The corneal pocket assay.

Area of Science:

• Biomedical research
• Ophthalmology
• Vascular biology

Background:

• Continuous in vivo monitoring of neovascularization is essential for developing drugs that modulate angiogenesis.
• The cornea, being initially avascular, offers a unique model for studying blood vessel formation.

Purpose of the Study:

• To describe the avascular cornea assay for in vivo monitoring of neovascular growth.
• To evaluate the assay's utility in assessing angiogenesis suppressors and stimulators.

Main Methods:

• An angiogenesis stimulus is implanted into a corneal micropocket.
• Vascular outgrowth from limbal vasculature into the cornea is induced and monitored.
• The effects of local or systemic anti-angiogenic agents are assessed.

Main Results:

• The cornea assay allows for precise measurement of new blood vessel formation.
• The assay is suitable for evaluating both pro-angiogenic and anti-angiogenic factors.
• Advantages and disadvantages across different species are discussed.

Conclusions:

• The avascular cornea assay is a valuable tool for in vivo angiogenesis research.
• This assay facilitates the development and evaluation of novel therapeutic strategies targeting neovascularization.
