Retinal Field Defects
✍ The pattern you see on the retina is seen on the visual field
✍ Any defect that does not respect the vertical meridian should be considered

Optic Nerve Field Defects
✍ Optic nerve scotomas
☝Central
☝Centrocecal
☝Arcuate
✍ Optic nerve depressions
☝ Nasal steps (with respect for the horizontal meridian)
☝ Altitudinal defects
☝ Temporal wedges starting at the blind spot.
✍ Any defect that does not respect the vertical should be considered
Chiasmal Field Defects
✍ Bitemporal
✍ Junctional defect
☝ common type : an ipsilateral optic nerve defect and a contralateral upper temporal
defect that respects the vertical
☝ rare type : a unilateral defect that stops
sharply at the vertical meridian
✍ A binasal defect
✍ Bow- tie optic atrophy
OpticTract VF defects
✍ contra lateral Incongruous visual field defects
✍ Contralateral optic disc bow tie atrophy
Lateral Geniculate Body VF defects
✍ Homonymous pie-shaped defects that center on fixation
✍ incomplete incongruous homonymous hemianopias
✍ Contralateral optic disc bow tie atrophy
Optic Radiations VF defects
✍ Mildly incongruous defects
Occipital Lobe VF defects
✍ Marked congruity of visual field defects
✍ Macular sparing.
✍ Very small homonymous hemianopic scotomas
✍ Monocular loss or sparing of the unpaired temporal crescent
✍ Quadrantic defects that stop sharply at the horizontal meridian
✅ Summary of VF defects The Diffusely Depressed Field DD
☝Media opacity
☝miosis (diminished light stimulus )
☝Poor attention
☝Optic nerve disease
✅ Summary of VF defectsThe Severely Constricted “Key Hole” Field DD
☝ Retinal disease (RP ) and may need an ERG
☝ Optic nerve disease (an obvious disc change should be seen)
☝ Bilateral peripheral homonymous hemianopias (the residual field should show a vertical step)
☝ Functional
