Frequently Asked Questions

What are the common causes of corneal neovascularization?

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

How is corneal neovascularization treated?

Treatment options may include anti-VEGF injections, topical medications, and surgical interventions such as penetrating keratoplasty.

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 the cornea.
