Purpose:To evaluate the feasibility of the combined use of bevacizumab (Avastin�) and combined with infliximab (Remicade�) in the treatment of naive choroidal neovascularization (CNV) due to age-related macular degeneration (ARMD) eyes. Methods: Intravitreal injections of bevacizumab combined with infliximab in 6 neovascular ARMD eyes. All patients underwent complete ophthalmologic examination on the initial visit and at days 1, 30, 60, 90, 120, 150 and 180 following the first injection. Optical coherencetomography (OCT) and fluorescein angiography (FA) were performed during at initial visit and monthly during the 6 months follow-up period. Electroretinography was performed before and 30 days after initial injection, in order to evaluate retinal toxicity induced by such treatment. Results: Thirty days after the first injection, 5 eyes (83%) showndecrease in macular thickness. No change was seen in electroretinogram (ERG) in any eyes compared to initially performed electroretinogram. All phakic eyes developed cataract. One patient developed vitritis and was submitted to medical treatment successfully. At the end of the 6 months follow-up period, 4 patients showed significant improvement in the exudative process of choroidal neovascularization (CNV). One eye had mild persistent sub macular fluid without active choroidalneovascularization, and, intraretinal fluid with observed in the remaining eye due to active choroidal neovascularization. Conclusion: The combined use of bevacizumab with infliximab in eyes with neovascular age-related macular degeneration was effective in reducing leakage and improving the macular thickness. However, it?s not possible to assert that the results were related to synergic effects of the combination therapy. A controlled study with morecases is necessary to precisely define the complication rates; however the dosage and/or association of drugs studied in this research shouldn?t be recommended in clinical practice due to cataract as well as inflammatory reaction.
