Patients typically become symptomatic in their 40s due to loss of central vision. However, tests of rod photoreceptor function (i.e., night vision tests) show dysfunction at an earlier age. One of the most sensitive visual function parameters for early<unk>  is a prolongation of rod-mediated dark adaptation. High-resolution structural imaging of the Bruch's membrane and of the underlying choriocapillaris - the capillary plexus nourishing the outer retina - shows also early alterations.
