Multimodal imaging of two cases of retinal vein occlusion secondary to Waldenstrom macroglobulinemia

Description
Summary:Purpose: To report multimodal imaging characteristics of two cases of retinal vein occlusion (RVO) secondary to Waldenstrom macroglobulinemia (WM). Case report: Case 1: An 82-year-old woman presented with vision loss. She had a history of WM. Best-corrected visual acuity (BCVA) was 20/100 Snellen equivalent in the right eye (OD) and 20/63 in the left eye (OS). Fundoscopy showed bilateral hemorrhages in posterior pole and along superotemporal arcade. Fluorescein angiography illustrated no macular leakage. Optical coherence tomography (OCT) revealed macular edema (ME). Optical coherence tomography angiography (OCTA) demonstrated abnormalities in choriocapillaris. A diagnosis of bilateral branch RVO was made and ME was treated with intravitreal dexamethasone, achieving stability. Case 2: A 65-year-old man presented with venous dilation, tortuosity, and intraretinal hemorrhages. BCVA was 20/20 in both eyes (OU). OCT showed ME and hyperreflective dots in choroid. A diagnosis of bilateral central RVO was made. Laboratory evaluation and bone narrow biopsy confirmed a diagnosis of WM. After that, our patient consulted because of vision loss. BCVA was 20/400 in OU. Fundoscopy and OCT demonstrated a worsening of the intraretinal hemorrhages and the ME. OCTA showed damage of choriocapillaris. Thus, intravitreal dexamethasone and plasmapheresis was advised. Two months after, BCVA was 20/40 in the OD and 20/32 in the OS. Also, fundoscopy and OCT improved. Conclusion: Early treatment of WM is truly important, with the aim of achieving a decrease in IgM levels in order to avoid toxic effect over the RPE that results in refractory ME.
