Mid-peripheral hemorrhages secondary to Waldenström's macroglobulinemia.

Waldenström's macroglobulinemia is a progressive neoplastic syndrome of the reticuloendothelial system and is characterized by the presence of monoclonal IgM paraproteins. The ocular manifestations of macroglobulinemia can include mid-peripheral hemorrhages, sludging of blood in the conjunctival vessels, blurred disc margins, exudates in the fundus and serous retinal detachment. Waldenström's macroglobulinemia and its ocular complications are herein presented.
