Diagnostic delay leads to advanced forms of retinoblastoma, compromising survival. The aim of this study was to evaluate the knowledge of health professionals regarding this disease. This survey was carried out among health professionals in the Democratic Republic of the Congo (cities of Lubumbashi, Bukavu and Kinshasa) and Côte d'Ivoire (Abidjan). Health professionals were divided into 3 professional categories: 1) paediatricians and ophthalmologists, 2) other medical doctors, and 3) paramedics. A questionnaire adapted to each category was used. The response to each question was graded as correct or incorrect. Total knowledge of retinoblastoma for the entire questionnaire was evaluated according to a level of overall score for each health professional: score<50% was considered very insufficient, score between 50 and 75% as insufficient and score ≥75% as sufficient. Descriptive statistical analyses and association measurements were performed. A total of 637 health professionals were surveyed, including 69 in the “pediatricians and ophthalmologists” category, 180 in the “others medical doctors” category and 388 in the “paramedics” category. Globally, more than 90% of health professionals did not answer all the questions correctly, and 9% were aware of the most common retinoblastoma-revealing symptoms (leukocoria and strabismus). Overall knowledge of retinoblastoma was sufficient for 26.1% of Paediatricians and Ophtalmologists, 11.7% of Other medical doctors and 2.1% of Paramedicals. One-quarter of health professionals were aware of the two most common signs of retinoblastoma (leukocororia and strabismus) in “pediatricians and ophthalmologists” category, 14% in “others medical doctors” category and 4% in “paramedics” category. Most health professionals surveyed in DRC and Cote d'Ivoire were not aware of the retinoblastoma-revealing symptoms. This certainly contributes to delayed diagnosis and the poor prognosis of this disease in those countries.
