Intra-arterial melphalan chemotherapy (IAC) continues to demonstrate excellent utility in the treatment of retinoblastoma. We present the case of a 3-month-old boy diagnosed with with unilateral, advanced stage 5B retinoblastoma and a Coats’ response in the right eye. After laser therapy he received 3 doses of IAC. Intraretinal hemorrhaging, first noted after the second dose and worsening after the third, preceded complex exudative retinal detachment. With little visual potential and evidence of atropy, the eye was enucleated. This case illustrates that intraretinal hemorrhage may serve as an early predictor of treatment failure.
