Abstract | The purpose of this study is to investigate the response of a porcine corneal organ cultures to the riboflavin/UV-A phototherapy in the injury healing of induced lesions. A porcine corneal organ culture model has been established. Corneal alterations in the stroma were valuated setting an assay system, based on an automated image analysis method able to quantify the damaged (brightness values), within of the 24 regions of interest (ROIs) in which the corneal section has been divided and integrating the data analysis with a multi-aspect approach. Three group of corneas have been analyzed: (healthy, injured and injured-and-treated group). Our study revealed a significant effect of the riboflavin/UV-A phototherapy in the injury healing of porcine corneas after induced lesions. The injured corneas had significant differences of brightness values in comparison to treated (p< 0.00) and healthy (p<0.001) corneas whereas the treated and healthy corneas showed not significant difference (p = 0.995). Riboflavin/UV-A phototherapy shows a significant effect in the restoring the brightness values of damaged corneas to the values of healthy corneas, suggesting treatment restores the injury healing of corneas after lesions. Our assay system may be compared to clinical diagnostic method such as the OCT imaging for in vivo damaged ocular structures investigations. |
