Assessment of optic disc parameter changes in head and neck cancer patients undergoing radiotherapy based on OCT

Radiotherapy to the head and neck can lead to significant changes in the structure of the optic disc, especially in choroidal microcirculation and some retinal regions. OCT, as a non-invasive imaging technique, can detect these changes early and provide a basis for early intervention by clinicians to reduce the impact of radiation-related ocular complications on patients' visual function. Future studies should further explore the potential effects of radiotherapy on optic disc function and assess the effects of preventive and therapeutic interventions.
