[Intermediate uveitis due to human T-cell lymphotropic virus type 1]

The case of a 66-year-old woman with intermediate uveitis in both eyes and progressive weakness of lower limbs is reported. A human T-lymphotropic virus type 1 (HTLV-1) infection was detected in the serological study, with the patient being diagnosed with tropical spastic paraparesis and HTLV-1 intermediate uveitis. The patient made good progress with oral steroid treatment.

The clinical and epidemiological aspects of HTLV-1 infection are discussed. We recommend a serological determination of the virus in intermediate uveitis of unknown origin in people from endemic areas or with neurological symptoms.
