This is the third of our cases of ocular trauma and
0:05
this one is a little less subtle.
0:07
In this case, once again,
0:09
we are looking at the right globe and we see that
0:14
the anterior chamber cannot be distinguished.
0:17
The lens of the eye which is seen on the left side
0:20
normally, cannot be seen in the right eye.
0:25
It has been disrupted.
0:27
And we also see that the vitreous and the
0:31
shape of the vitreous is flattened.
0:35
This patient has a through and through injury to this globe
0:40
where both the anterior chamber has been ruptured,
0:43
the vitreous has been ruptured.
0:45
There likely is a wooden foreign body,
0:48
low density on the CT scan and we have hemorrhage in the
0:53
vitreous, as well as the anterior chamber and
0:55
complete disruption of the lens of the eye.
1:00
When one sees that the shape of the globe is as
1:06
flattened as it is on these serial images,
1:10
we sometimes will use the term ocular hypotony,
1:14
representing the low-pressure state of the globe,
1:18
which allows it to look like a flat tire or flattened out.
1:23
This globe is unlikely to be salvaged, and the
1:27
patient is likely to have enucleation.
