[Hypertensive choroid angiography. Initial results].
A new method for the examination of choroidal morphology and hemodynamics by SLO-ICG videoangiography under induced hypertension by ocular ophthalmodynamography is presented. In 17 normal subjects, 32 patients suffering from exudative age-related macular degeneration and 13 patients suffering from subretinal fibrosis, the arterial blood vessels of the choroid were demonstrated in detail angiographically. Perfusion pressures of posterior ciliary arteries at their entry into the eye were also estimated. In the majority of patients in each group the central retinal artery was first filled with dye; in the central 40 degrees field 5-8 posterior ciliary arteries were detected; the arterial branches of the submacular choroid were supplied by a submacular ciliary artery in more than half of the cases; however, dye filling of the submacular choroid occurred later than in the surrounding choroid during reduction of intraocular pressure. ICG fluorescence angiography is compared to other angiographic examination methods of choroidal morphology and hemodynamics.
