Correlations Between Retinal Nerve Fiber Layer and Visual Field in Eyes With Nonarteritic Anterior Ischemic Optic Neuropathy

In patients with NAION, RNFL measured by OCT provided better correlation to HVF changes than SLP did. Both instruments showed decreased RNFL in NAION eyes with altitudinal VF defects compared with control eyes, demonstrating loss of RNFL even in sectors of the optic disk that corresponded to relatively unaffected hemifield, suggesting greater damage beyond the extent estimated by VF methods.
