Tocilizumab and Aflibercept as a Treatment Option for Refractory Macular Edema after Acute Retinal Necrosis

Introduction: The inflammatory milieu after acute retinal necrosis (ARN) may lead to a breakdown of the inner and outer blood-retinal barrier and consequently to a cystoid macular edema (CME) with accumulation of intra- and subretinal fluid. Up to now, there is no established therapeutic approach for CME in ARN patients.Case report: We report a case of an immunocompetent 14-year-old female with chronic ARN-related CME, which was unresponsive to valacyclovir, prednisone and intravitreal ranibizumab injections. A combination treatment of tocilizumab, an interleukin-6 receptor inhibitor, and intravitreal aflibercept was successful to control the CME.Conclusion: In selected patients with treatment-refractory CME following ARN a therapy with tocilizumab and intravitreal aflibercept might be considered.
