Bevacizumab therapy and multimodal ultrawide-field imaging in immunogammopathy maculopathy secondary to Waldenström's macroglobulinemia.

Waldenström's macroglobulinemia (WM) is associated with retinal findings of hyperviscosity, such as venous dilation, and findings of immunogammopathy maculopathy, such as serous macular detachment. This report describes a case of bilateral serous macular detachment with intraretinal schisis-like fluid in a patient with WM. Enhanced depth imaging optical coherence tomography revealed a thickened choroid with hyperreflective accumulations in the retinal pigment epithelium layer. Ultrawide-field fundus autofluorescence demonstrated a central area of hyperautofluorescence corresponding to the area of serous macular detachment. Ultrawide-field fluorescein angiography was characteristically silent. Intravitreal bevacizumab therapy resulted in significant reduction in intraretinal fluid but minimal change in subretinal fluid. Long-term follow-up demonstrated alterations in retinal architecture and improved serous detachments.
