Abstract

Purpose: To present the multimodal imaging findings of four patients with systemic amyloidosis, renal failure, and chorioretinopathy. Methods: Retrospective analysis of four patients presenting to four institutions with evidence of amyloid induced chorioretinopathy. Fundus photography, autofluorescence, and spectral domain optical coherence tomography findings were studied and are presented. Results: Four patients with biopsy-proven systemic amyloidosis demonstrated progressive chorioretinal degeneration with color fundus photography and autofluorescent imaging. With spectral domain optical coherence tomography analysis, amyloidosisinduced chorioretinopathy was characterized by a widened choriocapillaris band, choroidal infiltration, diffuse photoreceptor dysfunction, and thinning of the outer nuclear layer. Conclusion: Multimodal imaging including spectral domain optical coherence tomography analysis in eyes of patients with systemic amyloidosis shows deposition in the choroid. The deposition may cause a secondary toxic and or barrier effect resulting in diffuse retinal pigment epithelium and photoreceptor dysfunction.
