Background: We sought to investigate visual function, primarily, and structural changes in retinal ganglion cells, secondarily, in patients with major depressive disorder.
Methods: A total of 50 normal participants and 49 patients with major depressive disorder were included in this cross-sectional study. The participants underwent 24-2 standard automated perimetry and spectral-domain optical coherence tomography.
Results: The pattern standard deviation (PSD) in the visual field test was higher in the major depressive disorder patients than in the normal control subjects ( = 0.017). The patients with major depressive disorder showed reduced minimum ganglion cell-inner plexiform layer (GCIPL) thickness relative to the normal control participants ( = 0.015). The average score on the Hamilton Depression Rating scale showed a significant correlation with the PSD, minimum GCIPL thickness, and inferior GCIPL thickness (r = 0.265, = 0.009; r = -0.239, = 0.017; and r = -0.204, = 0.043, respectively). The multivariate analysis of factors associated with PSD showed old age and a high Hamilton Depression Rating score to be relevant ( = 0.002 and 0.028, respectively).
Conclusions: Visual function was decreased and the GCIPL thickness was reduced in major depressive disorder patients. The retinal neurodegenerative process in depression might be considered in patients with depression.

Background: Bipolar disorder (BD) has been associated with impaired cellular resilience. Recent studies have shown abnormalities in the unfolded protein response (UPR) in BD. The UPR is the cellular response to endoplasmic reticulum (ER) stress.

Changes in astrocyte function contribute to depressive-like behaviors. However, while neuronal mechanisms driving MDD have been studied in some detail, molecular mechanisms by which astrocytes promote depression have not been extensively explored.

Background: Recurrent symptom-relevant negative autobiographical memories are common in patients with emotional disorders such as anxiety and depression, even among those without a trauma-related diagnosis. Recurrent negative autobiographical memories may also contribute to distress in non-clinical populations.
Methods: To examine the prevalence of recurrent negative autobiographical memories and associated psychological features, we recruited a student sample ( = 101) and a treatment-seeking sample of patients with emotional disorders ( = 123).

Astrocytes are the primary cell type in the central nervous system, responsible for maintaining the stability of the brain's internal environment and supporting neuronal functions. Researches have demonstrated the close relationship between astrocytes and the pathophysiology and etiology of major depressive disorder. However, the regulatory mechanisms of astrocytes during depression remain unclear.
