FUNCTIONAL HEMIANOPIAS ON HUMPHREY VISUAL-FIELD ANALYSIS

We report two cases of uniocular hemianopia that we first detected on Humphrey visual field analysis, with one patient having additional con striction of his peripheral visual fields bilaterally, These field def ects were confirmed to be functional in nature after characteristic ch anges on Goldmann perimetry and spontaneous improvement towards normal . This type of functional field loss is rare and the unusual pattern o n computerised perimetry should be recognised for managing the patient appropriately.
