This week's case is in honor of the third annual Contact Lens Health Week (August 22-26). Contact lenses were received from a young adult male with bilateral conjunctivitis, photophobia and eye pain. These symptoms began shortly after he had been swimming in a freshwater lake while wearing his contact lenses. The contact lenses were plated for bacterial, mycobacterial, fungal and free-living amebic cultures, and fluid from the contact cases was sent to the cytology lab where it was made into a cell block. Here are photographs from the H&E-stained cell block specimen.
