Whereas higher drusen volume was associated with the presence and volume of HRF, it was inversely correlated with SDD presence. Thickness measurements of the EZ and ONL demonstrate outer retinal thinning, indicating photoreceptor compromise in iAMD, more pronounced in eyes showing atrophic features such as iRORA or EZLHT.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>This work combines expert grader readings with AI-based image analyses, applied on the largest prospectively, densely OCT-imaged cohort of iAMD reported on so far. The results show feature distribution comparable to previous reports. They substantially contribute to the comprehensive morphological characterisation of iAMD. This data is relevant for the interpretation of longitudinal data, refining inclusion criteria for future clinical trials and for providing a reference to other trials in the field.<\/jats:p>\n
