Ischemic Necrosis and Atrophy of the Optic Nerve After Periocular Carboplatin Injection for Intraocular Retinoblastoma

Periocular injections of carboplatin may be a useful treatment approach in the management of patients with advanced intraocular retinoblastoma and may minimize systemic side-effects. However, ophthalmologists and pediatric oncologists should be aware of potential marked local complications with periocular carboplatin delivery, including ischemic optic neuropathy. Modifying the injection site/location (for example, subtenon space) or adding other delivery routes adjuncts (for example, fibrin sealant) deserves further study.
