A recent report suggested that choroidal circulation impairment correlates with its pathogenesis. We report a rare case with simultaneous onset of AMN and central retinal vein occlusion (CRVO), which is a retinal circulation disorder.
Methods: Case report.
Results: A 44-year-old woman complained of central visual loss of the left eye for the previous 2 weeks. The patient’s visual acuity was 0.5 in the left eye (OS). Fundoscopic examination revealed a wedge-shaped, dark reddish-brown lesion at the macula, and CRVO-like retinal hemorrhages OS. Fluorescein angiography revealed retinal vasculitis and hypofluorescence corresponding to the macular lesion. The patient’s scanning laser ophthalmoscopy infrared imaging result led to a diagnosis of AMN. Two weeks after corticosteroid pulse therapy, her visual acuity improved to 1.2 OS, with improvement of macular findings and Humphrey perimetry. When the dose of oral corticosteroid was decreased, the AMN lesion worsened, with recurrence of retinal hemorrhages. Visual functions improved again after an increased dose of corticosteroid.
Conclusion: These results suggest that circulatory disorders almost simultaneously
occurred in choroidal and retinal vessels, resulting in the onset of both AMN and CRVO.Dove Medical Press2013-07-15engjournal articleVoRhttp://hdl.handle.net/2115/54612http://www.dovepress.com/a-patient-with-acute-macular-neuroretinopathy-and-central-retinal-vein-peer-reviewed-article-OPTHhttps://doi.org/10.2147/OPTH.S47045238851681177-54671177-5483AA12240029Clinical Ophthalmology714471450https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/54612/1/Clin%20Ophthalmol_7_1447-1450.pdfapplication/pdf1.33 MB2013-07-15
