Slit lamp biomicrographs. Preoperative and postoperative observation of New Zealand rabbits. A One day after alkali burn injury, the boundary was clear in all 3 groups. Seven days after alkali burn injury, corneal neovascularization (CNV) started to appear in the corneal limbal in the two groups (control group and low concentration group). The diameter of the burn wound was reduced 10 days after alkali burn injury in the high concentration group. CNV grew to a large extent 14 days after alkali burn injury in the other two groups. B Fourteen days after alkali burn injury, there was obvious CNV growth into the corneal limbus in the control group. In the low concentration group, the CNV in the corneal limbus was slightly sparser than that in the control group. There was no obvious CNV growth during the observation period 14 days after alkali burn injury
