Purpose This study was designed to raise awareness of the materials, devices, and Internet resources available to improve adherence to use of medications for the treatment of glaucoma and to review new devices under development. Methods A review of current indexed literature and Internet resources was conducted. Results A variety of educational brochures, pamphlets, and fact sheets promoting adherence to ocular hypotensive medications are available through multiple organizations and are easily accessed and ordered on the Internet. Video and Web-based patient educational tools have been designed to support patient adherence to glaucoma management plans and promote open dialogue between patients and providers. Reminder and recall systems that integrate with office software can be sent to cell phones as well as e-mails and personal digital assistant (PDAs), alerting patients to upcoming appointments and reminding them to instill their drops. Bottle devices with dosing support (timers with audible and visual signals and dispensing aids) and electronic monitoring have been shown to promote adherence. New products currently under development to improve the delivery of medications include nanoparticles, punctal plugs, and contact lenses that release glaucoma medications. Conclusions Many educational materials, services, Internet resources, and devices are available to optometrists to encourage patient adherence to glaucoma treatment and management.
