BACKGROUND: We summarize the history of individuals with Sturge-Weber syndrome (SWS) to inform clinical trial design and identify variations in care. METHODS: We performed retrospective chart review of individuals with SWS from centers in New York City. We characterized data quality using a novel scoring system. For 13 clinical concepts, we evaluated if data were present and if they were of high quality. RESULTS: We included 26 individuals with SWS (58% female; median age at initial visit 7 years; absolute range 1 month to 56 years]). Twenty-two had nevus flammeus, 13 glaucoma, four homonymous hemianopia, and 15 hemiparesis. Nineteen of 21 had at least one confirmed seizure with a known first seizure date, all before 24 months. Most (18 of 26, 69%) epilepsy was controlled. A plurality (10 of 23, 43%) had either normal cognitive function or mild cognitive delays. Aspirin use varied by site (P = 0.02)-at four sites, use was 0% (zero of three), 0% (zero of four), 80% (four of five), and 64% (nine of 14). Data were present for more than 75% of cases for 11 of 13 clinical concepts (missing: age of diagnosis, age of glaucoma onset). There were gaps in level of detail for motor impairments, glaucoma severity, seizure history, cognition, and medication history. CONCLUSIONS: Clinical charts have important gaps in the level of detail around core SWS clinical features, limiting value for some natural history studies. Any clinical trial in SWS designed to prevent epilepsy should begin in the first year of life. Variations in use of aspirin suggest de facto clinical equipoise and warrant a comparative effectiveness study.
