Conditions
Interventions
Gold Standard:JRS scores independently assessed by two ophthalmologists with =10 years of blepharospasm expertise (intensity 0-4 + frequency 0-4, total score 0-8).
Index test:Multimodal deep learning-based intelligent JRS scoring system (Input: 5-min standardized facial video
Output: JRS score).
