ENOPHTHALMOS (enophthalmus; Greek ep-the prefix meaning stay inside + ophthalmos of eyes) — the shift of an eyeglobe of a kzada owing to reduction of contents of an eye-socket or the sizes of an eyeglobe.

Distinguish the early, late and seeming enophthalmos. Early E. arises owing to the shift of bone walls of an eye-socket at their change directly after an injury or later a nek-swarm time. Late E. develops as a result of a secondary atrophy of retrobulbar cellulose and other tissues of an eye-socket after a stupid injury, and also as a result of hematomas of an eye-socket, inflammatory processes, disturbance of an innervation at defeat of cervical nodes of a sympathetic trunk; it can be connected with a lipodystrophy and age involution of body tissues, including eye-sockets, at persons of senile age, shown a subatrophy of cellulose of an eye-socket. Seeming E. it is caused by reduction of the sizes of an eyeglobe at its atrophy or inborn micro-ftalme.

At patients with E. the eyeglobe is located in an eye-socket more deeply, than normal, displaced kzad, the palpebral fissure is narrowed; at the same time deepening and retraction of an upper eyelid, formation of folds on it is observed. The combination E is possible. with a miosis (see), a ptosis (see), restriction of mobility of an eyeglobe. The decrease in sight connected with damage of an optic nerve or intraocular changes and expressed in various degree depending on a type of pathology is possible; sometimes there is a diplopia (see).

The diagnosis is based on data of the anamnesis, a characteristic clinical picture and results rentgenol. researches.

Treatment is directed to a basic disease. At E., connected with an injury of an eye-socket, normal situation of an eyeglobe is redeemed after reposition of the displaced bones or closing of bone defects of an eye-socket with transplants.

The forecast is more often favorable. At an enophthalmos of a traumatic origin or at inflammatory processes in an eye-socket perhaps considerable decrease in sight.
