(a) The overall relative abundance of Actinobacteriota was significantly greater in Normal than IBK eyes (p = 0.0040). Three species within Actinobacteriota including Corynebacterium stationis (p = 0.0061) (b) and Corynebacterium variabile (p = 0.0016) (c) were noted to present at higher relative abundance in Normal eyes than IBK eyes. A third species within Actinobacteriota, Rothia nasimurium (d), was present at higher relative abundance in IBK eyes (p < 0.0001). Student’s t tests or ANOVA tests were used to evaluate abundance
