RESUMO
PURPOSE: Human T-cell lymphotrophic virus type 1 is a RNA retrovirus that primarily affects CD4+ T-cells. Human T-cell lymphotrophic virus type 1 infection is the established cause of adult T-cell leukemia/lymphoma, an aggressive malignancy of CD4+ T-cells, and two nonneoplastic conditions: human T-cell lymphotrophic virus type 1-associated myelopathy/tropical spastic paraparesis and human T-cell lymphotrophic virus type 1 uveitis. Other reported ophthalmic manifestations of human T-cell lymphotrophic virus type 1 infection include lymphomatous and leukemic infiltrates in the eye and ocular adnexa in patients with adult T-cell leukemia/lymphoma, retinal pigmentary degeneration, and neuro-ophthalmic disorders in patients with human T-cell lymphotrophic virus type 1-associated myelopathy/tropical spastic paraparesis and keratoconjunctivitis sicca, episcleritis, and sclerouveitis in asymptomatic human T-cell lymphotrophic virus type 1 carriers. This report describes the ocular findings in three Jamaican patients with human T-cell lymphotrophic virus type 1 infection and adult T-cell leukemia/lymphoma. METHODS: The clinical records of three patients with human T-cell lymphotrophic virus type 1 infection and adult T-cell leukemia/lymphoma examined at the National Eye Institute were reviewed. Each patient had one or more complete ophthalmic evaluations. RESULTS: All three patients had corneal abnormalities, including corneal haze and central opacities with thinning; bilateral immunoprotein keratopathy; and peripheral corneal thinning, scarring, and neovascularization. All three patients had elevated serum immunoglobulin levels. CONCLUSIONS: We believe that the novel corneal findings in these patients are most likely a consequence of the hypergammaglobulinemia induced by the human T-cell lymphotrophic virus type 1 infection or the T-cell malignancy.
