Successful delivery of subretinal aflibercept (new surgical technique) for the treatment of submacular hemorrhage in idiopathic polypoidal choroidal vasculopathy

Abstract

Submacular hemorrhage (SMH) is often a result of trauma, wet age-related macular degeneration or IPCV and frequently leads to blindness secondary to extreme toxicity of hemoglobin products on photoreceptors. We describe a new technique of subretinal af libercept injection during pars plana vitrectomy for the treatment of SMH in idiopathic polypoidal choroidal vasculopathy (IPCV). A 55-old male presented with sudden loss of vision (HM) secondary to massive subretinal hemorrhage associated with IPCV. Subretinal injection of af libercept with a 25 g/42 g cannula coupled to the viscous f luid control unit of a standard vitrectomy system was performed during parsplana vitrectomy. Controlled injection of af libercept intra-operatively has resulted in a resolution of SMH (confirmed with OCT and ICG). Visual acuity improved from HM to 20/20. This combined approach delivered anti-VEGF agent to target tissue in controlled fashion with the assistance of VFC system (similar to gene therapy) and restored full vision with resolution of SMH.
