Table 2 Mean (SD) RNFL values measured across normal subjects. Figure 2 NettetOptical coherence tomography can also be used to follow up the subsequent resolution of axonal swelling and thinning of the RNFL, which are essential aspects of optic atrophy. Future studies using OCT in various optic neuropathies hold the promise of elucidating the reversible and irreversible changes associated with optic disc edema.
NettetIn evaluating RNFL of patients with long AL, a 16–22 μm average thinning compared to the nomogram can be tolerated and prominent nasal thinning likely represent changes from axial elongation. Temporal RNFL thinning in those with long AL tends to be mild, and any significant thinning in this area should raise suspicion for glaucomatous changes.
