Corneal neovascularization is the unnecessary ingrowth of blood vessels from the limbal vascular plexus into the cornea, caused by disruption of the balance between angiogenic and antiangiogenic factors that preserves corneal transparency. Immature new blood vessels may lead to lipid exudation, persistent inflammation, and scarring, thus threatening corneal transparency and visual insight. Sometimes in advance stages ingrown blood vessels reach the visual axis cause permanent vision threatening and in patients with corneal grafts, may contribute to rejection.
Review articles are the summary of current state of understanding on a particular research topic. They analyze or discuss research previously published by scientist and academicians rather than reporting novel research results.
Review article comes in the form of systematic reviews and literature reviews and are a form of secondary literature. Systematic reviews determine an objective list of criteria, and find all previously published original research papers that meet the criteria. They then compare the results presented in these papers. Literature reviews, by contrast, provide a summary of what the authors believe are the best and most relevant prior publications.
The concept of "review article" is separate from the concept of peer-reviewed literature. It is possible for a review to be peer-reviewed, and it is possible for a review to be non-peer-reviewed.
