OBJECTIVE: To describe the imaging characteristics of solitary idiopathic choroiditis (SIC). DESIGN: Retrospective, observational case series. PARTICIPANTS: Ten eyes in 10 patients with SIC. METHODS: Review of chart, fundus photography, ultrasonography, fundus autofluorescence (FAF), infrared reflectance (IR) imaging, and enhanced depth imaging optical coherence tomography (EDI OCT). MAIN OUTCOME MEASURES: Scleral, choroidal, and retinal features of SIC as analyzed by EDI OCT. RESULTS: The mean age at diagnosis was 47 years (range, 7-76 years). There were 4 male patients and 6 female patients. The mean best-corrected visual acuity was 20/25 (range, 20/20-20/150). The SIC lesions were postequatorial (n = 10), with a mean basal diameter of 2.6 mm (range, 1.0-4.0 mm), yellow hue (n = 10), and surrounding orange halo (n = 6). Ultrasonography revealed acoustic solidity (n = 10) with a mean thickness of 1.7 mm (range, 1.4-2.1 mm), FAF disclosed hyperautofluorescence (n = 9), and IR imaging displayed hyperreflectivity (n = 9). On EDI OCT, all 10 lesions were dome shaped with a smooth surface and arose with a gentle slope from the sclera. A more abruptly elevated volcanic configuration was seen in 2 lesions. The overlying choroid was thinned (mean thickness, 32 μm; range, 0-52 μm). The lesions were moderately reflective with an optically bright anterior band and deep shadowing (n = 8). The posterior margin of the lesion could be ascertained in only 1 case. By EDI OCT, the mean diameter was 2942 μm (range, 1887-3809 μm). In no case was there disturbance of the inner retina or subretinal fluid. CONCLUSIONS: Solitary idiopathic choroiditis generally displays ultrasonographic solidity, hyperautofluorescence, and hyperreflectivity on IR imaging. On EDI OCT, the dome-shaped lesion arises from the sclera, outer choroid, or both and the overlying choroidal vasculature is thinned.
