Case of the Week 730

 This week's case is generously donated by Idzi Potters and the Institute of Tropical Medicine, Antwerp.

The following were seen in used contact lens solution from a young woman with complaints of eye pain and blurry vision. The first two images are taken with light microscopy, and the third with phase-contrast microscopy. What is your diagnosis? Please describe the forms you are seeing.

Wow, pictures perfect rendition of the “thorny” amoeba and its polygonal cyst. Thank you Idzi for the classic case.
