The area of the neuroretinal rim of the optic nerve in normal eyes

Am J Ophthalmol. 1987 Apr 15;103(4):497-504. doi: 10.1016/s0002-9394(14)74271-0.


We randomly photographed 113 eyes in 113 people without ocular disease. The area of the disk and its neuroretinal rim as well as the width of the disk and cup were measured. The measurements were corrected for magnification of each eye by measuring its refraction and axial length. A linear correlation between disk area and neuroretinal rim area was found (r = .75) as well as a correlation between the disk area and the cup area (r = .83). There was no correlation between age and disk area or rim area.
