Mechanical damages Г. can be rather various, from easy traumas a century up to traumas with размозжением an eyeball, wound of walls of an eye-socket and its{her} contents, the various combined wounds of a skull and G.Povrezhdenija of an eyeball can be superficial, not accompanying through wound of the external environment Г., penetrating; besides distinguish G.Oni's stupid{blunt} traumas arise basically from impact on Г. a processable detail, a stick, the jumped aside knot at cabin of fire wood, a fist, etc. At stupid{blunt} traumas Г. haemorrhages under конъюнктиву, in the forward chamber, in стекловидное a body can be observed. There can be отрыв радужки at its{her} root, so-called иридодиализ, a displacement of a crystalline lens, his{its} turbidity, having dug склеры. Superficial and penetrating damages of. Are rendered more often cutting or колющими by subjects, arise at explosions, can be accompanied by introduction of alien bodies in конъюнктиву, a cornea, склеру, and at penetrating wounds and in G.Odnim's cavity from the basic attributes of wound Г. the pain is. At superficial damages of a cornea the photophobia, слезотечение is marked, at damage конъюнктивы haemorrhages are possible{probable}. An attribute of penetrating wound Г. is the relative softness of an eyeball arising owing to the expiration of an aqueous moisture and стекловидного of a body. Depending on a degree of infringement of an integrity of external wall Г. the wound can gape, in it{her} environments Г., стекловидное a body, a crystalline lens can drop out. Frequently thus haemorrhages in a lobby камору and стекловидное a body are observed. At connection of an infection the purulent inflammation of панофталъмит can develop. Very heavy complication of penetrating wound Г. is disease of the second eye - so-called sympathetic офтальмия. Treatment of patients with trauma Г. should carry out{spend} врачокулист.
