Purpose To compare the pattern of peripapillary retinal nerve fiber layer (RNFL) damage in between primary open angle glaucoma (POAG) and nonarteritic anterior ischemic optic neuropathy (NAION). Methods Thirty‐two eyes of 32 patients with unilateral NAION and 60 eyes of 60 patients with POAG were consecutively enrolled in this study. The age, sex, and average RNFL thickness of the POAG were matched by those of the NAION. All of the patients underwent thorough eye examination including Cirrus HD optical coherence tomography (Carl Zeiss Meditec, Dublin, CA, USA). Peripapillary RNFL thickness in the 4 quadrants and 12 clock hours were compared in both groups. Results RNFL thickness of the nasal 1 o'clock area in NAION was significantly thinner compared to POAG (64.0 ± 18.9 and 75.8 ± 22.4 μ m, p = 0.014). RNFL thickness of temporal 7 o'clock area in POAG was significantly thinner compared to NAION (78.7 ± 32.1 and 100.9 ± 42.1 μ m, p = 0.006). Conclusions RNFL thickness of nasal quadrant and superonasal sector was thinner in NAION. RNFL thickness of the inferotemporal sector was thinner in POAG.
