We are continuing in the series of cases regarding trauma.
0:04
So this is the T of vitamin C and D, vascular, infectious,
0:08
traumatic, acquired, metabolic, idiopathic, neoplastic,
0:11
congenital and drugs. In this case,
0:14
as we scroll from top to bottom,
0:17
we note the difference in the shape of the vitreous.
0:22
So, as opposed to the previous case
0:24
where we were more concerned
0:25
about the anterior chamber and its depth,
0:28
in this situation, we are looking at the vitreous.
0:31
The vitreous, as you recall,
0:33
is that portion behind the lens of the
0:36
eye and as one can see in this case,
0:41
you have less depth in the vitreous on the
0:45
right side compared to the left side.
0:48
If one were to use the windowing function,
0:51
one might even be able to state that the density of the
0:56
vitreous is more dense than the vitreous on the left side,
1:01
and hence we have blood within the vitreous humor.
1:06
This does not mean that you should not continue
1:08
to look at the anterior chamber,
1:11
which again appears to be more dense than
1:14
the anterior chamber of the left eye.
1:17
So this patient has both an anterior hyphema,
1:21
that is blood in the anterior chamber, as well as rupture
1:25
of the globe of the vitreous posterior segment,
1:28
as well as blood within the vitreous humor.
1:31
And this can be viewed if one scrolls continuously.
1:37
And we note that the shape of the globe on the right side
1:44
the globe on the left side.
1:46
If we stop on this image,
1:48
we note low density within the anterior
1:54
chamber of the right globe.
1:58
When one has low density in the anterior
2:01
chamber or elsewhere around the globe,
2:04
one has to worry about the potential
2:07
for wood foreign bodies.
2:09
Now, wood can be more dense than CSF or soft tissue,
2:14
particularly if there is leaded wood,
2:18
versus less dense when we have soft wood,
2:21
like balsa wood, for example.
2:24
Foreign bodies associated with the globe is very important
2:29
to identify because it can be a source of infection.
2:33
And globe infection, endophthalmitis, has a natural course
2:39
which can lead to something called phthisis bulbi,
2:43
where the globe shrinks down and calcifies due
2:47
to the chronic infection. In this situation,
2:50
I would report on the anterior hyphema,
2:54
the globe rupture secondary to a foreign body,
2:59
which is likely to represent wood foreign body as opposed
3:04
to metallic foreign body because of the low density.
3:08
And I would include
3:10
the vitreous hemorrhage in this patient.
