Regression of aggressive corneal vascularization after photodynamic therapy, subconjunctival Avastin injections and topical cyclosporin-A 1% drops: A case report

Abstract

We describe a case of significant regression of aggressive, deep and superficial corneal vascularization using photodynamic therapy (PDT) with verteporfin, repeated subconjunctival injections of Avastin®, plus topical cyclosporin-A 1% drops. The area of the corneal vascularization was treated with PDT with verteporfin. The subconjunctival space – next to the area of vascularization – was injected with Avastin® (1.25 mg/0.05 ml), immediately after PDT, and then for two more times during the follow-up period. The patient was kept on topical cyclosporin and prednisolone acetate. The outcome was evaluated clinically and photographically for 13 months. Corneal vascularization regressed significantly. No adverse effects were observed, neither locally or systemically. PDT with verteporfin, repeated subconjunctival injections of Avastin®, and topical cyclosporin-A drops appear to be safe and effective in treating aggressive corneal vascularization.
