I show this case as an excellent example of how thyroid
0:04
eye disease or thyroid orbitopathy
0:07
can cause unilateral proptosis.
0:10
Here we have a patient who has left
0:12
sided exophthalmos or proptosis.
0:15
This is also an excellent example of how you
0:18
can have involvement of the muscle belly
0:23
with sparing of the tendinous insertion of the muscle.
0:27
This patient also has lacrimal gland which
0:30
is anteriorly located within the orbit.
0:34
Let's scroll through this a little bit more.
0:36
You can see that the patient has marked enlargement of
0:39
the superior rectus muscle on the left
0:42
side compared to the right side.
0:45
We have increased orbital fat on the left side compared
0:49
to the right side. But note, however,
0:52
that the optic nerve at the optic canal and orbital
0:56
apex still has fat on either side of it,
1:00
and therefore this patient would not necessarily need
1:04
orbital decompression for thyroid eye disease.
1:08
The inferior rectus muscle is markedly enlarged
1:13
on the left side compared to the right side.
1:16
So unilateral exophthalmos associated with thyroid
1:19
orbitopathy without compression of the optic nerve,
1:24
but with demonstration of the lacrimal
1:27
gland being protruded anteriorly.
