Summary of visual field defects

✍ 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
