How Does Proton Eye Therapy Work?

The treatment produces low energy protons which are specifically suited to treating tumours of the eye. Different from other radiotherapy methods, the energy of the beam stops at a specified depth within the body, allowing healthy tissue beyond the beam to be spared from any potential side effects.

Choroidal melanoma is the most common eye tumour which is treated by Proton Therapy. However, treatment can also take place for other eye cancers such as:

• Choroidal haemangiomas
• Iris melanomas
• Conjunctival melanomas

Proton Eye Therapy treatment works by disabling tumour cells so they’re unable to reproduce and is given as four daily sessions, typically lasting about 20 minutes. However, the therapy itself takes only around 30 seconds.

Clatterbridge accepts referrals from four specialist hospitals in Liverpool (St Paul’s Eye Unit), London (Moorfields Eye Hospital), Sheffield (Royal Hallamshire Hospital) and Glasgow (Gartnavel General Hospital).
