Elevated pressure alters Na⁺ and K⁺ homeostasis in Müller glia. Primary, purified cultures of Müller glia were exposed to ambient (Amb) or elevated (Elev) pressure for 4 or 48 h. A: box plots of the concentration of K⁺ ions in the culture media of Müller glia at each condition. One-way ANOVA with pairwise comparison by Tukey’s method was used to analyze statistical significance. B: box plots of the concentration of Na⁺ ions in the culture media of Müller glia compared between each condition. One-way ANOVA with pairwise comparison by Dunn’s method was used to analyze statistical significance. n(Amb 4 h) = 5 wells; n(Elev 4 h) = 4; n(Amb 48 h) = 12; n(Elev 48 h) = 12. **P < 0.001.
