Influence of Cannabidiol Use on Visual Function and Optical Quality: A Randomized Controlled Trial.

ABSTRACT:

Purpose

To study the influence of different concentrations of vaporized cannabidiol (CBD; 0%, 15%, and 30%) on visual function and optical quality.

Methods

A randomized, crossover, double-blind, placebo-controlled, experimental study was conducted. A total of 30 participants with a mean age of 26.0 ± 6.3 years completed the study. Placebo (0 mg of CBD), 15% (16 mg of CBD), and 30% (32 mg of CBD) concentrations of CBD were employed. Visual function was evaluated through various tests, including pupil size, static and dynamic visual acuity, contrast sensitivity, dot motion detection, visual disturbance index (VDI), and stereoacuity. Optical quality was assessed by log(s), modulation transfer function (MTF) cutoff, objective scattering index (OSI), and Strehl ratio. Self-percei
