Optic Nerve and Retinal Nerve Fiber Imaging - EyeWiki
The optic nerve (optic disc, optic disk, optic nerve head [ONH]) area is approximately 2.1-2.8 mm 2 in whites who are not highly myopic depending on the measurement method utilized. The optic nerve size changes in early life and is likely stable after age 10.
Evaluating the Optic Nerve for Glaucomatous Damage With OCT
The Stratus OCT measured retinal nerve fiber layer (RNFL) thickness via a 3.5-mm-diameter circle centered on the optic disc and used radial scans to provide measurements of the optic nerve head (ONH) such as disc, cup, and rim area.

Optic Nerve Hypoplasia - American Academy of Ophthalmology
Jun 1, 2021 · Optic nerve hypoplasia (ONH) is an important cause of congenital visual impairment in children and infants. It is a unilateral or bilateral malformation of the optic nerve with a wide spectrum of severity.
Spectral Domain Optical Coherence Tomography in Glaucoma
ONH parameters have also been found to have excellent ability to discriminate between normal eyes and eyes with even mild glaucoma. The parameters found to have the greatest diagnostic capability are vertical rim thickness, rim area, and vertical cup to disc ratio.
