Changes in Anterior Chamber Parameters Measured by Pentacam in Coronavirus Disease 2019 Infection: A Longitudinal Study

Table 1

Pentacam parameter mean values in different visits and comparison between different visits. SD: standard deviation; K_m front: keratometry mean front; K_m back: keratometry mean back; CTT: cornea thinnest thickness; K_max front: keratometry maximum front; CV: cornea volume; ACV: anterior chamber volume; ACD: anterior chamber depth.
