Purpose: To identify changes in superficial retinal capillary microvasculature before and after cataract surgery using
optical coherence tomography angiography (OCTA).
Setting: Rajan eye care, Tertiary care center in Chennai, India.
Design: Prospective observational study.
Methods: Patients above 40 years who underwent uncomplicated cataract surgery had 6 × 6 mm OCTA foveacentered
scans using Zeiss Angioplex 5000 OCTA before and 4 weeks postoperatively. Signal strength and automated
values obtained for perfusion density (PD) and vascular density (VD) were recorded.
Results: Fifty-eight eyes of 33 patients aged 67 ± 5 years were enrolled. Signal strength (3.9 ± 2.3 vs. 5.7 ± 2.1,
p<0.001), PD (16.4 ± 10.4 vs. 26.6 ±.. View More»
