OBJECTIVE: To evaluate the Heidelberg Retina Tomograph II (HRTII; Heidelberg Engineering, Heidelberg, Germany) as a screening tool for open-angle glaucoma (OAG) in an older population. DESIGN: Population-based, cross-sectional study. PARTICIPANTS: Participants from the 10-year follow-up Blue Mountains Eye Study (n = 1952; 75.6% of survivors). METHODS: Participants underwent optic nerve head imaging performed using the HRTII; OAG was diagnosed independently from optic disc photographs and Humphrey 24-2 visual fields. MAIN OUTCOME MEASURES: The Moorfields Regression Analysis (MRA) was applied to scans using the default results of "normal," borderline," and "outside normal limits." Outcome classification was at the person level and used data from both eyes. RESULTS: Mean age was 73.7 years. The HRT scans could be acquired in 1644 participants, 95.9% of those fully examined; 87.4% of scans having a topography standard deviation (TSD)
