In this paper, we report two cases of a 62-year-old patient presented with blurred vision and a 45-year-old male diagnosed with multiple myeloma who was referred from the Department of Oncology. Slit-lamp examination, in vivo confocal microscopy (IVCM), systemic work-up and serum protein electrophoresis were obtained. In both patients, slit-lamp findings revealed bilateral diffuse subepithelial and anterior stromal crystals and IVCM showed highly reflective deposits in the corneal epithelium and stroma. The first patient was eventually diagnosed with monoclonal gammopathy of undetermined significance following bone marrow biopsy and systemic evaluation. Unusual corneal deposits may constitute the first sign of monoclonal gammopathies. IVCM may be helpful in showing the crystalline nature of the corneal deposits and guiding the clinician to the diagnosis of gammopathies. Both ophthalmologists and oncologists should be aware that corneal deposits may herald a life-threatening hematologic disease.

The cases is presented of a 38 year-old male with a constitutional syndrome, fever, multiple swollen lymph nodes, and hepatosplenomegaly of 2 months onset. There was also mention of headache, bilateral blurred vision, and myiodesopsias. Best correct visual acuity was 20/50 and 20/200. The anterior segment was unremarkable. The fundus of both eyes showed raised and erased discs, accompanied by serous detachment, greater in the left eye. Complementary studies of both eyes showed a visual field with increased blind spot; fluorescein angiography indicated late disc hyperfluorescence. The electroretinogram showed compromise of cones and rods, and the visual evoked potential detected alteration in the perception and conduction of stimuli. The imaging studies were essentially normal. During his hospital admission he presented with paraparesis, renal failure, endocrinopathy, skin alterations, and osteoblastic lesions with negative biopsies. Monoclonal gammopathy was documented, and the diagnosis of POEMS (Polyneuropathy, Organomegaly, Endocrinopathy, Monoclonal gammopathy, and Skin changes) syndrome was made. The chemotherapy started with dexamethasone/melphalan, with a good response at 3 months.
