Changes in retinal vasculature after phacoemulsification evaluated using optical coherence tomography angiography
Zhao et al. 1 describe changes in retinal vessel density and foveal avascular zone area after routine cataract surgery. These parameters were evaluated using optical coherence tomography (OCT) angiography, an exciting new imaging technology for noninvasive evaluation of the retinal microvasculature. 2 It has been reported that the foveal avascular zone, both in the superficial and deep retinal capillary plexus, varies significantly in size, even in normal healthy adults. 3
