Amnesia's Dream: Hendra Virus And Blur Vision

Hendra virus from the Pteropus fruit-eating bats, commonly known as flying foxes,

and

can infect horses and human.

In the eyes it is deadly as it can cause viral meningitis. And in general, nasal infection,

combined,

Brown pus means bleeding when the virus was introduced. Breaking the membrane behind the eye orbit might be intended to ensure viral meningitis.

Good luck.
