BACKGROUND: 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. METHODS: Twenty-eight patients with PXS in both eyes underwent an ophthalmic examination, including IFA and IICGV. IICGV was performed with the IMAGEnet system H1024. RESULTS: IICGV gave better visualization of iris hypoperfusion and anastomotic vessels, whereas iris microneovascularization was far more clearly visible on IFA. IICGV also detected iris pigment epithelium defects. CONCLUSIONS: 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.
