Human Tears Reveal Insights into Corneal Neovascularization
Corneal neovascularization results from the encroachment of blood vessels from the surrounding conjunctiva onto the normally avascular cornea. The aim of this study is to identify factors in human tears that are involved in development and/or maintenance of corneal neovascularization in humans. This could allow development of diagnostic tools for monitoring corneal neovascularization and combin...
متن کاملContribution of Corneal Neovascularization to Dendritic Cell Migration into the Central Area during Human Corneal Infection
Compared with the peripheral corneal limbus, the human central cornea lacks blood vessels, which is responsible for its immunologically privileged status and high transparency. Dendritic cells (DCs) are present in the central avascular area of inflamed corneas, but the mechanisms of their migration to this location are poorly understood. Here, we investigated the contribution of vessel formatio...
متن کاملSubstance P Modulation of Human and Murine Corneal Neovascularization.
Purpose The purpose of this study was to investigate the role of substance P (SP) in patients affected with corneal neovascularization (CNV) and in three different Tac1-knockout (KO) murine models of CNV. Methods SP levels in tears were measured with a multiplex bead assay. The extent of human CNV was quantified as number of affected corneal quadrants. Murine CNV was induced in both strains b...
متن کاملTherapeutic approaches for corneal neovascularization
Angiogenesis refers to new blood vessels that originate from pre-existing vascular structures. Corneal neovascularization which can lead to compromised visual acuity occurs in a wide variety of corneal pathologies. A large subset of measures has been advocated to prevent and/or treat corneal neovascularization with varying degrees of success. These approaches include topical corticosteroid admi...
متن کاملCorneal Neovascularization: A Translational Perspective
Corneal neovascularization (CNV) results from the growth of new vessels from the limbal vasculature into the normally avascular cornea. As the second cause of severe visual impairment worldwide, it represents a major clinical problem. This occurs because CNV often leads to corneal opacification, thus reducing visual acuity. CNV is a well characterized and complex process, which includes differe...
