[Orbital hernias: new views of the pathogenesis, possibilities of correction]

The paper deals with the basic pathogenetic aspects of development of orbital hernias--the factors of a tarsoorbital fascial change in the presence of the hereditary syndrome of connective tissue hyperplasticity and elevated intraorbital pressure, which affects the volume of orbital fat. The possibilities of a differential diagnosis of orbital hernias and eyelid edemas are considered. There is a biomechanical association of orbital hernias with acquired age-related enophthalmos. The examples of impairments in the tolerance of the optic nerve and in the development of optic neuropathy in enophthalmos are considered. The fact that there may be tarsoorbital fascial lesions, followed by the development of orbital hernias after parabulbar injections is indicated. The author proposes an operation dealing with the reposition of orbital hernias instead of their resection during blepharoplastic interventions.
