What is Choroidal thickness changes in healthcare professionals wearing surgical masks or FFP2 masks: Pilot study about?

## Purpose: To evaluate the choroidal thickness (ct) with enhanced depth-imaging optical coherence tomography (edi-oct) in healthcare professionals using surgical masks or ffp2 (n95) masks. ## Methods: We included the 120 eyes of 120 healthy volunteers who were using a surgical mask (group 1) or ffp2 mask (group 2) in the study. spectral domain (sd) oct was used to measure ct. edi-oct was used to measure subfoveal and perifoveal ct. points 1500 μm nasal (c) and temporal (c) to the foveal center were used to measure perifoveal ct. oxygen saturation and heart rate were measured with a pulse oximeter. all measurements were performed at 8:30, before wearing the mask, and at 12:30, when the mask was removed for the lunch break. ## Results: Of a total of 120 subjects, group 1 consisted of 60 subjects (mean age 38.50±8.60 (range 24-44) years) and group 2 also consisted of 60 subjects (mean age 36.60±6.53 (range 26-45) years). although not statistically significant, ct was seen to have increased at 3 measurement points in group 1 after using the mask for 4 h: subfoveal ct (c) (p = 0.545), c (p = 0.080), and c (p = 0.251)). in group 2, the increase in c (p = 0.001) was statistically signifi
