Iatrogenic central retinal vein occlusion and hyperviscosity associated with high-dose intravenous immunoglobulin administration

PURPOSE: To describe a patient with iatrogenically induced central retinal vein occlusions secondary to serum hyperviscosity from intravenous immunoglobulin administration. METHOD: Case report. RESULTS: The patient developed bilateral central retinal vein occlusions in association with high dose intravenous immunoglobulins, The central retinal Vein occlusions resolved when the immunoglobulins were withheld and serum hyperviscosity decreased. CONCLUSION: Administration of high dose intravenous immunoglobulins ran be associated with hyperviscosity syndrome manifested by central retinal vein occlusion.
