A program for detection and follow-up of glaucoma aimed at individuals living in underserved urban communities, including senior housing residences, showed success in improving adherence to monitoring appointments and therapy.

In 2012, the Willis Eye Hospital Glaucoma Research Center launched the Philadelphia Glaucoma Detection and Treatment Project, offering free glaucoma detection exams, regular monitoring, medications, laser therapy and surgery when needed. Retrospective analysis of 531 participants – 91 of whom had glaucoma, 154 who had anatomic narrow angle and 286 who were glaucoma suspects – investigated adherence to follow-up exam appointments.
