Eye Tumor

Tumors and swellings can take place behind the eye. They typically push the eye forward causing a bulging of the eye called proptosis. The most typical causes of proptosis are thyroid eye disease and lymphoid tumors (lymphoma and irregular lymphoid hyperplasia).

Other tumors include vascular tumors (e.g. hemangiomas, lymphangioma, hemangiopericytoma), lacrimal gland tumors (e.g. dacryoadenitis, benign combined tumor, sarcoidosis and adenoid cystic cancer), and developments that extend from the sinuses into the orbit (e.g. squamous cancer, mucocele). Metastatic cancer can likewise originate from other parts of the body to form an orbital tumor. Lastly, an orbit tumor can likewise be triggered by inflammation (e.g. pseudotumor, sarcoidosis) or infection (abscess).

Eye Tumor Symptoms

Most patients with eye tumors see a bulging of the eyeball or double vision (diplopia). Infections, swellings and specific eye cancers can likewise cause pain. Less frequently, eye tumors might be an incidental finding on CT or MRI of the head, sinuses and orbit.

Symptoms of eye tumor may consist of:

  • bulging of one eye
  • total or partial loss of sight
  • pain in or around the eye (uncommon with eye cancer).
  • a pale raised lump on the surface area of the eye (the conjunctiva or cornea).
  • blurred vision.
  • change in the look of the eye.

How Is Eye Tumor Diagnosed

Though CT, MRI’s and ultrasound can help in determining the probable diagnosis, the majority of eye tumors are diagnosed by a surgical biopsy called an orbitotomy (anterior or lateral). A specimen is sent out to an ophthalmic pathologist who assists determine the exact medical diagnosis.

Treatments for Eye Tumors

When possible, eye tumors are absolutely gotten rid of. If they can not be removed or if elimination will cause excessive damage to other important structures around the eye, a piece of tumor may be gotten rid of and sent out for assessment by an eye-pathologist. Sometimes an eye tumor is too big or includes the sinuses and needs more extensive surgery with bone-flaps.

If tumors can not be removed during surgery, many eye tumors can be treated with external beam radiation therapy. Certain uncommon eye tumors need elimination of the eye and orbital contents. In particular cases orbital radiotherapy might be used to treat any recurring tumor (in an effort to extra vision and the eye).

When Does Surgery Require for Tumor Behind Eye?

If the tumor is small and not symptomatic, it might be followed securely with serial MRI scans. When ocular symptoms such as visual loss or disfiguring proptosis are related to mass impact from the eye tumor, surgical removal is typically the best alternative.

The area of the sore directs the surgeon toward picking the most suitable type and location of the orbitotomy. Numerous cutaneous and bony techniques to the orbit have actually been explained. In general, when eye tumors are positioned lateral to the optic nerve, a lateral orbitotomy is carried out. Tumors exceptional to the optic nerve or those with intracranial extension are generally approached via an orbitofrontal craniotomy. Tumors listed below the optic nerve can be approached by means of a median orbitotomy, a transethmoid or a transmaxillary method.

When an orbital meningioma or fibrous dysplasia is accompanied by hyperostosis of the optic canal, craniotomy is usually accompanied by bony decompression using a high-speed diamond drill. When the tumor is not completely eliminated surgically, this subtotal resection may be followed by some kind of orbital irradiation.
