I want to make a quick point about non-accidental
0:04
trauma or shaken baby syndrome or child abuse,
0:09
and that is that retinal hemorrhages are one of the
0:13
most common manifestations of
0:15
injury in non-accidental trauma.
0:19
We're used to looking for subdural hematomas in
0:24
patients who have non-accidental trauma.
0:28
And we want to look at subdural
0:30
hematomas of different ages.
0:31
So this one would be our chronic one that is
0:33
low density. This one is a hyperacute one,
0:37
which is of the higher density. Hemorrhages
0:40
along the interhemispheric
0:41
fissure is also very characteristic of
0:44
non-accidental trauma. However,
0:46
it's been reported that 70% to 90% of children who have
0:50
suffered through shaken baby syndrome also have little
0:53
areas of retinal hemorrhage that can be
0:56
seen on ocular imaging. So this maybe,
1:00
in some cases,
1:00
the only manifestation of the childhood injury.
1:04
But it also may help settle the case as to whether or not
1:09
this could be secondary to intentional
1:13
trauma to the child.
1:14
Here is what the hemorrhages look like on the
1:18
ophthalmologic funduscopic examination.
1:21
It's these little areas of blood products which
1:25
you see in multiple locations,
1:27
which represents little shearing
1:29
injuries of the retina.
1:32
And funduscopic evaluation is definitely
1:34
more sensitive than our CT scan,
1:36
but occasionally we will see those areas of retinal
1:39
hemorrhage and/or retinal detachment that
1:42
are associated with non-accidental trauma.
1:45
So after you've looked at the brain,
1:47
after you've looked at the musculoskeletal system and
1:51
look for the various types of fractures,
1:53
do come back to the brain,
1:55
take out those thin section orbital images
1:58
and look for those little areas
2:00
of potential retinal hemorrhage
2:03
that might be additional evidence
2:05
of non accidental trauma.
