Having dealt with the ocular lesions this far,
0:03
we're now going to move into the
0:05
other portions of the orbit.
0:07
These are organized according to the intraconal space
0:14
and the conal space, including the muscle cone.
0:18
And then we will also deal with extraconal lesions,
0:21
largely around the paranasal sinuses,
0:23
bone and fat and nerves.
0:26
So we'll begin classically with the intraconal
0:29
space, and as you can see,
0:30
it's going to be dominated by the optic
0:32
nerve and the optic nerve sheath,
0:34
as well as the retrobulbar fat and the nerves and
0:38
vessels that run through the retrobulbar fat.
