Uveitis characteristics and multiple sclerosis phenotype of patients with multiple sclerosis-associated uveitis: A systematic review and meta-analysis
Abstract
PURPOSE: To summarize and meta-analyze uveitis characteristics and multiple sclerosis (MS) phenotype of patients with multiple sclerosis-associated uveitis (MSAU) within a systematic review and meta-analysis.
METHODS: A comprehensive literature search was performed on January 25, 2023, utilizing PubMed, Embase, and Virtual Health Library (VHL) databases. We included studies involving patients with MSAU, such as case series with over 10 patients, cross-sectional, case-control, and cohort studies. Quality and risk of bias were assessed using CLARITY tools and validated metrics like the Hoy et al. and Hassan Murad et al. tools. The pooled analysis focused on 1) uveitis characteristics, 2) ocular complications, 3) MS phenotype, and 3) administered treatments for uveitis and MS. Gender-based subgroup analysis was conducted across continents; heterogeneity was measured using the I2 statistic. Statistical analysis was performed using R software version 4.3.1. The study was registered in PROSPERO with CRD42023453495 number.
RESULTS: Thirty-six studies were analyzed (24 with a low risk of bias, 8 with some concerns, and 4 with a high risk of bias), including 1,257 patients and 2,034 eyes with MSAU. The pooled analysis showed a mean age of 38.2 ± 12.1 years with a notable female predominance (67%, 95% CI [59%-73%]). MS before uveitis was seen in 59% of the cases (95% CI [48%-69%]), while uveitis was present before MS in 38% (95% CI [30%-48%]). The mean age for the first uveitis…
