What is Retrobulbar Hematoma?
Retrobulbar Hematoma is a medical emergency where blood collects behind the eyeball (in the retrobulbar space), often due to trauma or surgical complications. This accumulation increases pressure within the orbit, potentially compressing the optic nerve and threatening vision. Prompt recognition and treatment are essential to prevent permanent vision loss.
What Causes Retrobulbar Hematoma?
Common causes of Retrobulbar Hematoma include:
- Blunt trauma to the eye or orbit (e.g., sports injury, assault, falls)
- Postoperative complication after orbital, eyelid, or sinus surgery
- Bleeding disorders or use of anticoagulant medications
- Rupture of blood vessels due to sudden increase in pressure
- Spontaneous hemorrhage, though rare
What Are the Symptoms of Retrobulbar Hematoma?
Symptoms typically develop suddenly and may include:
- Severe pain in or around the eye
- Bulging of the eye (proptosis)
- Decreased or loss of vision
- Double vision (diplopia)
- Eye movement restriction
- Eyelid swelling and bruising
- High pressure within the eye (orbital compartment syndrome)
These symptoms require immediate medical attention.
How Is Retrobulbar Hematoma Diagnosed?
Diagnosis involves:
- Clinical evaluation based on history of trauma or surgery and symptom presentation
- Ophthalmic examination including checking visual acuity, intraocular pressure, and eye movements
- Imaging studies such as a CT scan or MRI of the orbit to detect the hematoma and assess severity
- Monitoring for signs of optic nerve compression or orbital compartment syndrome
What Are the Treatment Options for Retrobulbar Hematoma?
Treatment is urgent and focuses on relieving pressure and preserving vision:
- Immediate lateral canthotomy and cantholysis (surgical procedure to decompress the orbit)
- Reversal or adjustment of anticoagulation therapy if applicable
- Administration of corticosteroids to reduce inflammation and swelling
- Pain management and monitoring of intraocular pressure
- Observation in mild cases with no vision impairment
Can Retrobulbar Hematoma Cause Complications?
Yes, without prompt treatment, it can lead to:
- Permanent vision loss from optic nerve damage
- Increased intraocular pressure and secondary glaucoma
- Ischemia of ocular tissues
- Long-term eye misalignment or motility issues
