Normal tissue tolerance to external beam radiation therapy: Eye structures

摘要

The radiation dose received by the eye depends on the pathology, tumour location (ocular globe, orbit, neighboring structures) and the radiation technique. The major complication is the complete loss of vision, which is often multifactorial. This article, based on a literature review, describes the radiation effects and the tolerance doses for all eye structures: cornea, lens, retina, optic nerves, orbit and ocular adnexa.
