dc.description.abstract목적: 스펙트럼 영역 빛간섭단층활영기(SD-OCT)에서 생기는 오류를 황반질환에 따라 분석하여 보고하고자 한다. 대상과 방법: 116명 116안을 대상으로 후향적 연구를 시행하였다. 정상안 40안과 망막내 병변이 있는 45안, 망막하 병변이 있는 31안을 대상으로 SD-OCT (3D-1000, Topcon Corp.,Japan)로 12×6 mm radial scan을 시행하였다. 각각의 스캔에서 나타나는 오류의 유형과 빈도를 조사하고 오류의 심각도를 점수화하여 질환군별로 비교하였다. 결과: 전체 116안 중 77안(66.38%)에서 최소 1개 이상의 오류가 발견되었다. 가장 흔한 오류는 망막두께의 내경계 설정 오류였고 (25.86%), 황반중심이탈의 오류는 10.34%, 부적합한 영상획득 오류는 15.52%, 외경계 설정 오류는 8.6%였다. 전반적 오류 빈도는 망막병리가 있을 경우 약 90%로 정상안 37.5%에 비해 월등히 높았다. 망막내 병변군이 다른 군보다 망막 외경계가 더 내측으로 설정되는 빈도가 높았다(p<0.01). 결론: SD-OCT는 황반질환에 따라 다양한 오류를 보이므로 OCT를 해석할 때 오류의 가능성을 항상 염두에 두어야 한다.-
dc.description.abstractPURPOSE To report the frequency, severity and various types of artifacts associated with spectral-domain optical coherence tomography (SD-OCT) based on macular pathologies. METHODS: Data was collected retrospectively from 116 eyes of 116 subjects. SD-OCT (3D-1000, Topcon Corp., Japan) imaging was performed in 40 healthy eyes, 45 eyes with intraretinal pathology (IRP) and 31 eyes with subretinal pathology (SRP). The scan protocol was 12x6 mm radial scan. The frequency and types of artifacts were investigated in each scan and were analyzed based on macular disease. Additionally, the effect of artifacts on the measurement of macular thickness was studied. RESULTS: Errors occurred in 77 eyes (66.38%). Inner retinal boundary misidentification (IRBM) was the most common error (25.86%), with the frequencies of other types of artifacts being 10.34% for off-center fixation, 15.52% for degraded image and 8.6% for outer retinal boundary misidentification (ORBM). The overall error rate of SD-OCT in the retinal pathology group was much higher than that in the normal group. Macular thickness was underestimated in the IRP group because the outer retinal boundary of the IRP group tended to be misidentified toward the inner retina (p<0.01). CONCLUSIONS: SD-OCT can frequently cause various types of artifacts in patients with macular disease. When interpreting OCT images, the artifacts of SD-OCT should be considered in order to obtain accurate macular thickness and to prevent erroneous clinical decisions.-
