Summary

This gives a good idea of what glaucoma patients see, useful when considering development test cases.

• visual field test can be difficult, requiring an understanding of what is required, an ability to perform tasks quickly, and high levels of concentration
• Manual and/or automated visual field testing is subjective: it is totally dependent on the co-operation and responses of the patient
• Abnormalities in the visual field are a sign of damage anywhere in the visual system from the retina through to the brain's visual cortex
• when defects do not overlap, the field defects will not be apparent when the scene is viewed with both eyes together
• diagnostic purposes, it is important to test each eye separately
