Supported by the Department of Medical Services of the Ministry of Public Health of Thailand, the 3rd APTOS Big Data Competition focuses on the report generation from fundus fluorescein angiography (FFA) images of over 1,700 patients with different eye conditions.


Fundus fluorescein angiography (FFA) is an invasive diagnostic procedure that helps to assess the anatomy, physiology, and pathology of retinal and choroidal circulation. It aids in the diagnosis of various ocular pathologies and contributes to decision-making when planning the management of ocular pathology.
In this synchronous competition, you’ll build a machine learning model to generate comprehensive angiography reports for patients with eye diseases. You’ll work with over 50,000 FFA images collected in hospital settings to identify different vascular lesions, anomalies, blood flow patterns and to ultimately generate an accurate report, which is a time-consuming and knowledge-intensive task for the physician. If successful, you will help ophthalmologists save tremendous time that can otherwise be spent on improving the quality of patient care.
