Orbital Disease
The orbit is the bony socket that
surrounds the eye. It contains the eye, arteries, muscles, and
nerves; all of which are cushioned by supporting membranes and
fat. Numerous medical and surgical problems may affect the
orbit. Orbital Fracture
Trauma may cause fracture of the orbital bone
surrounding the eye. If not treated, such fractures may result
in deformities of the face or in double vision.
Blunt trauma to the eye and bones around the eye
(such as by a fist) can lead to a fracture in the thin bones of
the orbit behind the eye. Anyone with such injury should seek
out a complete eye examination to rule out any other eye injury
promptly. The floor and inside wall of the orbit are especially
thin, and sinuses are on the other side of the bone. Blunt
trauma can cause what is termed a "blow-out fracture", where the
sudden rise in pressure in the orbit literally blows a fracture
through the bone and into the sinus. If this involves the floor
of the orbit, the cheek below the eye and upper gums in the
mouth can often become numb due to damage to a sensory nerve
that runs in the floor of the orbit.
If the fracture of large enough, the contents of
the orbit can start to slip into the sinus, and the eye will
appear to sink backwards. Sometimes an eye muscle can get
trapped in an orbital fracture and become stuck. This leads to
double vision especially if looking up, with pain. A CT scan of
the orbit can diagnose fractures and entrapment of muscles.
Entrapped muscles often have to be released surgically.
Antibiotics are usually given after an orbital fracture, due to
risk of infection from the sinus into the orbit.
Orbital Inflammation (Orbital Infection or
Orbital Cellulitis) An
infection of the orbit, or boney eye socket, can lead to severe
symptoms, one of which is double vision. Usually orbital
infection spreads from adjacent sinuses, and sometimes from a
skin or eyelid infection. Symptoms include pain, eyelid swelling
and possibly a lump behind the eyelids that can be felt, eye and
eyelid redness, discharge, blurred vision, eye displacement or
protrusion, and double vision. The double vision comes from the
infection preventing normal movement of the eye, and a
misalignment may occur in certain positions of gaze. People with
this condition are usually treated in the hospital with IV
antibiotics. Diabetics are subject to a particularly severe and
destructive fungal orbital cellulitis.
Orbital pseudotumor ("like a
tumor") is an inflammatory condition which can simulate tumor or
infection, but usually responds to steroids. A CT scan or MRI is
usually done in cases of orbital infection, tumor, or
pseudotumor to help make the diagnosis and guide treatment.
Orbital Tumors
Tumors may develop in any of the various tissues within the
orbit and may also invade the orbit from the sinuses, brain, or
nasal cavity, or it may metastasize (spread) from other areas of
the body. Orbital tumors can affect adults and children.
Fortunately, most are benign.
What are the symptoms of an
orbital tumor? Symptoms
of an orbital tumor may include protrusion of the eyeball
(proptosis), pain, loss of vision, double vision, redness,
swelling of the eyelids, or an obvious mass. Some tumors are
visible and therefore easily identified, while others may not
exhibit symptoms until they are large enough to displace the
eyeball. Prominence of the eyes is not necessarily the result of
a tumor, but may result from inflammation such as that caused by
Thyroid Eye Disease. In children, parents may first notice a
droopy eyelid or slight protrusion of the eye.
Orbital tumors are most
frequently diagnosed with either a CAT scan or MRI. If either of
those tests look suspicious, a biopsy may be performed.
How are orbital tumors
treated? Treatment of
orbital tumors varies depending on the size, location, and type.
Some orbital tumors require no treatment, while others are best
treated medically or with the use of radiation therapy. Still
others may need to be totally removed by either an orbital
surgeon or a neurosurgeon, depending on the particular case.
After removal, additional radiation or chemotherapy may be
required. Surgery has become much safer because CAT scans and
MRI testing can help pinpoint the location and size of the
tumor.
Final Reminders
To effectively treat the many varied conditions
of the orbit requires a special understanding of the anatomy and
pathophysiology of the orbit. Fellowship in the American Society
of Oculo-facial Plastic and Reconstructive Surgery (ASOPRS)
indicates that the surgeon has greatest specialized training and
expertise in treating patients with orbital problems.
If you have problems related to the orbit,
please consult with Dr. Kass who is fully trained to treat these
problems and has been in practice in Tampa Bay for over 20
years.
