A test to differentiate between people who are unlikely to develop glaucoma and those at risk for the disease could be clinically useful. Ibopamine, when administered topically, temporarily increases aqueous production. Normal eyes with healthy trabecular meshwork show no significant change in intraocular pressure (IOP<\/jats:styled-content>) following an ibopamine challenge; however, those with glaucoma demonstrate elevated IOP<\/jats:styled-content>.<\/jats:p><\/jats:sec>Design<\/jats:title>The study was designed as a prospective case\u2013control study in a tertiary hospital.<\/jats:p><\/jats:sec>Participants<\/jats:title>Patients were recruited consecutively as they presented to glaucoma clinics at F<\/jats:styled-content>linders M<\/jats:styled-content>edical C<\/jats:styled-content>entre (n<\/jats:italic>\u2009=\u200939); the sample included 18 glaucoma suspects and 21 patients with glaucoma.
