Endophthalmitis or inflammation of the globe can occur
0:06
outside the setting of trauma and foreign bodies.
0:10
Usually, this is secondary to skin infections,
0:14
sometimes affectionately known as Zit Popper syndrome,
0:19
and that is if one has an infection of the skin related to
0:24
acne or other scratches, or perforations of the skin,
0:31
it may extend to the globe.
0:34
Endophthalmitis, as I described earlier,
0:38
is a serious infection and is treated aggressively by the
0:42
clinicians because of this phenomenon in which one
0:45
can have an autoimmune attack on one's own globe,
0:49
leading to Phthisis bulbi.
0:52
Phthisis bulbi is the end stage of either
0:56
trauma or infection to the globe,
0:59
in which the globe is calcified, shrunken, and the patient
1:05
is blind. That autoimmune reaction to the globe may
1:16
was not traumatized or otherwise infected.
1:21
Another inflammatory condition that occurs and
1:24
causes an endophthalmitis is pseudotumor,
1:28
also known as idiopathic orbital inflammation,
1:32
or nonspecific idiopathic orbital disease. In this case,
1:38
one sees asymmetrical enhancement along the posterior
1:43
aspect of the left globe, as well as
1:47
in the adjacent fat soft tissues.
1:52
This would be called scleral or episcleritis.
1:56
Pseudotumor or idiopathic orbital inflammation can
1:59
occur in any part of the globe.
2:03
In this case, one also sees that the sclera anteriorly
2:08
shows greater enhancement than on
2:12
the contralateral normal side.
2:19
Pseudotumor of the orbit is treated with corticosteroids
2:24
as the first line of treatment,
2:26
and therefore, it is important to make
2:28
the distinction between an infection,
2:31
which should not be treated with steroids,
2:33
and this idiopathic orbital inflammation,
2:36
which is treated with steroids.
2:38
Both of these types of diseases can cause
2:43
pain and tearing of the eye.
2:45
However, the infectious etiologies may be associated with
2:49
fever and usually have a nidus that is leading
2:54
to the inflammation of the globe.
