A normal visual field extends approximately TEMPORALLY – 100 deg NASALLY – 60 deg SUPERIORLY – 60 deg INFERIORLY – 70 deg A physiologic scotoma (a blind spot) exists at 15° temporally where the optic nerve leaves the eye 10-2: Measures 10 degrees temporally and nasally and tests 68 points. Used for macula, retinal and neuro-ophthalmic conditions and advanced glaucoma[4] 24-2: Measures 24 degrees temporally and 30 degrees nasally and tests 54 points. Used for neuro-ophthalmic conditions and general screening[5] as well as early detection of glaucoma[6][7] 30-2: Measures 30 degrees temporally and nasally and tests 76 points. Used for general screening, early glaucoma and neurological conditions[6] The above tests can be performed in either SITA-Standard or SITA-Fast. SITA-Fast is a quicker method of testing. It produces similar results compared to SITA-Standard, however repeatability is questionable and it is slightly less sensitive 10-2: Measures 10 degrees temporally and nasally and tests 68 points.

1. VISUAL FIELDS

2. • A normal visual field extends approximately
• TEMPORALLY – 100 deg
• NASALLY – 60 deg
• SUPERIORLY – 60 deg
• INFERIORLY – 70 deg
• A physiologic scotoma (a blind spot) exists at 15° temporally where the optic
nerve leaves the eye

4. Humphey perimetry
• 10-2: Measures 10 degrees temporally and nasally and tests 68 points.
Used for macula, retinal and neuro-ophthalmic conditions and
advanced glaucoma[4]
• 24-2: Measures 24 degrees temporally and 30 degrees nasally and tests
54 points. Used for neuro-ophthalmic conditions and general
screening[5] as well as early detection of glaucoma[6][7]
• 30-2: Measures 30 degrees temporally and nasally and tests 76 points.
Used for general screening, early glaucoma and neurological conditions[6]
• The above tests can be performed in either SITA-Standard or SITA-Fast.
• SITA-Fast is a quicker method of testing. It produces similar results
compared to SITA-Standard, however repeatability is questionable and it is
slightly less sensitive

5. HOW TO READ VISUAL FIELD
ZONE 1 - Patient and test data
ZONE 2 - Reliability index and
foveal threshold
ZONE 3- Gray scale
ZONE 4 - Total deviation plot
ZONE 5- Patern deviation plot
ZONE 6 - Global indices
ZONE 7 - Glaucoma hemifield
tests

6. GOLDMANN PERIMETER

7. ANDERSON CRITERIA
• 3 Or more congruous ‘ non edge ‘ points in typical arcuate area
Depressed p <5% with atleast one point p<1%
• Pattern standard deviation p <5%
• GHT – outside normal limits
Must be demonstrated on 2 field tests
Include all 3 – high specificity
