Tumour of the eye
Some tumours of the eye and the orbit, the area of the facial mass that contains the eye, can be difficult to treat. This is because the optic nerves and other structures of the eye itself, such as the retina, are sensitive to radiotherapy.
Melanomas of the eye, in particular, require high doses of radiotherapy that can be delivered by proton therapy or brachytherapy depending on the situation. Ocular melanomas are a major indication of proton therapy with the goal of treating the tumour while preserving sight when possible. Whether sight can be preserved also depends on the technical specifics to be assessed in order to better decide on the location of treatment.
The other two French proton therapy centres in Orsay and Nice have suitable equipment and long-standing expertise in the treatment of these melanomas of the eye.
