Frequently Asked Questions

What are the common causes of corneal neovascularization?

Common causes include chronic inflammation, infection, contact lens wear, and ocular surface diseases.

How is corneal neovascularization treated?

Treatment options may include anti-VEGF injections, topical medications, and in some cases, surgical intervention such as corneal transplantation.

Is corneal neovascularization reversible?

In some cases, if the underlying cause is addressed, neovascularization may regress. However, chronic cases may lead to permanent changes in corneal clarity and vision.
