Objectives: Studies of schizophrenia endophenotypes may help clinicians better understand the etiopathogenesis and treatment of this mental disorder. The aim of the study was to determine if retinal arteriolar or venular abnormalities are an endophenotype of schizophrenia.

Design: We performed a one-time cross-sectional study.

The review is a summary of structural and functional changes in the human retina observed in patients with schizophrenia. The main focus is on the potential of these changes to serve as schizophrenia-specific biomarkers accessible to clinicians.
