Graph describing proposed changes in transport and disc height with degeneration. In non-degenerate discs, there is an unimpeded transport cycle (A). An optimal range of transport properties permits this balance. As degeneration proceeds, structural and biochemical changes to the CEP and disc reduce transport properties, inhibiting transport (B). In advanced degeneration, transport is enhanced but disc height substantially decreases (C).
