OCT Angiography

There are now 4 companies which manufacture a device which can determine flow of the retinal and choroidal circulations without the use of a contrast dye. The risk of intravenous dye injection is eliminated and these circulations and their abnormalities can be imaged with high discrimination and resolution. The Macula Foundation is supporting research in all four of these devices to determine their benefits, advantages, and limitations. This is one of the most prominent new developments and advances in the field of retina.
