Ocular findings in leprosy in the United States.

We examined 55 clinic patients with biopsy-proven Hansen's disease and catalogued the ocular findings. Forty patients had lepromatous disease and 15 had tuberculoid disease. Visual acuity was 20/40 or better in 52 patients. Examination of pupillary size in all cases and after dilation with cocaine and hydroxyamphetamine in 15 cases showed decreased sympathetic innervation to the iris dilator muscle in seven cases. Ocular inflammation was uncommon: there was one case of active interstitial keratitis, three of episcleritis, and four of iritis. Although 41 patients had ocular problems attributable to Hansen's disease, the severity of the ocular complications was much less than reported in similar studies from other countries. We believe that the differences were the result of effective antimicrobial and anti-inflammatory therapy.
