An on-line clinical folder has been optimised in order to manage all the av
ailable data coming from eight years of choroidal melanoma treatment with p
roton beams. The system allows the ophthalmologist, in a very easy way, to
record and update, in different display sessions, the required data coming
from the usual eye specialised visit, the tumour determination and identifi
cation, all the radiotherapy treatment information and the clinical data de
rived from the post-treatment follow-up visits. The goal is a better patien
t cure coming from statistical data treatment. This field is of great inter
est in oncology because only with analytical correlation study among the ir
radiated dose to the tumour and the relevant parameters of die tumour itsel
f, is possible to optimise the used treatment planning.
