Scatoma
Area where vision is partially or fully reduced
Ipsilateral
VF defect on same side of lesion
Contralateral
VF defect on opposite side compared to lesion
Homonymous
Affecting same part of the visual field of each eye
Hemianopia
Half of the visual field had a defect
Quadrantanopia
Quarter of visual field has a defect

Reliability indices (Components of Humphreys)
- False Positive (Trigger happy)
- False negative (Stimulus is shown in area px has already seen but was missed this time)
- Fixation Losses
Threshold Values (Components of Humphreys)
- How bright was stimulus
- Higher number = Dimmer light
- Measured in dB
Greyscale map (Components of Humphreys)
Visual presentation of raw data (Black area is blind spot)
Numerical total deviation map (Components of Humphreys)
Total dB deviations from the norms for that age
Numerical pattern deviation map (Components of Humphreys)
Corrects for any overall reduction in vision
Total deviation probability map (Components of Humphreys)
Visual representation of probability of deviations outside the age norms; Taking the above numerical data and representing it in a map with probability
Pattern deviation probability map (Components of Humphreys)
Visual representation of the probability of the reduction in vision after correcting for any overall reduction
Probability symbols (Components of Humphreys)
Darker the square the more likely the defect is not normal
