Abstract
The cornea is a clear connective tissue membrane at the front of the outer layer of the eyeball wall. It plays a crucial role in the refractive system of the eyeball, making it essential to maintain its transparency. Neovascularization and lymphangiogenesis in the cornea significantly impact corneal transparency and immune privilege. The growth of corneal neovascularization (CNV) and corneal lymphangiogenesis (CL) vessels is interconnected yet independent. Currently, there is a substantial amount of clinical and experimental research on CNV and CL vessels. However, due to the relatively recent focus on CL vessel research compared with CNV research, most scholars tend to concentrate on CNV, with few articles offering a comprehensive comparison and discussion of the two processes. The present review emphasizes the similarities and differences between CNV and CL and summarizes recent research progress on their correlation in animal models, growth characteristics, cytokine effects and related diseases.
