Paired baseline ONSD and brain imaging were performed in 63 participants. Higher baseline ONSD was associated with more severe disease and abnormal brain imaging (abnormal imaging 0.55 cm vs 0.50 cm normal imaging, P = .01). Baseline median ONSD was significantly higher in participants who died by 3 months (0.56 cm [15\/72]) versus participants who survived by 3 months (0.52 cm [57\/72]) (P = .02). Median ONSD was higher at all follow-up times in participants who died by 3 months.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusions<\/jats:title>\n                  <jats:p>Higher ONSD was associated with increased disease severity, brain imaging abnormalities, and increased death by 3 months.
