Clinical Evaluation of a Novel CRISPR-Cas12a-Based RID-MyC Assay for the Diagnosis of Fungal Endophthalmitis.

Objective: This study evaluated the RID-MyC (Rapid Identification of Mycoses using clustered regularly interspaced short palindromic repeats [CRISPR]) assay, a CRISPR/Cas12a-based diagnostic tool, for its efficacy in diagnosing fungal endophthalmitis (FE) compared with panfungal polymerase chain reaction (PCR) and culture methods.

Design: A comparative cross-sectional study assessing the performance of the RID-MyC assay against established diagnostic modalities for FE.

Subjects: The study included 133 intraocular samples from 117 patients with suspected microbial endophthalmitis.
