Depth-coded OCT angiograph in a mouse cortex before and after focal ischemic stroke. (a) Pre-photothrombosis microvascular structure. A: middle cerebral artery. V: superficial pial veins (b) Post-photothrombosis microvascular structure. Scale bar: 500 µm. (c) and (d): OCT B-scan images taken from respective locations indicated by colored dashed line in (a) and (b). The red arrows indicate main artery (in purple square) and vein (in yellow square), respectively. (e)-(g) Vessel profile taken from respective lines indicated in (a) and (b) showing vessel dilation after photothrombosis. Blue line: pre-photothrombosis; red line: post-photothrombosis.
