Properties and clinical utility of topotecan fluorescence: Uses for retinoblastoma

Topotecan fluoresces when exposed to ultraviolet (UV) light. Our observations with UV light in retinoblastoma cases has allowed us to minimise and manage inadvertent skin contact, guide periocular injections and leakage from such injections and document conjunctival contact after periocular injection in addition to demonstrating the drug in the vitreous after intravitreal injection. The technique is safe, inexpensive and easy to perform.Fil: Francis, Jasmine H.. Memorial Sloan Kettering Cancer Center; Estados Unidos.
