Objective: To investigate the effects 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 received 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.  Optical coherence  tomography  scannings  were  performed  by  the  same  physician and  all subfoveal CT measurements were taken manually 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 7 measurement periods were not statistically significant in the study and control groups (p=0,417,  p=0,856; respectively).



Conclusion: The ED in our study didn’t change subfoveal choroidal thickness significantly in spite of the caffein content. This may be due to the interactions of caffein with other ingredients of the ED.
