Short‐Term Daily Oral Administration of Cannabidiol Does Not Impact Rebound Tonometry Intraocular Pressure or Schirmer Tear Test Values in Healthy Adult Horses

Abstract Objective: To assess the effect of orally administered cannabidiol (CBD) on TonoVet measured intraocular pressure (IOP) and Schirmer tear test I (STT) in horses. Animal Studied: Horse. Procedure: This was a masked, randomized, balanced cross‐over study of six healthy adult horses. Horses were randomly assigned and received 3 mg/kg CBD in sesame oil or volume matched placebo by mouth once daily for three days. Baseline and daily 4‐, 12‐, and 24‐h post treatment IOPs were measured in triplicate without
