Foveal avascular zone area measurement using OCT angiography

• Optical coherence tomography angiography is an effective tool in measuring the foveal avascular zone area in healthy as well as diseased eyes. • Various factors like diabetes, hypertension, smoking, etc can affect the foveal avascular area independently. • Larger sample size should be included to establish baseline foveal avascular zone area in healthy eyes of a particular race or geographical location.
