To evaluate the macula with spectral domain type optic coherence tomography (OCT) in eyes with acute nonarteritic anterior ischemic optic neuropathy (NAION) at the presentation visit.
Medical charts of the 133 patients who received the diagnosis of acute NAION between January 2008 and July 2014 at the Neuro-ophthalmology unit of Dokuz Eylul University were reviewed retrospectively. Sixtythree patients within 30 days of symptom onset with available baseline spectral domain type macular OCT were included in this study. Clinical and macular characteristics of the affected eye were assessed and compared to the fellow eyes.
Sixty-three eyes of 63 patients comprised the study group. Twenty one study eyes (33.3%) had normal posterior pole, 22 (34.9%) some evidence of subretinal fluid, 10 (15.8%) vitreomacular adhesion, five (7%) age-related macular degeneration related changes, four (6%) epiretinal membrane and one (1%) previous grid laser scars. On the other hand, 41 of 63 the fellow eyes (65%) had normal posterior pole, ten (15.8%), vitreomacular adhesion, seven (10.7%), age-related macular degeneration related changes, three (4%) epiretinal membrane and two (3%) other type of changes. OCT scan passing through the fovea exhibited 10 or more hyperreflective dots in 10 (15%) of the study eyes whereas two of the fellow eyes (3.2%) had 10 or more hyperreflective dots.
Macular OCT can be a part of the routine neuroophthalmologic examination in patients with acute NAION not only to show the NAION related changes such as the subretinal fluid accumulation but also to identify the other coexistent macular abnormalities.
