Figure 2. The effect of unilateral electrical stimulation of the ARC on intraocular pressure for the ipsilateral eye on electrical (a) and antagonist (b) effects, and for the contralateral eye on electrical (c) and in antagonist (d) effects.

Figure 2

The error-bar (mean ± SE) of each group was located at time points of 0, 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55 and 60 minutes, respectively. A slight separation was made for error-bars at the same time points to avoid overlapping. I, Control group; II-1, electrical stimulation group; II-2, ARC naloxone+electrical stimulation group; II-3, ARC saline+electrical stimulation group; II-4, subconjunctival naloxone+electrical stimulation group; II-5, subconjunctival saline+electrical stimulation group.
