Orbital emphysema can be produced by trans-conjunctival migration of air from a high pressure airgun. In an industrial accident an 8 mm conjunctival laceration was produced in the superior fornix which acted as a portal of entry for air into the subconjunctival, subcutaneous, and retrobulbar spaces. Computed tomography revealed no evidence of orbital fracture and showed that traumatic orbital emphysema occurred without a broken orbital bone.

Orbital emphysema is usually described in association with fractures of the paranasal sinuses involving the orbit. We describe a rare form of orbital emphysema caused by high-pressure subconjunctival air injection from an air tube used in a garage, without apparent damage to the orbital walls.

Orbital emphysema is generally a benign, self-limited condition. However, if a fracture produces a ball-valve effect allowing air to enter but not to leave the orbit, and if the orbital septum remains intact, then extremely high intraorbital pressure and visual loss is possible. Two cases are described of visual loss from orbital emphysema, in a 33-year-old man and a 28-year-old man, which were successfully treated by a lateral canthotomy and cantholysis.

Orbital emphysema is a well-known clinical entity that has been considered benign and requiring no treatment. A case of marked orbital emphysema with simultaneous central retinal artery occlusion is described. The prompt relief of this occlusion following aspiration of air from the orbit suggests that orbital emphysema is an unreported cause of central retinal artery occlusion.

Orbital emphysema can occur after a blow-out fracture of the orbit, usually involving the medial wall. Repair of orbital floor fractures often involves the reduction of the herniated orbital contents and implantation of a sturdy, inelastic material to prevent the orbital contents from prolapsing into the maxillary sinus. We report a case of a maxillary sinus orbital fistula that occurred after the repair of a blow-out fracture of the right orbit, resulting in orbital emphysema. This was corrected with an autogenous fascia lata graft.

Orbital emphysema is radiologically apparent in 50% of cases of orbital fractures, but it is generally a benign, self-limited condition. However, visual loss may occur if a fracture produces orbital compression via a ball-valve effect, allowing air to enter but not leave the orbit. A case of compressive orbital emphysema complicated by ischemic optic neuropathy is reported. Intraorbital needle aspiration relieved the compression with improvement of visual acuity and normalization of intraocular pressure.

Orbital emphysema is not an uncommon finding following fractures of the facial skeleton. Both its significance as a threat to sight and its diagnostic value may well be underestimated. Fractures of the paranasal sinuses may occur as a result of indirect trauma. This article reviews the literature on the subject with particular reference to blindness as a possible sequel. Two cases of orbital wall fracture that occurred as a result of indirect trauma and which produced orbital emphysema are discussed.

Orbital emphysema without evidence of any significant trauma is a rare occurrence. A case is reported here of bilateral subcutaneous emphysema of the orbital, in the absence of facial skeleton trauma, in a healthy adult male following nose blowing. It assumes importance because of potential complications such as loss of vision due to pressure effects and infection. Lamina papyracea is the most common site of bony defect and point of air entry into the orbit. Spontaneous resolution in around two weeks is usual.

Orbital emphysema is a well-recognized complication of fractures involving the orbit. Commonly, this follows nose blowing and occurs in the subcutaneous tissues. A case of emphysema within the orbital cavity caused by the pressure changes during air travel is presented. The clinical picture was similar to that seen in retrobulbar haemorrhage and required early surgical intervention. Circumstances where patients at risk may be exposed to abnormal atmospheric pressures are highlighted and the management of the condition is discussed.

Orbital emphysema (OE) is usually the result of a fracture of lamina papyrecea or maxillary roof allowing air to pass from the sinuses into the orbit. OE without evidence of any significant trauma is a rare occurrence. Thorough literature search revealed that no case of OE due to the rupture of internal laryngocele has been reported. A case is reported here of bilateral orbitopalpebral emphysema associated with internal laryngocele, in the absence of facial skeleton trauma, in a healthy young adult male. It should be kept in mind that laryngocele rupture would be one of the underlying causes of OE or OE would be the presenting symptom of laryngocele rupture.
