Optical coherence tomography angiography (OCTA) is a non-invasive test used to visualize the vascular structures of the retina. With OCT-A, high-definition digital images of the blood vessels can be quickly obtained and analyzed.
Optical Coherence Tomography Angiography can help detect conditions such as:
Unlike traditional fluorescein angiography, OCT-A does not require a dye injection into an arm vein. The doctor may apply eye drops to dilate the eye. The equipment will then scan the eye without touching it.
OCT-A allows the doctor to detect diseases of the retina that affect the ocular blood vessels at early stages. This technology has made timely intervention possible for a number of retinal conditions.
The imaging allows the doctor to see the blood vessels in the retina. The doctor will repeat imaging and analysis of the same area over time in order track disease progression.
