To report the optical density of the superfical retinal small vessel network and deep retinal capillary network in normal Chinese adult.
A spectral-domain optical coherence tomography angiography (SD-OCTA) devices (Cirrus; Carl ZeissMeditec, Inc, Dublin, California, USA) were used to capture the superficial and deep retinal vascular plexus. The Image Pro Plus (Medical Cybernetics, Version 6.0) software was used to grading the optic density of the image.
A total of 64 eyes of 64 subjects (51% male) were analyzed. The mean age was 44±13 years old. The intra-observer reproducibility and inter-observer repeatability of this method was between 0.85 to 0.95 and 0.78 to 0.87, respectively. The general density of superficial para-papillary micro-vascular was 85.4±10.2, inferiorly, superiorly, nasally and temporally was 92.2±10.9, 92.4±9.8, 78±9.4 and 79.4±8.6, respectively. The general density of deep parapapillary micro-vascular was 59.5±6.9, inferiorly, superiorly, nasally and temporally was 60.2±6.9, 53.4±6.6, 64.2±9.8 and 61.2±8.3, respectively. The general density of superficial para-macular micro-vascular was 51.7±9.2, inferiorly, superiorly, nasally and temporally was 50.3±10.8, 54.2±9.7, 53.1±6.7 and 50.4±10.7, respectively. The general density of deep para-macular micro-vascular was 59.5±6.9, inferiorly, superiorly, nasally and temporally was 49.5±5.6, 49.3±6.9, 49.7±3.1 and 48.6±4.3, respectively.
The micro-vascular density was greater in vertical than horizontal, which was explained by the anatomy of the retina.
