✍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
