Let's discuss the membranes of the globe in
0:03
a little bit more detail.
0:05
As I mentioned,
0:06
the sclera is the most outer portion of the membranes and
0:11
becomes continuous with the cornea far anteriorly.
0:17
The next membrane to talk about is the choroid.
0:21
As I mentioned,
0:22
the choroid goes far anterior and communicates with the
0:26
ciliary body at the level of the lens of the eye.
0:34
The third membrane is the retina.
0:36
The retina is seen in yellow here
0:40
and as I mentioned previously,
0:42
it ends at an area called the ora serrata at that junction
0:48
with the 10:00 and 02:00 on the globe and does
0:52
not go as far anteriorly as the choroid.
0:55
This helps you in identifying retinal detachments which
0:59
stop at 10:00 and 02:00 from choroidal detachments
1:03
which will go all the way up to the lens.
1:06
These detachments occur between the different layers
1:10
of the membranes, as you can see here.
1:14
This is the vitreous
1:17
compartment and you can have a collection which occurs
1:23
between the edge of the vitreous and the retina
1:27
and this is the post-hyaloid or subhyaloid space.
1:33
You may also have a collection between the sensory and
1:39
retinal pigment epithelium of the retina
1:44
which would be in the subretinal space.
1:49
There is also a space between the choroid
1:54
and the sclera which is termed the suprachoroidal space.
2:01
And finally, although it's unusual to see,
2:04
you can have a collection that is between the choroid
2:09
and the retina in the subchoroidal space.
