The RNFL thickness decrease with longer axial length is associated with a longer optic disc-fovea distance and larger parapapillary gamma zone. Longer disc-fovea distance and larger gamma zone lead to an elongation and stretching of the retinal nerve fibres, potentially causing a thinning or loss of the nerve fibres. It may explain the occurrence of visual field defects in some non-glaucomatous highly myopic eyes without macular correlates of the perimetric defects.
