Delineation Information
- Modality
- MR
- Guideline
- Taken from Eekers DBP, Di Perri D, Roelofs E, Postma A, Dijkstra J, Ajithkumar T, et al. Update of the EPTN atlas for CT- and MR-based contouring in Neuro-Oncology. Radiother Oncol 2021;160:259–65. https://doi.org/10.1016/j.radonc.2021.05.013.
- Method
- Manual. The cornea is located at the anterior segment of the eyeball consisting of the structures ventral to the vitreous humor, the iris, ciliary body, and lens Using a brush of 2–3 mm the cornea can easily be delineated on MR as well as CT.
Anatomical Boundaries
- Cranial
- Superior most slice where the cornea is visible
- Caudal
- Inferior Most slice where the cornea is visible
- Lateral
- Upto the scleral margin
- Ventral
- Upto the scleral margin
- Dorsal
- Upto the scleral margin
