Vision 2020: where are we?

Abstract

To describe the VISION 2020: The Right to Sight, global initiative for the elimination of avoidable blindness, the contribution of glaucoma to the magnitude of global blindness and priorities going forward. Although the target of the World Health Organization's Global Action Plan (2014-2019) has not been met in terms of 25% reduction in avoidable blindness, there is evidence that the contribution of glaucoma to blindness and vision impairment is reducing. Yet this focus on a threshold of visual acuity by which to measure prevalence underestimates the true burden of glaucoma. Recent population-based studies demonstrate the scale of the unmet need. Scaling up of integrated people-centered eye care, by embedding glaucoma detection and care pathways in health systems with a strong focus on primary healthcare, is necessary. Solutions include reinforcing existing pathways while emphasizing high-quality glaucoma care, in addition to novel solutions such as self-testing, digital portable technology, artificial intelligence, and multilevel care pathways that extend to the most underserved parts of the global community.
