Registration for the 2026 One Rb World Conference opens in July 2025
The 8th One Rb World Conference will take place immediately before the 58th World Congress of the International Society of Pediatric Oncology, which will be held in San Antonio, September 15-18, 2026.
Welcoming retinoblastoma patients, survivors, family members, medical professionals and scientists, we look forward to sharing three full days of One Rb World programming, community and collaboration in the Lone Star State.
One Rb World 2026 will be hosted by World Eye Cancer Hope USA, organized together with Jesse Berry M.D., Director of Ocular Oncology and Retinoblastoma at Children’s Hospital Los Angeles (CHLA); and Maura Di Nicola M.D., Assistant Professor of Clinical Ophthalmology at Bascom Palmer Eye Institute in Miami, Florida.
We recognize our 2026 conference falls during Rosh Hashana, and we apologize for any conflicts this may create. We hope many in our community will still be able to participate, and we remain committed to making the conference as accessible and inclusive as possible.
Conference Program
Our One Rb World program will take place over three days. We offer a virtual option so our global community can join even if travel to San Antonio is not possible. Local time during the conference will be GMT/UTC -5.
We will discuss aspects of early detection and diagnosis, medical care, psychosocial supports, and survivorship on a local and global scale.
Child Life Program
One Rb World welcomes all patients, survivors, and family members! We are delighted to provide a full program of child life activities on September 12-14 for children diagnosed with retinoblastoma, their siblings, and the children of adult survivors and conference speakers.
The program will be led by Certified Child Life Specialist, Morgan Livingstone, a dedicated member of the WE C Hope team, together with local child life leaders. As well as free play for all ages, planned activities help children explore, understand, and live well with their individual experiences of eye cancer.
Tickets and Registration
We are proud to offer a low registration rate for all family and survivor tickets, and a reduced rate for all attendees from countries classified by the World Bank as Low-Income and Lower-Middle-Income.
Every child attending the child life program must be registered.
Details of virtual registration will be available closer to the event.
