Pitfalls in the clinical ophthalmologic examination of child ren, such as optic nerve pallor and pigmentary retinopathy, can be cla rified by these tests. Investigation of neurodegenerative disease may be directed to the most likely defect by results of visual evoked pote ntial testing and electroretinography. The child who is unable to mean ingfully communicate sensory experience can be objectively evaluated b y these studies. Familiarity with the applications and limitations of these tests will allow the examiner to choose the appropriate setting and time to apply each of them.
