Background: Intra-arterial chemotherapy (IA) as a treatment to salvage the eye with advanced retinoblastoma is increasingly utilized based on successes reported by institutions around the world mainly through retrospective studies.

Objective: To study the feasibility of delivering melphalan directly into the ophthalmic artery in a multi-institutional prospective study in children with newly diagnosed unilateral group D retinoblastoma.

Methods: The Children's Oncology Group (COG) initiated study ARET12P1 in 2014 and was open to nine institutions.

Purpose: To evaluate retinoblastoma control after intravenous chemotherapy (chemoreduction) by patient age at presentation.

Design: Retrospective case series.

Methods: This study included 964 eyes of 554 patients treated with chemoreduction at Ocular Oncology Service at Wills Eye Hospital.

Purpose: Intra-arterial chemotherapy (IAC) has emerged as an effective treatment for retinoblastoma (RB) however, little information exists regarding its use in older patients (>5 years). In the present study, we evaluate the use of IAC (2008-2018) for RB in older patients and compare the outcomes to those in the prechemotherapy (<1994) and intravenous chemotherapy (IVC) (1994-2007) eras.

Methods: A retrospective analysis of all patients older than 5 years treated with IAC for RB from 2008-2018.

Purpose: To study changes in the foveal microvascular anatomy using optical coherence tomography angiography (OCTA) after intravenous chemotherapy (IVC) for retinoblastoma (RB).

Methods: A retrospective comparative case-control series included 10 age-matched normal eyes with no documented ocular pathology (control), 10 fellow eyes of patients with unilateral RB treated with IVC (RB fellow), and 10 eyes with extramacular RB in patients with bilateral RB treated with IVC (RB tumor). All eyes were scanned using enhanced depth imaging optical coherence tomography and OCTA.

Purpose: The objective of this study was to compare outcomes after intravenous chemotherapy (IVC) versus intra-arterial chemotherapy (IAC) for unilateral retinoblastoma.

Design: A retrospective comparative interventional case series.

Methods: Patients with unilateral retinoblastoma managed with either IVC using vincristine, etoposide, and carboplatin or IAC using melphalan with or without topotecan with a minimum of 1-year follow-up were compared.

Purpose: Diffuse anterior retinoblastoma is an exquisitely rare variant of retinoblastoma in which the tumor resides in the anterior segment of the eye, without apparent retinal involvement. Previously published cases have been managed with enucleation. We describe globe salvage and visual preservation in 3 consecutive cases using chemotherapy and radiotherapy.

Purpose Of Review: The management of retinoblastoma is complex and involves strategically chosen methods of enucleation, radiotherapy, chemotherapy, laser photocoagulation, thermotherapy, and cryotherapy. Chemotherapy has become the most common eye-sparing modality. There are four routes of delivery of chemotherapy for retinoblastoma, including intravenous, intra-arterial, periocular, and intravitreal techniques.

The management of retinoblastoma has gradually changed over the past 10 years. Over 95% of children with retinoblastoma in the United States are cured with modern techniques. The challenge remains, however, in maintaining the eye and vision.
