Demographic, clinical and multimodal imaging data were collected and compared. Univariable and multivariable regression analyses were performed to assess risk factors.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Among 69 eyes, 16 were classified as RCH-MS, 33 as RCH-ME and 20 as RCH-MT. Compared with RCH-MS, RCH-ME and RCH-MT exhibited significantly worse visual acuity. Multivariable analysis revealed that RCH-MT was associated with greater tumour-to-foveola distance (OR 1.347, 95%\u2009CI 1.024 to 1.771) and higher prevalence of fibrovascular proliferation overlying the RCH (OR 14.371, 95% CI 1.622 to 127.301). Feeding artery dilation was significantly associated with RCH-ME (OR 17.392, 95% CI 2.121 to 142.627) and worse visual acuity (\u03b2=0.374, 95% CI 0.023 to 0.724). Feeding artery beading was inversely associated with RCH-ME (OR 0.057, 95% CI 0.006 to 0.552) and correlated with better visual outcome (\u03b2=\u20130.472, 95% CI \u20130.894 to \u20130.051).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>The macular status of large solitary peripheral RCHs is influenced by tumour location, fibrovascular proliferation and feeding artery characteristics.
