Vitreous body vessels regressed in mice. The vessels were stained with isolectin B4 alone, FITC alone, and isolectin B4 combined with FITC-dextran by retro-orbital (RO) injection. a: Fluorescence of the vitreous body vessels filled with FITC-dextran (red arrow) or stained with isolectin B4 (yellow arrow) from the P1 samples; b: On P3, the FITC-dextran fluorescence of the vitreous body vessels was slightly reduced (red arrow); c: On P5, the FITC-dextran fluorescence of specific vitreous body vessels was considerably reduced (red arrow); d: The vitreous body vessels (yellow arrow) of OIR-P17 mice could not be fully injected with FITC-dextran. n = 20 from 20 mice.
