Purpose. To describe the SD-OCT findings in patients with diffuse unilateral subacute neuroretinitis (DUSN) and evaluate CRT and RNFL thickness. Methods. Patients with clinical diagnosis of DUSN who were submitted to SD-OCT were included in the study. Complete ophthalmologic examination and SD-OCT were performed. Cirrus scan strategy protocols used were 200 × 200 macular cube, optic nerve head cube, and HD-5 line raster. Results. Eight patients with DUSN were included. Mean RNFL thickness was 80.25 μm and 104.75 μm for affected and normal eyes, respectively. Late stage had mean RNFL thickness of 74.83 μm compared to 96.5 μm in early stage. Mean CMT was 205.5 μm for affected eyes and 255.13 μm for normal fellow eyes. Conclusion. RNFL and CMT were thinner in DUSN eyes compared to normal eyes. Late-stage disease had more pronounced thinning compared to early-stage patients. This thinning in RNFL and CMT may reflect the low visual acuity in patients with DUSN.
目的。描述弥漫性单侧亚急性神经视网膜炎（DUSN）患者的频域光学相干断层扫描（SD - OCT）检查结果，并评估中央视网膜厚度（CRT）和视网膜神经纤维层（RNFL）厚度。方法。本研究纳入临床诊断为DUSN且接受SD - OCT检查的患者。进行了全面的眼科检查和SD - OCT检查。所使用的Cirrus扫描策略方案包括200×200黄斑立方体、视神经乳头立方体和HD - 5线光栅扫描。结果。纳入8例DUSN患者。患眼和正常眼的平均RNFL厚度分别为80.25μm和104.75μm。晚期患者的平均RNFL厚度为74.83μm，而早期患者为96.5μm。患眼的平均CMT为205.5μm，对侧正常眼为255.13μm。结论。与正常眼相比，DUSN患者患眼的RNFL和CMT更薄。与早期患者相比，晚期疾病的变薄更为明显。RNFL和CMT的这种变薄可能反映了DUSN患者的低视力。
