Figure 3. Role of the K channel in retinal arteriolar dilation in response to unoprostone isopropyl (UI). The K channel in retinal arteriolar
dilation in response to unoprostone isopropyl (UI), tetraethylammonium (TEA; 10 mM, n = 4), and iberiotoxin (0.1 µM, n = 4)
reduces vasodilation in response to UI. *p<0.05 versus control.
