Another group investigated the effect of every-other-day fasting (EODF) in EAAC1-/- (excitatory amino acid carrier 1-deficient) normal-tension glaucoma mouse model,27 and the results suggested that RGC death and retinal degeneration were suppressed in the EODF group, independent of IOP measurements. The gene discussed is SLC1A1; the disease is low tension glaucoma.
