WebA schematic eye is a mathematical or physical model that represents the basic optical features of the real eye. By its nature, it is a simplified version and there is a range of schematic eyes that have been developed which offer different levels of simplicity or complexity, from the simplest reduced version that consists of a single refracting surface … Webthe axial lengths of the schematic eyes are given by AL (mm) = 23.182 + 0.0102A (4) which increases the length by 0.17mm and 0.12 mm at ages of 20 years and 70 years, respectively. The common paraxial schematic eyes have equivalent refractive indices of about 1.42, and that of my schematic eyes is higher at nL = 1.4506 – 0.00035A (5)

http://www.medrounds.org/optics-review/2006/05/21.html WebUsing the model eye parameters from this study, this difference would change the length of a 30° OCT line-scan by 4% (60 μm/1593 μm). However, AL can change by almost 2 mm, from 5 mm at 1 month of age to 6.8 mm at 15 months of age. This will effectively change the length of a 30° OCT line scan by 46% (600 μm/1900 μm).
