In a series of Caucasian patients over the age of 40 years, the number of individuals unable to recognize the bitter taste of phenylthiourea (8.1 mg/100 ml) was found to be 28 percent in a "normal" eye clinic population (446 individuals), 17 percent in a series of 155 patients with angleclosure glaucoma, and 53 percent in 211 patients with primary open-angle glaucoma.
