Purpose: This article presents an unusual case of ocular involvement of multiple myeloma masquerading as macular edema associated with diabetic retinopathy.
Methods: A report of a single case.
Results: The presence of concomitant type 2 diabetes and scattered retinal hemorrhages presented a diagnostic challenge. Large globular vitreous opacities and significant weight loss were suggestive of a neoplastic process. We demonstrate multimodal imaging findings that can be associated with plasma cell dyscrasias and also describe the purported mechanism by which plasma cell dyscrasias cause macular edema and exudative retinal detachments.
Conclusion: Although multiple myeloma and related plasma cell dyscrasias are rare causes of ocular disease, they should be considered in the differential diagnosis of recalcitrant macular edema, and there should be a low threshold for systemic evaluation.
Keywords: cystoid macular edema; exudative retinal detachment; macular edema; vitritis.
