Acanthamoeba kerititis?

Pretty nasty if it gets in the brain...

I would go with Acanthamoeba. The treatment for this is quite arduous, as I remember. Eye drops q 4 hours for days, if not weeks.

Agree with Acanthamoeba. Nice double-walled cysts in tissue and culture and amoebas with acanthopodia in culture.
