Abstract

To find out the optimal temperature of infusion fluid during vitrectomy, five rabbit eyes were infused with body temperature (37C) Balanced Salt Solution Plus (BSS Plus, Alcon Laboratories) and the other five eyes with room temperature (22C) BSS Plus. We recorded the ERGs before operation and 2 days, 7 days and 28 days after operation and each recording was plotted on paper with automatically measured amplitude. The a-wave amplitude, b-wave amplitude and b/a ratio showed no significant difference between 22C and 37C groups before operation and 2 days, 7 days and 28 days after operation. The a-wave amplitudes were decreased, b/a ratios were increased and b-wave amplitudes was not changed after operation in both 22C and 37C group. We suggest that there is no difference in the effects of infusion fluid to retinal function whether we use room temperature or body temperature infusion fluid.
