Death by Water: Precautionary Water Submersion for Intravitreal Injection of Retinoblastoma Eyes

Abstract

There is growing interest in intravitreal injections of chemotherapy for retinoblastoma. However, concerns for potential tumor seeding through the needle track has prompted the use of risk-reducing precautionary methods. Presented here is a novel technique, which can be easily replicated, requires minimal sophisticated equipment and with laboratory data supporting its concept. Sterile distilled water submersion for 3 minutes renders retinoblastoma cells nonviable and can be employed as a precautionary method following intravitreal injection in the technique described here.
