prevalence of intraocular injuries in patients with orbital blow-out fractures

Orbital roof blow-out fractures.

The term blow-out fracture was co ined by Smith and Regan [1] to describe an orbital floor fracture caused by a very sudden increase in intraorbital pressure without concomitant fracture of the orbital rim . Most blow-out fractures involve the orbital floor. Less often the medial orbital wall is fractured either solely or in conjunction with a fracture of the floor [2]. Upward displacement frac...

Orbital blow-out fractures: long-term visual outcome of associated ocular injuries.

Severe ocular injuries are uncommon in patients with pure orbital blow-out fractures. Over a 3-year period, 45 patients with radiologically proved blow-out fractures were reviewed by an ophthalmologist. Decrease in visual acuity was the main clinical finding accompanying significant eye injury. Although most eye injuries were transient, early ophthalmic assessment is recommended to exclude pote...

Orbital blow-out fractures in children: characterization and surgical outcome.

BACKGROUND Trapdoor-type orbital fractures usually associated with marked motility restriction are common in the pediatric age group. We reviewed the characterization and surgical outcomes of orbital blow-out fracture in children. METHOD This is a retrospective review study. From Jan. 1997 to Dec. 2006, 75 patients under 18 years of age with orbital blow-out fractures were seen in the departm...

Orbital blow out fracture.

Role of medial orbital wall morphologic properties in orbital blow-out fractures.

PURPOSE This study compares medial orbital wall supporting structures in patients with isolated inferior and medial wall fractures. METHODS The morphologic properties in all consecutive patients with periocular trauma who underwent orbital computed tomography (CT) scans from January 2004 to March 2006 were reviewed. On CT scans, the size of the fracture, the number of ethmoid air cell septa, ...

Blow-out fracture of the orbital floor.

Six patients with blowout fractures of the orbital floor, not associated with infraorbital rim fractures, are presented. Diplopia, infraorbital anesthesia and enophthalmos following blunt trauma to the eye should alert the examiner to the possibility of a blowout fracture with incarceration of extraocular tissues. Early roentgenographic examinations are often difficult to evaluate because of pe...
