Corneal neovascularization (NV) is a sight-threatening condition usually associated with inflammatory or infectious disorders of the ocular surface. It has been shown in the field of cancer angiogenesis research that a balance exists between angiogenic factors (such as fibroblast growth factor and vascular endothelial growth factor) and anti-angiogenic molecules (such as angiostatin, endostatin, or pigment epithelium derived factor) in the cornea. Several inflammatory, infectious, degenerative, and traumatic disorders are associated with corneal NV, in which the balance is tilted towards angiogenesis. The pathogenesis of corneal NV may be influenced by matrix metalloproteinases and other proteolytic enzymes. New medical and surgical treatments, including angiostatic steroids, nonsteroidal inflammatory agents, argon laser photocoagulation, and photodynamic therapy have been effective in animal models to inhibit corneal NV and transiently restore corneal "angiogenic privilege."

Angiogenesis, which usually heralds a poor prognosis for patients, is essential for malignancy. However, this same process is useful in providing a direct and systemic route for the delivery of cytotoxics to the actively growing parts of the tumour. In fact, there is even some merit to stabilising (normalising) the tumour vasculature to aid drug delivery to the deeper recesses of a growing tumour. Additionally, natural biological inhibitors of angiogenesis such as pigment epithelium-derived factor (PEDF) are being developed to test whether they have better activity than older ones such as endostatin. The field of cancer angiogenesis, more than 35 years old now, has seen a few drugs reaching the market, such as Avastin. However, there have been a multitude of failed ones, due to lack of activity, especially when tested in vivo and some failing at clinical trials. This review looks at the current state of play in the area of cancer angiogenesis, and development of therapies to target it.
