Representative intensity-response curves are provided in Supplementary Fig
Specifically, those in the supplement group saw a 37.3% improvement in visual field mean deficit (0.49-decibel increase (-1.8 to -1.13 decibels)) compared to a minimal worsening in the placebo group (0.01-decibel decrease) ( p = 0.023)
They work by binding and activating the ghrelin receptor, which is involved in regulating appetite, energy homeostasis, and GH secretion
