Abstract
Background: The most common ocular symptom of monoclonal gammopathy is the appearance of corneal opacities. Our goal is to present a case with successful haematological treatment of monoclonal gammopathy with ocular significance (MGOS).
Case Report: Our patient was diagnosed with MGOS, with increasing corneal opacification and decreasing visual acuity. Following 4 cycles of plasma-cell-directed bortezomib and dexamethasone treatment (1,3mg/m2 bortezomib subcutaneously and 20 mg dexamethasone orally), most of the corneal opacities disappeared or decreased in size and best corrected visual acuity of the patient increased.
Conclusion: In summary, in monoclonal gammopathy with ocular significance, plasma-cell-directed bortezomib-dexamethasone treatment may successfully decrease or diminish MGOS. The mechanism of corneal opacification and its disappearance has to be further analysed.
