Corneal neovascularization may result in loss of corneal transparency and blindness. However, developing successful and inexpensive medical treatments for corneal neovascularization remains an unresolved issue. Recently, several studies have implicated miRNA functions in the regulation of cornea homeostasis. This study aimed to identify the miRNA expression profile in the neovascularized cornea...

PURPOSE To evaluate the short-term effects of a single subconjunctival injection of triamcinolone acetonide as an adjunct to subconjunctival bevacizumab for prevention of corneal neovascularization in rats. METHODS Chemical cauterization was performed in the central cornea of the right eye in 48 male Sprague-Dawley rats (4 eyes were excluded due to perforation and/or infection). Immediately a...

Corneal neovascularization is a serious condition that may arise secondary to chemical burns, ischemia, infection, trauma, and inflammation and represents a major cause of blindness. This study investigated the efficacy of topical application of infliximab [tumor necrosis factor-a (TNF-a) monoclonal antibody] in the treatment of corneal neovascularization in the rabbit model.

Macrophages accumulate during the course of corneal neovascularization, but its mechanisms and roles still remain elusive. To address these points, we herein examined corneal neovascularization after alkali injury in mice deficient in fractalkine receptor/CX3CR1, which is normally expressed by macrophages. After alkali injury, the mRNA expression of CX3CR1 was augmented along with accumulation ...

Demand for rigid gas permeable contact lens has increased recently. Many complications including microbial keratitis and corneal neovascularization can be induced by inappropriate management poor hygiene. Despite of the initial education proper management, actual compliance adherence to guideline is significantly low. We reviewed improve hygiene solutions cleaning conditioning lens.

To investigate the effects of loss of transient receptor potential vanilloid receptor 1 (TRPV1) on the development of neovascularization in corneal stroma in mice. Blocking TRPV1 receptor did not affect VEGF-dependent neovascularization in cell culture. Lacking TRPV1 inhibited neovascularization in corneal stroma following cauterization. Immunohistochemistry showed that immunoreactivity for act...

PURPOSE To compare the effects of bevacizumab applied either subconjunctivally or topically, in a rat model of corneal neovascularization induced by alkali burn. METHODS The right corneas of 24 Wistar-Albino rats were cauterized with silver nitrate sticks. The rats were divided randomly and equally into three groups: no treatment control (n=8), subconjunctival bevacizumab treatment (n=8), and...

Corneal avascularity is necessary for the preservation of optimal vision. The cornea maintains a dynamic balance between pro- and antiangiogenic factors that allows it to remain avascular under normal homeostatic conditions; however, corneal avascularity can be compromised by pathologic conditions that negate the cornea's "angiogenic privilege." The clinical relevance of corneal neovascularizat...

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...

Objectives: To determine if Thalidomide has a similar effect in an alkali burn model of corneal neovascularization, we evaluated the effect of Thalidomide on corneal angiogenesis after alkali corneal burns in rabbits. Methods: Twelve rabbits received alkali burns to one cornea. Post injury, four rabbits received oral Thalidomide, 200 mg/kg/day and eight rabbits received placebo (powdered sugar)...
