Current Concepts, New Techniques, Clinical Challenges
Starts by reviewing ocular oncology services offered at UBC including a list of all the diseases and the following treatment technologies:
- Proton therapy
- External beam radiation
- Iridocyclectomy/Eye wall resection
Gives a case example of a patient to show how brachytherapy can be very effective.
Shows calculations of how much radiation gets delivered to the sclera and ultimately the choroidal tumor with the maximum dose. These are all custom made and can get into tight corners.
For proton beam, must aim the treatment again at the tumor but in this case with the patient sitting upright.
AJCC TNM 7 Tumour classification introduced in the past few years in place of the COMS classification.
Fundus auto fluorescence is interesting but not sure exactly what it tells us
OCT another recent technology being used.
