PURPOSE: The authors modeled the normally avascular mammalian cornea response to injury by neovascularization. The nature of this process remains obscure, although diffusion mechanisms are thought to be involved.
METHODS: Corneal neovascularization was simulated using fractal stochastic computer models for nonequilibrium diffusion (inverted diffusion limited aggregation) and a stochastic ballistic aggregation.
RESULTS: The inverted diffusion limited aggregation model was found to generate patterns strikingly similar to those observed in pathologic neovascularization of the cornea in vivo.
CONCLUSIONS: This result supports the role of random diffusion mechanisms modified by environmental factors, such as the release of angiogenic factors in corneal angiogenesis.
