PURPOSE: To report optical coherence tomography findings of choroidal melanoma with subretinal fluid (SRF).
METHODS: Single-center, retrospective review of spectral-domain optical coherence tomography in treatment-naive choroidal melanoma with associated SRF presenting between July 2009 and August 2021.
RESULTS: Of 236 included patients, choroidal melanoma was small (n = 98, 41.5%), medium (n = 99, 41.9%), or large (n = 39, 16.5%). The most common optical coherence tomography feature was ellipsoid zone loss/disruption (n = 174, 73.7%), with unique features of bacillary layer detachment (n = 67, 28.4%), and heterogenous (n = 72, 30.5%) or homogenous (n = 48, 20.3%) subretinal hyperreflective material. Comparison (small vs. medium vs. large) revealed greater SRF extent with increasing tumor size (SRF ≥2 quadrants: 6.1% vs. 27.2% vs. 67.7%, P < 0.001). Ellipsoid zone disruption was less common in small tumors (52.0% vs. 86.9% vs. 94.9%, P < 0.001). Bacillary layer detachment was more common in medium tumors (16.3% vs. 40.4% vs. 28.2%, P < 0.001) and, compared with eyes without bacillary layer detachment, was associated with more SRF (minimal SRF vs. SRF ≥1 quadrant: likelihood ratio 18.8, P < 0.001) and more frequent heterogenous subretinal hyperreflective material (58.2% vs. 19.5%, P < 0.001).
CONCLUSION: Optical coherence tomography features of choroidal melanoma-associated SRF vary by tumor size, with greater SRF extent in larger tumors, less ellipsoid zone disruption in small tumors, and more bacillary layer detachment in medium tumors.
