This powerpoint presentation by Dr. Luisa Mayer was given at the 2005 ADVISOR workshop.

1. Visual field testing in pediatrics Confrontation Arc perimetry Hemispheric perimetry Goldmann perimetry 1 – DL Mayer, 3-14-05

2. The Count “eats” the white ball when the infant orients to it (looks at it) Confrontation with the Count and the white ball 2 – DL Mayer, 3-14-05

3. Arc perimetry Orienting to a flashing light on 4 oblique meridia, at 20 and 30 deg Child with CP – Detects lights in superior left 3 – DL Mayer, 3-14-05

4. Orienting to a flashing light at a fixed extent on one of 24 half meridia Hemispheric perimetry 4 – DL Mayer, 3-14-05
