PURPOSE: To compare qualitatively and quantitatively Optos fundus camera fluorescein angiographic images of retinal vascular leakage with 9-field montage Topcon fluorescein angiography (FA) images in patients with uveitis. We hypothesized that Optos images reveal more leakage in patients with uveitis. DESIGN: Retrospective, observational case series. METHODS: Images of all patients with uveitis imaged with same-sitting Optos FA and 9-field montage FA during a 9-month period at a single institution (52 eyes of 31 patients) were graded for the total area of retinal vascular leakage. The main outcome measure was area of fluorescein leakage. RESULTS: The area of apparent FA leakage was greater in Optos images than in 9-field montage images (median 22.5 mm(2) vs 4.8 mm(2), P < 0.0001). Of the 49 (45%) eyes with gradable photos, 22 had at least 25% more leakage in the Optos image than in the montage image; 2 (4.1%) had at least 25% less leakage in Optos; and 25 (51%) were similar in the 2 modalities. There were 2 eyes that had no apparent retinal vascular leakage in 9-field montage but were found to have apparent leakage in Optos images. Of the 49 eyes, 23 had posterior pole leakage, and of these, 17 (73.9%) showed more posterior pole leakage in the Optos image. A single 200-degree Optos FA image captured a mean 1.50× the area captured by montage photography. CONCLUSIONS: More retinal vascular pathology, in both the periphery and the posterior pole, is seen with Optos FA in patients with uveitis when compared with 9-field montage. The clinical implications of Optos FA findings have yet to be determined. Published by Elsevier Inc.
