Figure 6.

Model validation with rd1 cone density data. The cone density data represents cone cell count per mm². In³⁰, each square millimeter is referred to as a field. There are approximately 300 fields with surface area 0.0376 mm². Our mathematical model produces values for C throughout the retina instead of within a particular surface area. Thus, we divide the model output, C, by (300 · 0.0376). The data points in the plots correspond to the mean cone densities at postnatal days 15, 35, 43, 60, and 90. In the model simulation we consider a time span of t₀ = 0 minutes to t_f = 12.96 × 10⁴ minutes (90 days), δ = 30 × 10⁻⁹ and μ_c = 0.09 × 10⁻³. All other parameter values are the same as in Table 2. In (B), the image is zoomed in to show the presence of small oscillations even around the 90 day time point.
