What is a orbital hematoma?

What is a orbital hematoma?

Orbital hematoma is defined as a collection of blood inside the orbit, and the major adverse sequelae that develop arise because the orbit is a bony cone with tight fascial attachments holding the globe at its anterior edge.

How do you treat an orbital hematoma?

Decrease of vision or blindness caused by orbital hematoma may be improved through a lateral canthotomy as emergency measure and subsequently by draining the hematoma to relieve compression of the optic nerve.

What causes Retrobulbar hematoma?

RBH can occur due to orbital trauma, complication of eyelid or orbital surgery, or any process that can affect blood supply to the eye, such as arteriovenous malformations, orbital varicosities, or lymphangiomas.

How do you treat a retrobulbar hematoma?

The majority of retrobulbar hemorrhages can be managed conservatively with digital ocular massage or intravenous acetazolamide or mannitol. However, further surgical intervention is indicated when vision is at risk.

What causes orbital hemorrhage?

A non-traumatic or spontaneous orbital hemorrhage (NTOH) is usually caused by the presence of an orbital mass, an inflammation, an infection, a bleeding disorder or those called idiopathic.

What is retrobulbar hematoma?

Retrobulbar hematoma is a condition that involves blood congestion deep in the soft tissue of the posterior orbital septum. Although this is a rare complication, it requires considerable caution because it can cause blindness.

What is retrobulbar haematoma following blunt orbital trauma?

Retrobulbar haematoma following blunt orbital trauma is a rare, but potentially serious, complication, since it can evolve rapidly from visual impairment to permanent loss of vision.

What is a retrobulbar hemorrhage of the eye?

Retrobulbar hemorrhage is the presence of a post septal orbital hematoma and is usually due to craniofacial trauma causing an extraconal hematoma. It may cause orbital compartment syndrome which is an ophthalmologic emergency. If small, there may be no orbital or ocular symptoms.

What is the main finding of a left retroorbital hematoma?

Main finding is 27mm acute hematoma within the inferior left retro-orbital space extending into the left maxillary sinus causing superior, lateral and anterior displacement of the globe. The inferior rectus muscle is not clearly visualized. Optic nerve appears to be intact.

What is included in the medical history of orbital hemorrhage?

Upon encountering a patient with an orbital hemorrhage, one should quickly obtain a brief medical history identifying the mechanism of hemorrhage (e.g., recent surgery, accidental trauma, spontaneous, etc.). Visual acuity should be measured, and the pupils carefully assessed.
