The Japan Eye Genetics Consortium (JEGC) was to establish a large cohort of Japanese patients with IRD in multicenter studies. The clinical and genetic data are stored in JEGC online database (>3000 subjects). This research network expands to the East Asian countries, and the East Asin IRD society (EAIRDs) develops international large cohort studies with large‐scale data sharing.The provision of an accurate diagnosis of IRD is still difficult or unavailable in East Asia due to the limited access to multidisciplinary teams of specialists who can perform specific clinical investigations, including retinal imaging as well as genetic testing, interpretation of genetic results (i.e., genetic diagnosis), and counselling. There are currently few approved treatment approaches for IRD. Thus, it is widely recognized that the development of accurate gene‐specific diagnosis and novel therapeutic interventions is crucial to meet the urgent unmet needs of people suffering from blindness due to IRD.Recently, deep learning techniques have been successfully applied in various medical fields, and the utilization of machine learning‐assisted diagnosis has been extensively promoted. Deep learning based on clinical images has been rapidly developed to predict diagnosis of common ocular disorders such as diabetic retinopathy and age‐related macular degeneration. However, AI‐oriented bioinformatic engineering has never been applied to the clinic of ophthalmic orphan diseases.Therefore, we aim to create a platform of comprehensive patient information and AI‐based diagnostic support in the JEGC/EAIRDs/Japan national hospital organization network. Here, a study design and preliminary data of an AI‐based diagnostic support system are illustrated.
