vision/eye
• decline in visual performance
• photopic b wave decrease occurs only after 4 months
• photopic behavior performance at 95% of normal through 3 months
|
• decline in visual performance
• decline in scotopic b wave amplitudes at all flash intensities starting at 1.4 months
• mild optokinetic tracking defects before 2.5 months with a decline of the scotopic a wave
• a further decline at 4 months linked to catastrophic loss of optomotor responsiveness
