Retinal and choroidal vascular density alterations in patients with schizophrenia: assessment via optical coherence tomography angiography
To evaluate the association between retinal and choroidal vascular density with schizophrenia (SCZ) using optical coherence tomography angiography (OCTA), hypothesizing that microvascular abnormalities may reflect systemic or neurovascular dysfunction associated with SCZ pathogenesis.
Key Findings:
Patients with SCZ exhibit significant thinning of the retinal nerve fiber layer and reduced choroidal thickness compared to healthy controls (p-value).
Retinal microvascular abnormalities correlate with the severity of psychotic symptoms and cognitive impairment (correlation coefficient).
Choroidal vascular density alterations may be linked to the pathophysiological mechanisms of SCZ.
Interpretation:
The study suggests that retinal and choroidal vascular changes may serve as potential biomarkers for SCZ, reflecting underlying vascular dysfunction associated with the disorder, which could influence future research and clinical practices.
Limitations:
The study's cross-sectional design limits causal inferences and may introduce biases.
The sample size and demographic diversity may affect the generalizability of findings.
Conclusion:
Alterations in retinal and choroidal vascular density in SCZ patients could provide insights into the vascular pathophysiology of the disorder and serve as non-invasive monitoring tools, emphasizing the need for further research in this area.
