Sections:
The ora serrata (plural: orae serratae) is the most anterior extent of the retina. This serrated transitional zone lies between the anterior margin of the retina and the ciliary bodies.
Radiographic features
MRI
Ora serrata cannot be seen on conventional imaging but is an inferred reference point. On the axial plane, it is located at the 2 and 10 o'clock position of the globe immediately posterior to the ciliary bodies. Knowledge of this reference point is vital as a retinal detachment will not extend beyond the ora serrata. In contrast, a choroidal detachment can extend anteriorly and beyond the ora serrata.
