Abstract：
UNASSIGNED: Differentiation of iris and ciliary body lesions as benign or malignant and cystic or solid is important. The aim of this study was to compare anterior segment swept-source optical coherence tomography (AS SS-OCT) and ultrasound biomicroscopy (UBM) findings in iris and ciliary body tumors.
UNASSIGNED: Forty-two eyes of 38 cases with iris and ciliary body tumors imaged with UBM and AS SS-OCT between September 2018 and September 2023 were evaluated retrospectively.
UNASSIGNED: Of 42 eyes, 14 had melanoma, 14 iris pigment epithelial (IPE) cysts, 7 nevi, 3 Lisch nodules, 2 iris stromal cysts, 1 pars plana cysts, and 1 iris mammillations. An equivalent (100%) visualization of the anterior tumor margin was obtained with both techniques. Compared to AS SS-OCT, UBM was superior for posterior margin visualization in melanocytic tumors and IPE cysts. Bland-Altman plots demonstrated good agreement between UBM and AS SS-OCT for melanocytic tumors < 2.5 mm in base diameter and < 2 mm in thickness.
UNASSIGNED: Although, UBM is the gold standard for ciliary body and iridociliary tumors. AS SS-OCT should be considered as an excellent alternative to UBM, especially in minimally elevated iris lesions.

摘要：
■将虹膜和睫状体病变区分为良性或恶性以及囊性或实性是重要的。这项研究的目的是比较虹膜和睫状体肿瘤的眼前段扫频源光学相干断层扫描（ASSS-OCT）和超声生物显微镜（UBM）发现。
■回顾性评估了2018年9月至2023年9月间使用UBM和ASSS-OCT成像的38例虹膜和睫状体肿瘤的42只眼。
■42只眼睛,14人患有黑色素瘤，14虹膜色素上皮（IPE）囊肿，7nevi,3Lisch结节，2个虹膜基质囊肿,1个平面囊肿，和1个虹膜乳头。两种技术均获得了肿瘤前缘的等效（100％）可视化。与ASSS-OCT相比，UBM在黑素细胞肿瘤和IPE囊肿的后缘可视化方面优于UBM。Bland-Altman图表明，对于基底直径<2.5mm和厚度<2mm的黑素细胞肿瘤，UBM和ASSS-OCT之间具有良好的一致性。
■虽然,UBM是睫状体和虹膜睫状体肿瘤的黄金标准。SS-OCT应被视为UBM的优秀替代品，尤其是在最低限度的虹膜病变中。
