Exogenous Methicillin-Resistant Endophthalmitis is Caused by Multidrug-Resistant Lineages that are Associated with Poor Outcomes.

Purpose: To investigate the genomic epidemiology of methicillin-resistant (MRSA) endophthalmitis and correlate it with the presenting clinical features and outcomes.

Methods: Nine patients presenting with MRSA endophthalmitis from 2014 to 2022 were included. Phenotypic and genomic tests were used for strain characterization.
