Extended Data Fig. 9: Model fits for estimating retinal oxygen consumption.
From: Oxygen-free metabolism in the bird inner retina supported by the pecten

Measured (blue points) and modelled (red lines) oxygen partial pressure profiles were used to estimate the uninhibited and realized oxygen consumption rates of the retina and the oxygen fluxes from the choroid and the pecten. The 11 panels show the data from 11 individual anaesthetized zebra finches measured during ventilation with air. Data are plotted as a function of eye radius, where r = 0.18 cm represents the position of the choroid.
