Optical coherence tomography

What is optical coherence tomography (OCT)?

OCT is an imaging technology that assesses the thickness of the peripapillary retinal nerve fibre layer, macular thickness, and volume. It has been used to assess neurologic diseases such as multiple sclerosis, Alzheimer’s disease, and Parkinson’s disease, and more recently, schizophrenia.

What is the evidence for OCT?

Moderate to low quality evidence suggests lower retinal nerve fibre layer thickness in people with schizophrenia compared to people without schizophrenia.
