Abstract

Objectives: 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.

Research design and methods: 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.

Results: 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.

Conclusions: 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.

虹膜和睫状体病变的前段扫源光学相干断层扫描和超声生物显微镜。

目的：区分虹膜和睫状体病变是良性还是恶性，是囊性还是实性非常重要。本研究旨在比较虹膜和睫状体肿瘤的前段扫源光学相干断层扫描（AS SS-OCT）和超声生物显微镜（UBM）检查结果：对2018年9月至2023年9月期间38例虹膜和睫状体肿瘤患者的42只眼睛进行回顾性评估：42只眼睛中，14只患有黑色素瘤，14只患有虹膜色素上皮（IPE）囊肿，7只患有痣，3只患有Lisch结节，2只患有虹膜基质囊肿，1只患有平滑肌旁囊肿，1只患有虹膜乳头状瘤。两种技术对肿瘤前缘的观察结果相当（100%）。与 AS SS-OCT 相比，UBM 在黑色素细胞肿瘤和 IPE 囊肿的后缘显像方面更胜一筹。Bland-Altman图显示，UBM和AS SS-OCT在黑色素细胞肿瘤方面具有良好的一致性：尽管 UBM 是睫状体和虹膜睫状体肿瘤的金标准。AS SS-OCT 应被视为 UBM 的最佳替代品，尤其是在虹膜病变微隆起的情况下。
