“…The present study revealed that both the affected and unaffected eyes were significantly different between OAG and NAION patients using the visual field test as well as spectral domain OCT. Altitudinal visual field defects are considered common in NAION (especially inferior visual field defects) because of the typical vascular supply of the optic disc [ 5 ]. However, altitudinal visual field defects can also be seen in patients with glaucoma, other optic nerve disorders, and chiasmal lesions [ 10 ]. In the present study, inferotemporal rim loss was usually more pronounced in glaucoma patients, therefore superior visual field defects were more common.…”

PurposeTo investigate the differences in retinal nerve fiber layer (RNFL) change and optic nerve head parameters between non-arteritic anterior ischemic optic neuropathy (NAION) and open angle glaucoma (OAG) with altitudinal visual field defect.MethodsSeventeen NAION patients and 26 OAG patients were enrolled prospectively. The standard visual field indices (mean deviation, pattern standard deviation) were obtained from the Humphrey visual field test and differences between the two groups were analyzed. Cirrus HD-OCT parameters were used, including optic disc head analysis, average RNFL thickness, and RNFL thickness of each quadrant.ResultsThe mean deviation and pattern standard deviation were not significantly different between the groups. In the affected eye, although the disc area was similar between the two groups (2.00 ± 0.32 and 1.99 ± 0.33 mm2, p = 0.586), the rim area of the OAG group was smaller than that of the NAION group (1.26 ± 0.56 and 0.61 ± 0.15 mm2, respectively, p < 0.001). RNFL asymmetry was not different between the two groups (p = 0.265), but the inferior RNFL thickness of both the affected and unaffected eyes were less in the OAG group than in the NAION group. In the analysis of optic disc morphology, both affected and unaffected eyes showed significant differences between two groups.ConclusionsTo differentiate NAION from OAG in eyes with altitudinal visual field defects, optic disc head analysis of not only the affected eye, but also the unaffected eye, by using spectral domain optical coherence tomography may be helpful.
