PURPOSE
To evaluate arteriovenous malformations (AVM) with swept-source (SS) optical coherence tomography (OCT) angiography (OCTA) in iris racemose hemangioma and compare it with traditional intravenous iris fluorescein angiography (IVFA).
METHODS
A cross-sectional observational clinical study was conducted on patients with iris racemose hemangioma with the ZEISS PLEX Elite 9000 SS OCT & OCTA.
RESULTS
Three eyes of three patients were imaged. Iris racemose hemangiomas demonstrated a tortuous, well-defined, and continuous course of the AVM. The ZEISS PLEX Elite 9000 SS OCT & OCTA allowed for a detailed visualization of the ARM and was superior to IVFA in depicting small caliber, fine vessels.
CONCLUSIONS
SS-OCTA may provide a dye-free, no-injection, cost-effective method comparable to spectral domain OCTA and IVFA for diagnosing and monitoring iris racemose hemangiomas for growth and vascularity.
目的
利用扫频源（SS）光学相干断层扫描血管造影（OCTA）评估虹膜蔓状血管瘤中的动静脉畸形（AVM），并将其与传统的静脉内虹膜荧光血管造影（IVFA）进行比较。
方法
使用蔡司PLEX Elite 9000 SS OCT和OCTA对虹膜蔓状血管瘤患者进行横断面观察性临床研究。
结果
对3例患者的3只眼进行了成像。虹膜蔓状血管瘤表现出AVM迂曲、边界清晰且连续的走行。蔡司PLEX Elite 9000 SS OCT和OCTA能够详细显示AVM，在描绘小口径、细小血管方面优于IVFA。
结论
SS-OCTA可能为诊断和监测虹膜蔓状血管瘤的生长及血管情况提供一种无需染料、无需注射且具有成本效益的方法，可与光谱域OCTA和IVFA相媲美。
