ⓘ Corneal neovascularization

Corneal neovascularization is the in-growth of new blood vessels from the pericorneal plexus into avascular corneal tissue as a result of oxygen deprivation. Maintaining avascularity of the corneal stroma is an important aspect of corneal pathophysiology as it is required for corneal transparency and optimal vision. A decrease in corneal transparency causes visual acuity deterioration. Corneal tissue is avascular in nature and the presence of vascularization, which can be deep or superficial, is always pathologically related.

Of corneal neovascularization is a sight threatening condition which may be caused by inflammation from infection, chemical injury, autoimmune conditions, after corneal transplantation, traumatic and facilities, among other ocular pathologies. Common causes of CNV including trachoma of the cornea, corneal ulcers, keratoconjunctivitis phylctenular, rosacea keratitis, interstitial keratitis, sclerosing keratitis, chemical burns, and contact lens wear over a longer period of time. Surface presentation of the CNV are usually associated with wearing contact lenses while deep presentation may be caused by chronic inflammatory and anterior segment eye diseases.

Of corneal neovascularization is becoming more common worldwide with an estimated frequency of 1.4 million cases per year, according to a study 1998 Massachusetts eye and ear infirmary. The same study showed that tissue from twenty percent of the corneas examined in the course of corneal transplantation had some degree of neovascularization that negatively affect the prognosis in individuals who have had the procedure keratoplasty.
