This document describes the confrontation visual field test procedure in 3 stages: 1. The examiner seats the patient and occludes the non-tested eye. They face the patient at 1 meter and occlude their eye opposite the patient's occluded eye. 2. Finger counting is done by quickly presenting and retracting 1 finger in each visual field quadrant twice, then repeating across quadrants. Simultaneous counting uses 1-2 fingers in opposite quadrants and asks the patient to sum. 3. Simultaneous comparison holds identical objects toward the patient's central and eccentric vision, asking about brightness differences. A diagram should show the 3 test stages and note a normal result as counting fingers fully.

1. Confrontation fields test

Dr. Alshymaa Moustafa
Ophthalmology specialist

2. Visualfield
 It contains :
1. Centeral or foveal which is measured by visual acuity
test, contrast senstivity and macular function tests
.and concerned with Resolution, forms.
2. Peripheral or Extrafoveal which is concerned with
Peripheral sensitivity , motion and light detection.
 Normal visual field is reversed inverted map of
corresponding retinal points .

3. • The normal extensions of visual field are
:
1. °
50 Suoerior
2. °
60 Nasal
3. °
70 Inferior
4. °
90 Temporal.

4. Perimetery
 It is making of visual field using stimulus.
 The stimulus may be
1. Moving (kinetic) determine the visual threshold
along edge of visual field.
2. Static in which the static object has different level of
brightness.

5. Confrontation
fieldstest
 It is used as screening for moderate to sever visual
field defects.
 It is un reliable to identify Mild visual field defects.
 Note
1. Face to face position.
2. Start with better eye.
3. Avoid confusion by using 1,2,5 fingers.
4. If the patient can’t count fingers, use hand motion , if
can’t use light projection.
5. Young child use finger mimicking procedure.

6. Correct position :
2 finger sud by side in front of the eye field .
Incorrect position:
One finger hide the other

7. Clinical protocol
Test steps:

8. Teststeps
1. .Seat the patient and occlude the eye not being
tested.
2. Facing the patient at a distance 1 m , close your eye
that is directly opposite to the patient occluded eye.
3. Ask the patient to fixate on your nose or your opened
eye.

9. Checkfor
scotoma
 Finger counting :
1. Quickly present and retract 1finger in 1 hand in 1quadrant.
2. Must be done 2 times in each quadrant.
3. Repeat in 4 quadrants.
 Simultaneous finger counting;
1. Use 1,1 or 1,2 or 2,2 fingers simultaneously in opposition quadrants.
2. Ask the patient for sum.
 Simultaneous comparison:
1. Hold both palm, or identical coloured objects to words the patient close line
of sight.
2. Ask for difference in brightness or darkness.
3. Do it central , eccentric.

13. Diagramthe
test
• Diagrams showing 3 stages of the test .
• If normal write Full to 3 stage
confrontation or counting fingers .
