Fig. 4From: Minocycline-loaded nHAP/PLGA microspheres for prevention of injury-related corneal angiogenesisChanges in the corneal epithelial injury area over time in different groups after alkali burn. A Typical fluorescein sodium staining of the corneal epithelium was examined at 0, 1, 2,3, 4, 7 days after the corneal alkali burn (scale bar: 3 mm), the percentage of corneal epithelial defect area over time is shown in (B) (n = 6)Back to article page
