A 62-year-old male presented with bilateral metamorphopsia and visual impairment of 6 months' duration. His corrected visual acuity was 0.5 right and 0.3 left. Funduscopy showed exudative retinal visual detachment of about 5 disc diameters in the posterior fundus bilaterally. Both eyes showed engorged retinal veins, retinal hemorrhage and microaneurysms. Detachment of retinal pigment epithelium (RPE) was detected outer to the area of retinal detachment by optical coherence tomography. Laboratory studies showed hyperglobulinemia, leading to the diagnosis of hyperviscosity syndrome due either to primary macroglobulinemia or multiple myeloma. Fluorescein angiography consistently failed to show findings of RPE detachment. This feature appeared to be due to accummulation of viscous abnormal immunoglobulin protein in the sub-RPE space.
