From blink to care: smartphone video–based functional analysis and personalized management in pediatric blepharoptosis

Résumé fourni par la source

Early detection of congenital ptosis is critical to prevent visual and psychosocial impairment in children, yet clinical assessment is challenged by limited patient cooperation and specialist availability. In this prospective, multicenter study, we developed and validated a smartphone-based system comprising three modules: morphological assessment, functional analysis, and a domain-adapted dialogue model, using 3164 blink clips and 1,229 facial images. The morphological module showed high measurement accuracy with intraclass correlation coefficients over 0.90 versus manual assessments. The functional module identified levator dysfunction with an area under the curve of 0.993, achieving robust functional stratification accuracy in both internal (0.91) and real-world (0.89) cohorts. The dialogue model demonstrated improved correctness and applicability over its baseline in addressing ptosis-related queries, achieving overall performance comparable to GPT-4o in expert evaluation and a patient satisfaction score of 4.93/5 in real-world deployment. This smartphone platform enables precise ptosis evaluation with patient-centered interaction, facilitating informed decision-making and personalized care in oculoplastic practice.
