Uveal effusion in Waldenstrom's macroglobulinemia.

Purpose: To reastport a case of Waldenstrom macroglobulinemia-related choroidal detachments.

Method: Case report.

Results: A 80-year-old woman was referred for bilateral visual loss for few months. She was hospitalized for a Waldenstrom's disease. Both anterior chambers were deep and quiet. Fundus revealed bilateral choroidal detachment without serous retinal detachments. No vitritis, retinal tear or pigmented lesion were observed. After eliminating all other causes of uveal effusion, the patient was treated for her hemopathy with chemotherapy associated with corticosteroids and plasmapheresis. One month later, fundus showed a complete disappearance of choroidal detachments and vision improved.

Conclusion: Uveal effusion is an extremely rare ocular damage of Waldenström disease. As choroidal vessels are porous, they may allow immunoglobulins, over produced, to leak toward supra-choroidal space triggering choroidal detachments.
