Teletherapy: advanced techniques

Radiotherapy has been utilized as a treatment for ophthalmologic processes for more than one hundred years. Over this century, the field of ophthalmologic oncology has been revolutionized through medical discoveries, development of novel surgical interventions, and innovation of advanced radiotherapy techniques. In this chapter, novel radiotherapy techniques are considered. Material presented will build on basic radiation therapy principles, techniques, and treatment parameters established in the previous chapter through consideration of intensity modulated radiotherapy, stereotactic radiotherapy, and heavy ion therapy. Deliberation of matters common across advanced radiotherapy techniques including target delineation, treatment planning, and requisites for ensuring accurate, precise treatment delivery will precede discussion of advanced radiotherapy techniques as applied to the management ophthalmologic malignancies.
