Assessment of viable lens-associated PA. Contact lenses were incubated for 24 hours at a PA:PMN ratio of 1:1. There was significant increase in viable and nonviable PA after exposure to either PMA-stimulated neutrophils or freeze–thaw neutrophils cell lysates compared with PA alone. (A) PA alone; (B) PA with PMA-stimulated neutrophils; (C) PA with freeze–thaw (F-T) neutrophil cell lysates. Scale: 14.58 μm. (D) Zoomed image of PA incubated in the presence of PMA-stimulated neutrophils showing PA adherent to dead cells (arrow). Scale: 9.7 μm.
