Children and adults with Neurofibromatosis type 1 (NF1), a common autosomal dominant condition, manifest a variety of ophthalmologic conditions. Plexiform neurofibromas involving the eyelid, orbit, periorbital and facial structures (termed OPPN) can result in significant visual loss in children. Equally important, OPPNs can cause significant alteration in physical appearance secondary to proptosis, ptosis, and facial disfigurement, leading to social embarrassment and decreased self-esteem. Despite NF1 being a relatively common disease in which routine ophthalmologic examinations are required, no formal recommendations for clinical care of children with OPPNs exist. While medical and surgical interventions have been reported, there are no agreed upon criteria for when OPPN require therapy and which treatment produces the best outcome. Since a multi-disciplinary team of specialists (oculofacial plastics, pediatric ophthalmology, neuro-ophthalmology, medical genetics and neuro-oncology) direct management decisions, the absence of a uniform outcome measure that represents visual and or aesthetic sequelae complicates the design of evidence based studies and feasible clinical trials. In September 2013, a multi-disciplinary task force, composed of pediatric practitioners from tertiary care centers experienced in caring for children with OPPN, was convened to address the lack of clinical care guidelines for children with OPPN. This consensus statement provides recommendations for ophthalmologic monitoring and outlines treatment indications, forthcoming biologic therapy, while also discussing challenges to performing clinical trials in this complicated condition.
