Summary

This study aimed to see if a simple eye scan could predict which people with early schizophrenia would benefit from a drug called sodium nitroprusside. The drug was given to reduce psychosis symptoms like delusions and hallucinations. Only one person enrolled before the study was stopped, so no clear conclusions can be drawn.
