Japanese researchers have developed an artificial intelligence (AI) tool that objectively assesses the severity of atopic dermatitis (AD) using user-uploaded photographs. The study published in the journal Allergy marks a significant advancement in the application of AI to chronic inflammatory dermatoses.

To develop the AI model, three algorithms were trained and integrated: Body part detection, skin lesion detection, and severity assessment. The latter is based on the Three-Item Severity (TIS) score, a localized severity assessment ranging from 0-9, evaluating erythema, edema or papulation, and excoriation.

Training relied on an extensive database from Atopiyo, the largest online AD platform, which allows 28,000+ users to share 57,000+ photos and comments about their symptoms, provi
