Abstract

The present study aimed to investigate functional networks underlying brain‑activity alterations in patients with acute unilateral open globe injury (OGI) and associations with their clinical features using the voxel‑wise degree centrality (DC) method. In total, 18 patients with acute OGI (16 males and 2 females), and 18 healthy subjects (16 males and 2 females), closely matched in age, sex and education, participated in the present study. Each subject underwent a resting‑state functional magnetic resonance imaging scan. The DC method was used to assess local features of spontaneous brain activity. Receiver operating characteristic curve analysis was used to distinguish OGIs from healthy controls (HCs). Correlation analysis was used to examine the association between the observed mean DC values of different brain areas and behavioral performance. Compared with HCs, patients with acute unilateral OGI had significantly increased DC values in the bilateral primary visual cortex (V1/V2) and left precuneus (PCUN), and significantly decreased DC values in the right insula, left insula, right inferior parietal lobule (IPL)/supramarginal gyrus (SMG), IPL/SMG, right supplementary motor area and right postcentral gyrus. Additionally, in the acute OGI group, it was observed that the duration of OGI was negatively correlated with the DC signal value of the bilateral V1/V2 (r=‑0.581; P=0.011) and left PCUN (r=‑0.508; P=0.031). Acute OGI led to brain functional network dysfunction in a number of brain regions, which may indicate impairment of the visual cortex and other vision‑associated brain regions in OGI.
