    Abstract:
    PURPOSE: To describe the ophthalmologic features observed in patients infected by the human T-cell lymphotropic virus, type 1 (HTLV-1) in Martinique (French West Indies). DESIGN: Prospective consecutive observational case series. METHODS: A complete ophthalmic examination was performed. PATIENTS: Of 200 patients infected by HTLV-1, 77 (38.5%) were seropositive and 123 (61.5%) had HTLV-1 associated myelopathy/tropical spastic paraparesis (HAM/TSP). RESULTS: Uveitis was found in 29 cases (14.5%). Symptoms were mild and the uveitis had little effect on visual function. Ten cases of uveitis were discovered through a systematic examination and had no ocular symptoms. Most of the uveitis was anterior or intermediate. The lesions responded to corticosteroid therapy, but tended to recur. Keratoconjunctivitis sicca existed in 74 patients (37%), accompanied by lymphoplasmocytoid infiltration of the secondary salivary glands rated 3 or 4 on the Chisholm scale in nearly 50% of cases. Corneal alterations were observed in 20 cases (10%), and alterations in the retinal pigment epithelium in 3 cases. CONCLUSION: The three types of ocular affections seen most frequently were uveitis, keratoconjunctivitis sicca, and interstitial keratitis. In patients with HAM/TSP, uveitis was more frequent among younger patients, patients with earlier onset of HAM/TSP, and patients with severe motor disability. Because uveitis is related to a high intrathecal production of immunoglobulin, it could represent a marker for severity of HTLV-1 infection with respect to the course of HAM/TSP. The sicca syndrome related to HTLV-1 virus differs from primary or secondary Sjögren syndrome, because it does not reveal any of the immunologic anomalies generally seen in this disease. Interstitial keratitis was more frequent among patients with HAM/TSP who had high proviral DNA levels.
