Abstract

To investigate whether wide-field multispectral scanning laser ophthalmoscopy could assist in determining depth of chorioretinal pathology in posterior uveitis. Cross-sectional retrospective review of patients with birdshot chorioretinopathy (BCR; 42 eyes of 21 patients) or active primary vitreoretinal lymphoma (PVRL; 18 eyes of 10 patients) who had multispectral wide-field scanning laser ophthalmoscopy (Optos) images. Images acquired with 532 nm and 635 nm lasers were analyzed separately using Optos V Vantage Pro Review software. All 42 eyes with birdshot chorioretinopathy and 8/18 eyes with active primary vitreoretinal lymphoma had lesions on 635 nm imaging, while 26/42 of the birdshot chorioretinopathy eyes and 18/18 eyes with active primary vitreoretinal lymphoma had lesions on 532 nm imaging. The difference between the 2 groups on both 635 nm and 532 nm was statistically significant (P < 0.05). Retinal and choroidal lesions in patients with posterior uveitis can be differentially visualized with Optos 532 nm and 635 nm lasers, respectively, allowing determination of depth of pathology.
