ULTRA-WIDEFIELD MULTIMODAL IMAGING OF PRIMARY VITREORETINAL LYMPHOMA

Purpose: To determine the features of primary vitreoretinal lymphoma on multimodal ultra-widefield imaging and correlate these findings to clinical outcomes. Methods: We report a retrospective, observational case series of 43 eyes of 23 patients with biopsy-proven B-cell primary vitreoretinal lymphoma. Fundus photography, fluorescein angiography (FA), optical coherence tomography, fundus autofluorescence, and indocyanine green angiography images were reviewed. Medical records were assessed for the central nervous system involvement and visual acuity outcomes at 6 and 12 months after presentation. Results: Common fundus photography findings were sub-retinal pigment epithelium lesions and vitritis alone. Common ultra-widefield FA findings were vascular leakage and scleral staining. Retinal optical coherence tomography features overlying sub-retinal pigment epithelium lesions or within the macula predicted fluorescence patterns. The presence of retinal fluid or disorganization associated with hyperfluorescence and late leakage. Normal retinal structures associated with hypofluorescence of sub-retinal pigment epithelium lesions or macular leopard spotting on FA and fundus autofluorescence. Peripheral abnormalities noted on ultra-widefield fundus photography, FA, and indocyanine green angiography were more frequent than posterior pole abnormalities. No imaging characteristics predicted time to the central nervous system progression. Conclusion: Ultra-widefield imaging was more informative than posterior pole imaging in fundus photography, FA, and indocyanine green angiography. Common findings on multimodal ultra-widefield imaging may lead to early diagnostic vitrectomy and may reduce the delay in primary vitreoretinal lymphoma diagnosis.
