Description:Aqueous humor samples for metabolomics experiment were generated in the following manner: Eight adult male white rabbits were given seven days to acclimate to their environment. On day eight, an Ahmed Glaucoma Valve was implanted into the left eye of every rabbit. The un-operated right eye served as control. One rabbit was lost during the course of the study. After adequate anesthesia, aqueous humor samples were taken from both eyes of each rabbit before surgery (A samples), and at 27 (B samples), 52 (C samples) and 153 days (IV samples) after surgery.
