Choroidal Haemangioma

What is Choroidal Haemangioma?

  • This is a benign growth of a vascular lesion within the choroidal layer of the eye.
  • As this is a benign lesion, it does not require treatment unless it starts to leak and threaten the vision.
  • The correct diagnosis of this lesion is imperative as it can mimic the appearance of a choroidal melanoma which is a malignant tumour.
  • Treatment of choroidal haemangiomas may involve PDT laser or radiation therapy.

PDT Laser

  • This procedure is performed in the clinic, usually on a separate appointment.
  • The patient receives a special dye injection into the veins which is then activated by the PDT laser performed directly to the lesion in the eye.
  • The photosensitive dye circulates throughout the body and patients are advised to bring a hat and to avoid exposure to sunlight for a few days following the procedure.

Plaque Radiation Therapy

  • Plaque radiation therapy or plaque brachytherapy is a treatment where focal radiation is delivered to the tumour inside the eye by suturing a radioactive plaque to the outside of the eye.
  • This focused delivery allows the sparing of critical structures of the eye and body from unnecessary radiation damage.
  • This treatment involves two separate operations, usually a few days apart. The first operation is to insert the radioactive plaque and the second operation to remove it from the eye.
  • These procedures are performed under general anaesthesia at the Royal Adelaide Hospital.
  • Following insertion of the plaque, the patient is admitted to the hospital as an in-patient until the second operation. Visitors are allowed.
  • After the second operation, the patient can be discharged home with eye drops to use.
  • This procedure has a very high success rate of greater than 90% to treat the tumour in the eye.
