What the study found
The study found that people with anxiety disorders showed distinct eye movement patterns compared with people with depressive disorders and healthy controls. These patterns were called hyper-scanning, meaning increased visual scanning during free viewing, and hyper-pursuit, meaning stronger-than-usual smooth tracking of moving targets.
Why the authors say this matters
The authors conclude that these eye movement patterns may serve as measurable behavioural markers for distinguishing anxiety disorders from other affective disorders. The findings also suggest that eye-tracking could be a promising way to study mechanisms such as vigilance and prediction in anxiety.
What the researchers tested
The researchers recorded eye movements in 91 patients with anxiety disorders, 118 with depressive disorders, and 98 healthy controls. Participants completed free viewing of neutral stimuli, a smooth-pursuit task, and a fixation-stability task, and the team used principal component analysis to identify latent eye movement dimensions and machine learning models to test classification performance.
What worked and what didn't
Compared with both depressive disorder patients and healthy controls, the anxiety group showed increased saccade frequency and path length during free viewing, along with increased velocity gain, fewer intrusive saccades, and more catch-up saccades during smooth pursuit. Principal component analysis identified six latent components, and among them active visual exploration, pupillary arousal, and smooth-pursuit control showed robust group differences. The machine learning models achieved area under the receiver operating characteristic curve values of 0.82 for anxiety versus healthy controls, 0.83 for depression versus healthy controls, and 0.61 for anxiety versus depression.

Key points
- People with anxiety disorders showed hyper-scanning during free viewing and hyper-pursuit during smooth pursuit.
- The anxiety group differed from both depressed patients and healthy controls on several eye movement measures.
- Six latent eye movement components were identified, including active visual exploration, pupillary arousal, and smooth-pursuit control.
- Classification performance was stronger for anxiety versus healthy controls and depression versus healthy controls than for anxiety versus depression.
- The authors suggest eye-tracking may help differentiate affective disorders.
