Summary of VF 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 defectsThe 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
