| Summary: | 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.
