PURPOSE To describe the evaluation of optical coherence tomography (OCT) scans in the Muliticenter Uveitis Steroid Treatment (MUST) trial and report baseline OCT features of enrolled participants.
METHODS Time-domain OCTs acquired by certified photographers using a standardized scan protocol were evaluated at a reading center. Accuracy of retinal thickness data was confirmed with quality evaluation, and caliper measurement of centerpoint thickness (CPT) was performed when retinal thickness data were unreliable. Morphological evaluation included cysts, subretinal fluid, epiretinal membranes (ERMs), and vitreomacular traction.
RESULTS Of the 453 OCTs evaluated, automated retinal thickness was accurate in 69.5% of scans, caliper measurement was performed in 26%, and 4% were ungradable. Intraclass correlation was.98 for reproducibility of caliper measurement. Macular edema (centerpoint thickness ≥ 240 μm) was present in 36%. Cysts were present in 36.6% of scans and ERMs in 27.8%, predominantly central. Intergrader agreement ranged from 78 to 82% for morphological features.
CONCLUSION Retinal thickness data can be retrieved in a majority of OCT scans in clinical trial submissions for uveitis studies. Small cysts and ERMs involving the center are common in intermediate and posterior/panuveitis requiring systemic corticosteroid therapy.
