Tumors are abnormal growths that occur when cells begin to expand out of control. They can be either benign (harmless) or malignant (cancerous). Orbital and adnexal tumors develop from tissue, such as from muscle, nerve, or skin around the eyeball. The orbit – also known as the eye socket – consists of the tissues surrounding the eyeball. The adnexal structures of the eye include the eyelids and tear glands.

Symptoms of orbital and adnexal tumors include:

  • Bleeding from the nose, particularly on only one side
  • Bulging eyeball
  • Change in vision or double vision
  • Change or loss of ability to smell
  • Closed appearance of the eyelid
  • Lump on your eyelid or eye that increases in size over time
  • Partial or total loss of vision
  • Redness of the eye
  • Shadows or flashes of light in your vision
  • Sinus pain, pressure, and infections


Imaging - Your ophthalmologist may recommend you undergo a computerized tomography (CT) scan, magnetic resonance imaging (MRI), or ultrasound to aid in the diagnosis of your tumor.

Biopsy - The best way for your doctor to accurately diagnose your orbital or adnexal tumor is for your doctor to surgically obtain a small tissue sample (biopsy) from the affected area, and then send it to the laboratory for analysis.


Surgery - When possible, your ophthalmologist will likely recommend the surgical removal of the tumor.

Radiation therapy - If the tumor cannot be removed surgically, you may need to undergo external beam radiation therapy to shrink and destroy the tumor.
