KP (keratic precipitates) on the back of the cornea (Video)

In this video you can see particles stuck to the back surface of the cornea. These are KP (keratic precipitates) which are clusters of inflammatory cells that tend to congregate and stick to the endothelium during times of AC inflammation (uveitis).

As you can see in this video, the KP spots are visible on the back surface of the corneal light-beam, and can also be seen when retroilluminating the iris behind.

Keratic Precipitates
This photo shows KP or keratic precipitates on the inner surface of the cornea. This occurs with long-standing uveitis or other ocular inflammation.
KP on inner cornea
These KP are sometimes difficult to see without using the slit-beam of light, like in this photo. You can see the opacities directly in the light, and also by retroillumination from the iris.
