Changes in angle lambda during growth: theory and clinical applications.
The eye undergoes rapid growth during the first years of life. Using a mathematical model, we analyzed angle lambda from birth through adult life to determine what change in its magnitude occurs with growth of the eye. The effect of changes in angle lambda on measurement and correction of astigmatic errors and on the analysis of fixation patterns are discussed.
