PURPOSE • To evaluate the effect of regression and treatment of subconjunctival and intralesional Bevacizumab (AvastinⓇ) and Ranibizumab (LucentisⓇ) injection on corneal neovascularization (CNV) resulting from different ocular surface disorders
METHODS • Group I - Bevacizumab (AvastinⓇ; Genentech, Inc., San Francisco, CA) - 1.25 mg/0.05cc injection only (n=5) under topical anesthesia • Group II - Ranibizumab (LucentisⓇ ; Genentech, Inc., San Francisco, CA) - 0.5 mg/0.05cc injection only (n=5) under topical anesthesia
METHODS • Charateristics of patients • Patients were followed up at 1, 7, 30 days after treatment. • Used Image J software (Wayne Rasband at the Research Services Branch, National Institute of Mental Health, Bethesda, MD) to analyze the vascularized corneal area.
Results - Area of CNV Bevacizumab 1.25mg/0.05cc injection (Group I) < Post herpetic CNV with corneal opacity > Pre injection Post injection (POD # 7) < Post KP CNV d/t Chemical burn > Pre injection Post injection (POD # 7)
Results - Area of CNV Bevacizumab 1.25mg/0.05cc injection (Group I) < CNV d/t Lipid degeneration > < CNV d/t corneal ulcer > < Post Pterygium OP. > Pre injection Pre injection Pre injection Post injection (POD # 7) Post injection (POD # 7) Post injection (POD # 7)
Results - Area of CNV Bevacizumab 1.25mg/0.05cc injection (Group I) (By using Image J software)
Results - Area of CNV Ranibizumab 0.5mg/0.05cc injection(Group II) < Post KP CNV > Pre injection Post injection (POD # 7) < CNV with corneal opacity d/t Lipid keratopathy > Pre injection Post injection (POD # 7)
Results - Area of CNV Ranibizumab 0.5mg/0.05cc injection (Group II) < Post herpetic CNV with corneal opacity > Pre injection Post injection (POD # 7) < Post herpetic CNV with corneal opacity > Pre injection Post injection (POD # 7)
Results - Area of CNV Ranibizumab 0.5mg/0.05cc injection (Group II) (By using Image J software)
Conclusions & Discussions • Subconjunctival and intralesional Bevacizumab injection effectively regress CNV induced by various causes, whereas there is no significant effect for CNS after Ranibizumab injection. • Bevacizumab injection were seems to be more effective to reduce CNV • than Ranibizumab injection. • Bevacizumab injection showed significant regression of CNV in short • period of time. After one month Bevacizumab injection, CNV had • tendency to recur and re-growth.
Conclusions & Discussions • Subconjunctival and intralesional Bevacizumab injection could be considered a treatment option for the CNVs. • Further research is needed to assess the potential duration, side – effects and minimal effective dose.
