Eksperimentel: Anti-VEGF and Immunosuppression
Bevacizumab: Dosage 1.25mg/0.05ml; Frequency monthly injections; Duration at least 3 months. Immunosuppression: cyclosporine and/or azathioprine |
Injection technique: After lid speculum insertion and irrigation of the conjunctiva with 5% povidone-iodine, 0,05ml of bevacizumab will be inserted through the pars plana 3.5mm to 4.0mm posterior to the surgical limbus using a 30 gauge needle.
After injection, topical antibiotics will be immediately applied in the injected eye.
Immunosuppression: Corticosteroids will be prescribed (1mg/Kg/d) with tapering along 5 months.
Immunosuppressive drug of choice is cyclosporine (3-5mg/Kg/d).
In case of contraindication to cyclosporine use, azathioprine or mycophenolate mofetil will be prescribed.
