Precise evaluation of the iris vascular pattern in pseudoexfoliation syndrome (PXS) may be difficult with iris fluorescein angiography (IFA) because of the frequent presence of a heavily pigmented iris and conspicuous late leakage. However, iris indocyanine green videoangiography (IICGV) can precisely visualize details of the iris vascular pattern. This study analyzed the utility of IICGV in detecting microvascular changes in PXS and compared these findings with those of IFA.
Twenty-eight patients with PXS in both eyes underwent an ophthalmic examination including IFA and IICGV. IICGV was done with the IMAGEnet system H1024.
IICGV gave better visualization of iris hypoperfusion and anastomotic vessels whereas iris microneovascularisation was far more clearly visible on IFA. IICGV also detected iris pigment epithelium defects.
IICGV can be considered a useful tool for evaluation of the iris vascular pattern in PXS. Iris hypoperfusion did not appear to contribute to the development of iris microvascular changes.
在假性剥脱综合征（PXS）中，由于虹膜色素沉着严重且晚期渗漏明显，使用虹膜荧光血管造影（IFA）可能难以精确评估虹膜血管形态。然而，虹膜吲哚青绿视频血管造影（IICGV）能够精确显示虹膜血管形态的细节。本研究分析了IICGV在检测PXS微血管变化中的作用，并将这些结果与IFA的结果进行比较。
28例双眼患有PXS的患者接受了包括IFA和IICGV在内的眼科检查。IICGV使用IMAGEnet系统H1024进行。
IICGV能更好地显示虹膜灌注不足和吻合血管，而虹膜微血管化在IFA上更清晰可见。IICGV还检测到虹膜色素上皮缺损。
IICGV可被视为评估PXS中虹膜血管形态的有用工具。虹膜灌注不足似乎与虹膜微血管变化的发生无关。
