Cellular fluorescein hyperfluorescence is dynamin-dependent and increased by Tetronic 1107 treatment

Sodium fluorescein (‘fluorescein’) staining of the ocular surface is frequently an indicator of compromised ocular health, and increases in the presence of certain contact lens multi-purpose solutions (MPS), a phenomenon known as solution induced corneal staining (SICS). The mechanism(s) underpinning fluorescein hyperfluorescence are uncertain, though may reflect increased cellular uptake of fluorescein by corneal epithelial cells. We have...
