Which of the following can contribute to corneal neovascularization?

Explanation:
Corneal neovascularization arises when the cornea experiences hypoxia or inflammation. The cornea is normally avascular to stay clear, but stress such as edema from endothelial dysfunction signals the tissue to release pro-angiogenic factors like VEGF. Those signals draw blood vessels in from the limbus into the cornea, leading to new vessel growth. Edema reflects a stressed, low-oxygen environment and inflammation, which together promote this neovascular process. In contrast, having adequate tear film oxygen, a normal ocular surface, or a cataract-related change in the lens does not create the conditions that drive new corneal vessels.
