• Thirty-three ocular, systemic, and laboratory variables were used in a discriminant analysis to separate 219 patients suffering from chronic openangle glaucoma from 100 people who did not have the disease. The analysis used seven of the variables to separate 93% of the patients correctly. Without intraocular pressure, a 90% separation was obtained.
