Retinal and choroidal vascular density alterations in patients with schizophrenia: assessment via optical coherence tomography angiography

Category	Detail
Condition	Schizophrenia (SCZ)
Key Mechanisms	Microvascular dysfunction including retinal and choroidal vascular density alterations potentially linked to neurovascular pathology in SCZ
Target Population	Adults aged 18–65 years diagnosed with schizophrenia, drug-naïve or off antipsychotics for ≥3 months
Care Setting	Clinical psychiatric and ophthalmologic evaluation settings using non-invasive imaging

Schizophrenia is associated with microvascular abnormalities including reduced retinal and choroidal vascular density.
The retina and brain share embryological and vascular similarities, making retinal imaging a valuable non-invasive biomarker for CNS disorders.
Optical coherence tomography angiography (OCTA) enables high-resolution, contrast-free visualization of retinal and choroidal microvasculature.

Use DSM-5 criteria for schizophrenia diagnosis confirmed by at least two attending physicians.
Exclude other psychiatric disorders and systemic diseases to isolate SCZ-related vascular changes.
Employ OCTA imaging to assess retinal and choroidal vascular density as potential biomarkers.

Consider vascular dysfunction as a component in SCZ pathophysiology when planning comprehensive care.
Monitor ocular microvascular changes as part of disease progression assessment.

Utilize OCTA for non-invasive, repeatable assessment of retinal and choroidal vascular density.
Correlate vascular imaging findings with clinical symptom severity and cognitive function.

Be aware of confounding systemic conditions (e.g., hypertension, diabetes) that affect choroidal blood flow.
Recognize that microvascular changes may reflect broader neurovascular pathology impacting disease course.

Drug-naïve or medication-free schizophrenia patients aged 18–65 years.

Vascular abnormalities identified via OCTA may inform adjunctive therapeutic strategies targeting neurovascular health.

Confirm schizophrenia diagnosis rigorously using DSM-5 and multidisciplinary clinical evaluation.
Exclude comorbid psychiatric and systemic diseases to ensure specificity of vascular findings.
Incorporate OCTA imaging into routine assessment for early detection of microvascular changes.
Interpret retinal and choroidal vascular density alterations in the context of overall neurovascular health.
Use retinal biomarkers to complement neuroimaging and clinical symptom monitoring.
