Structural data from various devices were converted into a Structural Metascore (SMS), and the Visual Field Index (VFI) was used as the functional parameter. Robust linear regression was applied to each eye\u2019s SMS and VFI over time. Eyes were categorised by baseline mean deviation (MD) into preperimetric (MD \u22650 dB), mild (\u22126 &lt; MD &lt; 0 dB), moderate (\u221212 \u2264 MD \u2264 \u22126 dB) or severe (MD &lt;\u221212 dB).

Structural and functional slopes were more correlated in earlier stages. Progression classifications were: both structural and functional (6%), structural-only (13%), functional-only (11%) and stable (70%). Functional-only progression was more common in moderate and severe glaucoma, while structural-only progression predominated in earlier stages. The SMS approach achieved 8.9% prediction error compared with 34.1% for single-device methods.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>The 3D trajectory model visualises distinct progression patterns, with structural changes preceding functional decline in earlier stages and functional-only progression dominating in advanced stages.
