| Summary: | The <i> Heidelberg retina angiograph</i> (<i> HRA) classic</i> enables fluorescein angiography (FA) and indocyanine green angiography (ICG-A) of the retina and choroid. The goal of this study was to design an accessory device to adapt the <i> HRA classic</i> for application on structures anterior to the retina. The optical device consisted of a cylindrical two-piece plastic frame holding a magnifying lens commonly used with the indirect ophthalmoscope. A 60-diopters lens was inserted in this frame to enable the angiography of the anterior segment. A less strong lens of 30 diopters was used for the visualization of pathologic findings in the vitreous cavity. We designed an easy-to-use and low-cost device to adapt the <i> HRA classic</i> for angiography of the fundus, vitreous cavity and anterior segment in the same session and without delay. FA and ICG-A images of two patients with rubeosis iridis and of one patient with choroidal melanoma are described.
