Methods This prospective, non-interventional, natural-history ‘Directional Spread in Geographic-Atrophy’ study was conducted at the University Eye Hospital in Bonn, enrolling 82 patients with bilateral GA. Parameters such as GA location (assessed by the Early Treatment Diabetic Retinopathy Study grid), best-corrected visual acuity (BCVA), low-luminance visual acuity (LLVA), reading acuity, and speed were examined. The association between these parameters and VRQoL, as gauged using the National Eye Institute Visual Function Questionnaire 25 (NEI VFQ-25), was analyzed through least absolute shrinkage and selection operator with linear mixed-effects models. Results The average total GA area observed was 2.9 ± 1.2 mm 2 (better eye) and 3.1 ± 1.3 mm 2 (worse eye). The VRQoL scores for distance and near activities were most associated with the inner lower and inner left subfields of the better eye. For foveal-sparing patients, the LLVA of the better eye was the predominant determinate impacting all VRQoL scales. Conclusion GA location, specifically the inner lower and inner left subfields of the better eye, has a notable effect on VRQoL in GA patients. LLVA stands out as especially vital in foveal-sparing patients, underscoring the importance for clinicians to incorporate considerations of GA location and functional parameters into their risk-benefit assessments for emerging treatments. Key messenges What is already known on this topic Despite recent therapeutic advancements, the relationship between GA markers and VRQoL remains unclear. What this study adds This research reveals the distinct value of specific structural and functional GA markers, notably the inner left and inner lower subfields, and LLVA, in relation to VRQoL in GA patients. How this study might affect research, practice, or policy Understanding these structural and functional markers will guide clinicians in personalized treatment decisions and encourage further research into more tailored therapeutic interventions.","journal":"medRxiv","year":2023,"id":400884,"datarank":0.0,"base_score":0.0,"endowment":0.0,"self_citation_contribution":0.0,"citation_network_contribution":0.0,"self_endowment_contribution":0.0,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":1,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.8518,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2023-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":1177587,"name":"Eliza Broadbent","orcid":"0000-0003-1202-0474","position":1,"is_corresponding":false},{"id":1178009,"name":"Philipp T.
