What International Society of Ocular Oncology does

The International Society of Ocular Oncology (ISOO) is a non-profit professional medical society incorporated in Pennsylvania, USA in 2004 and headquartered in Fremont, Wisconsin, dedicated exclusively to ocular oncology, the diagnosis and treatment of tumors of the eyelids, conjunctiva, intraocular structures, and orbit. ISOO connects 600+ clinicians, researchers, and scientists across 68 countries and six continents through a portfolio of membership-based programs anchored by a biennial in-person congress (Athens 2028, Singapore 2030, Miami 2032), an alternating-year virtual congress that drew more than 1,500 participants from 132 countries in 2025, quarterly webinar series, the Ocular Oncology and Pathology Grand Rounds with Cleveland Clinic CME credit, and the YOOG and WOO committees for early-career and women specialists. The society runs six membership categories (Ordinary, Member-in-Training, Collaborating, Allied, Emeritus, Honorary) at a uniform $150 annual dues rate, awards 100+ named travel grants annually to members in training and colleagues in low- and middle-income countries, and operates a Global Twinning Program that pairs ocular-oncology centers across income settings. Supporting offerings include a Collaborative Research Program, the ISOO Collaborations Framework for structured event partnerships, and free member access to the Ocular Oncology and Pathology journal published by Karger. Revenue is generated from membership dues, congress and virtual congress registration fees, and program-related fees; the society has no parent company, subsidiaries, or disclosed investors and is governed by an elected Board of Directors (2026-2028 term).

Recent moves9 records

Expansion highlights6 records

Broad incumbents

• American Academy of Ophthalmology (AAO): The largest U.S. professional society for ophthalmologists. Broad incumbent that encompasses ocular oncology as a subspecialty track and competes with ISOO for member dues and meeting attention.
• European Society for Medical Oncology (ESMO): Leading European professional society for medical oncology. Broad incumbent whose congress and journal ecosystem overlaps with ocular oncology clinicians treating uveal melanoma and other ocular cancers.
• American Society of Clinical Oncology (ASCO): Largest global oncology professional society covering medical, radiation, and surgical oncology. Broad incumbent that increasingly includes ocular oncology sessions and competes for industry sponsorship that could otherwise flow to ISOO.
• International Council of Ophthalmology (ICO): Global umbrella body for ophthalmology societies and ophthalmologic education. Broad incumbent representing national societies worldwide that ISOO members also engage with.
• European Society of Ophthalmology (SOE): Pan-European ophthalmology professional society covering all subspecialties including ocular oncology. Broad incumbent whose congress programming overlaps with ISOO's biennial meetings.

Regional players

• European Retinoblastoma Group (EURbG): European clinical network coordinating retinoblastoma treatment and research across European centers. Regional player with overlapping retinoblastoma mission but narrower geographic remit than ISOO.

Direct peers

• American Association of Ophthalmic Oncologists and Pathologists (AAOOP): North American professional society for ophthalmic oncology and pathology. Direct peer as it serves the same subspecialty clinicians and is an active ISOO partner on the YOOG webinar series and Young Specialists programs.
• International Society of Paediatric Oncology (SIOP): Global professional society for pediatric oncology. Direct peer as it shares overlapping membership for retinoblastoma care and is the formal strategic alliance partner of ISOO under the 2025 retinoblastoma initiative.

Others

• International Agency for Research on Cancer (IARC/WHO): WHO's specialized cancer research agency. Adjacent ecosystem player rather than direct competitor; ISOO engages with WHO advocacy through SIOP, making IARC a relevant peer for governance and policy interaction.

Emerging players

• Ocular Melanoma Foundation (OMF): Patient advocacy nonprofit focused on ocular melanoma. Emerging player in the same disease area as ISOO but serving patients and families rather than clinicians, with potential partnership or awareness-amplification overlap.
