IMMUNOGLOBULIN-G CRYSTALLINE KERATOPATHY ASSOCIATED WITH MONOCLONAL GAMMOPATHY

Purpose: Two cases of corneal crystal deposition are reported, both ca used by a benign monoclonal gammopathy. Methods: Similar corneal patho logy is identified in these two patients, both of whom presented with visual acuities of 6/6 or better: Consideration of possible causes inv olved biochemical and haematological testing and assessment. Results: Potential for malignant transformation of monoclonal gammopathy was re cognized, hence the need for ongoing haematological follow-up. Conclus ion: Corneal crystals may be the initial presentation in a patient wit h monoclonal gammopathy, a rare, but significant clinical finding.
