequence of -Direct contact with the nasal obstruction because the orbital cavity drains partly in to the nasal fossae: rings, lipoptosis, blephaochalasis, fat protrusions, aggravation of exophthalmy in Grave's disease. -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 a lack of naso sinusal expansion, often associated with malocclusion. -A biomechanical correlation between the dental occlusion and the orbital area because of the presence of the maxillary sinus. Every occlusal disorder has an influence on projections of the supra-and infraorbital rims.
