Abstract

Objective: This study aims to investigate the effects of consumption of energy drink (ED) on subfoveal choroidal thickness (CT) using enhanced depth imaging spectral domain optical coherence tomography (EDI-OCT).
Methods: In this study, 40 healthy volunteers who consumed 250 mL ED and 40 healthy subjects who consumed 250 mL water were enrolled. All volunteers underwent EDI-OCT scanning for subfoveal CT measurement at baseline and following time periods after ED or spring water consumption. The OCT scannings were performed by the same physician, and all subfoveal CT measurements were manually taken by two independent masked physicians. All subfoveal CT measurements for both groups were analyzed by repeated measure analysis.
Results: Our results showed no significant difference in baseline and following subfoveal CT measurements between the groups (p>0.05, for all). The difference in mean values among the following seven measurement periods was not statistically significant in the study and control groups (p=0.417 and p=0.856, respectively).
Conclusion: The ED in our study did not significantly change subfoveal CT in spite of the caffein content. This may be because of the interactions of caffein with other ingredients of the ED.
