Abstract
Background: Schizophrenia is a detrimental neurodevelopmental disorder that affects nearly 1 % of the population worldwide. Although schizophrenia ranks among the leading causes of global disease-related disability, definitive investigations do not exist for its diagnosis at present. Since the retina is derived from the same neural layer that the brain develops from, OCT imaging of retina can provide valuable information regarding underlying pathology of schizophrenia. Objectives: This review aims at describing the potential relevance of OCT studies 1) in understanding current insights into retinal structural changes in schizophrenia 2) in understanding the relationship between retinal structural alterations and disease progression and chronicity 3) and to determine the potential role of retinal changes as biomarkers of schizophrenia. Methodology: A comprehensive search of databases such as PubMed, Google Scholar and Medline was conducted using the keywords: schizophrenia, retina, OCT and RNFL changes. Relevant articles were identified and their key findings summarized in this review. Conclusion: OCT studies in schizophrenia patients conducted in recent years continue to provide evidence of retinal structural alterations associated with schizophrenia. However, the findings of these studies vary and there is a need to conduct further studies for clarification regarding the subject. The application of OCT and other neuroimaging techniques to correlate retinal structural alterations with schizophrenia may potentially help establish the role of retinal variables as biomarkers for the disease, and may open a gateway for better diagnostic investigations in schizophrenia.
