The image belongs to a 35 year old woman with pain in the left eye. Acanthamoeba spp. cyts can be seen when we examine the contact lenses solution (optical microscope 100x with methylene blue staining). On a slide, a homogenous suspension is made between contact lenses solution and methylene blue. This method allows you to know the protozoa, based on morphological characteristics. It can be seen Acanthamoeba spp. cyst with a double cell wall. The outside wall is called ectocisto, thin and wavy, and inside one is called endocisto, rounded.
