Tumors of the Choroid

There are several types of benign and malignant tumours that affect the eye and its different structures. The main intraocular tumours include:

 

What causes them?

Some tumours are congenital, such as 50% of all retinoblastomas that are passed on from one generation to another and affect 1 in every 15,000 newborns.

Others, such as intraocular melanomas, have no specific risk factors. Some can be associated with other syndromes, be secondary to conditions affecting adjacent areas or be due to a process of metastasis.

Treatments

Treatment of eye tumours depends on their type, location and size. Malignant tumours generally require removal through micro-incision surgery, which may be backed up with chemotherapy or local radiotherapy in coordination with an oncologist and has a great success rate.

For choroidal melanomas, the therapy of choice is normally brachytherapy, which consists of a radioactive ruthenium or iodine plate being located in the tumoural region for a few days. Given that it is local, it avoid external radiation and reduces any side effects, making it a minimally invasive option.

Furthermore, choroidal hemangiomas are often treated using photodynamic therapy and retinoblastomas with a combination of laser chemotherapy and cryotherapy.
