Acanthamoeba keratitis - External and Internal Eye
Patients with AK will present complaining of ocular pain, light sensitivity, red eye, blepharospasm, excessive tearing, and possibly reduced vision. Often times, especially in early disease, patients' symptoms will be more significant than what is seen on physical exam. The findings in AK can look very similar to herpetic keratitis, and it is not uncommon for patients to be first treated unsuccessfully with antiviral and/or steroid medications before correct diagnosis of AK is made.
