Bevacizumab for the Treatment of Corneal Neovascularization
Summary
The purpose of the current study is to assess the efficacy and safety of the inhibitory effect of bevacizumab (Avastin) with different routes including topical and subconjunctival application on corneal neovascularization in the human eyes.
Description
The compassionate off-label use of bevacizumab as well as the potential risks, benefits, and adverse effects of this medication are discussed extensively with each patient. To further minimize systemic absorption, silicone punctual plugs are placed in the lower eyelids. One group of patients apply topical bevacizumab, 1.0%(10mg/ml), 4 times of day. The other group of patients received subconjunctival injection of bevacizumab(2.5mg/0.1ml) once. The patients are examined at 1day, 1week, 2weeks, 3weeks, and 1month, then monthly till the corneal neovascularization are gone or reduced to some degrees. Best-corrected visual acuity, slip-lamp examination, tonometry, external photography, pachymetry, specular microscopy (if possible), and systemic blood pressure are completed at all visits.

Medical and Biotech [MESH] Definitions
Corneal Neovascularization
New blood vessels originating from the corneal veins and extending from the limbus into the adjacent CORNEAL STROMA. Neovascularization in the superficial and/or deep corneal stroma is a sequel to numerous inflammatory diseases of the ocular anterior segment, such as TRACHOMA, viral interstitial KERATITIS, microbial KERATOCONJUNCTIVITIS, and the immune response elicited by CORNEAL TRANSPLANTATION.
Receptor, Tie-2
A TIE receptor tyrosine kinase that is found almost exclusively on ENDOTHELIAL CELLS. It is required for both normal embryonic vascular development (NEOVASCULARIZATION, PHYSIOLOGIC) and tumor angiogenesis (NEOVASCULARIZATION, PATHOLOGIC).
Corneal Topography
The measurement of curvature and shape of the anterior surface of the cornea using techniques such as keratometry, keratoscopy, photokeratoscopy, profile photography, computer-assisted image processing and videokeratography. This measurement is often applied in the fitting of contact lenses and in diagnosing corneal diseases or corneal changes including keratoconus, which occur after keratotomy and keratoplasty.
Corneal Keratocytes
Fibroblasts which occur in the CORNEAL STROMA.
Corneal Perforation
A puncture or hole through the CORNEAL STROMA resulting from various diseases or trauma.
