| Abstract | OBJECTIVE: To determine whether the addition of an unbiased test, metagenomic sequencing of intraocular fluid, compared to standard-of-care diagnostics alone, leads to better patient outcomes in presumed infectious intraocular inflammatory eye diseases. DESIGN: A randomized controlled trial was conducted from May 2022 through February 2024. PARTICIPANTS: Eligible participants had intraocular inflammation concerning for an infectious etiology, were 18 years or older, and had vision better than no light perception (NLP). This study enrolled participants at 6 tertiary referral eye centers in the United States (5 sites) and Thailand (1 site). INTERVENTIONS: Participants were randomized to have their physicians have access to deep sequencing results or not. MAIN OUTCOMES AND MEASURES: The main outcomes were 1) clinical improvement on examination at 4 weeks after randomization and 2) appropriate therapy administered by the treating physician as determined by an independent expert panel. RESULTS: Among the 100 participants enrolled (median [IQR] age, 62.0 [47.5-71.0] years; 57 (57.0%) were women), 92 participants completed the study. Forty-one (41.0%) participants had resolution of inflammation at their 2-week follow-up and 23 (23.0%) participants had a pathogen identified with routine diagnostics and exited the study. Twenty-one (21.0%) participants met the criteria for randomization. At the primary endpoint, 8 (88.9%) patients in the metagenomic sequencing group had clinical improvement compared to 7 (63.6%) patients in the no metagenomic sequencing group (risk difference, 30% [95% CI: 0.6% to 59.1%]; relative risk (RR)=1.35 [95% CI: 1.01 to 1.81]; P=0.045). Eight (88.9%) patients were considered to receive the appropriate therapy in the metagenomic sequencing group compared to 11 (100%) patients in the no metagenomic sequencing group (risk difference, -12.0% [95% CI: -38.0% to 14.0%]; RR= 0.89 [95% CI: 0.68 to 1.15]; P=0.37). There were 3 non-study related adverse events. CONCLUSIONS: Having access to metagenomic sequencing results modestly improved clinical outcomes in a subset of patients with suspected intraocular infections. Larger studies are needed to determine the long-term impact on management and clinical outcomes. TRIAL REGISTRATION: https://clinicaltrials.gov/ct2/show/NCT05286203. |
