Résumé
A total of 424 leprosy patients were screened for uveal involvement. Uveal changes were found in 11.2% of these patients. Uveal involvement was more common in patients with greater duration of the disease and in patients on irregular Dapsone therapy. Of the patients with uveal involvement 82% were lepromatous, 16% were borderline and 2% were of tuberculoid leprosy. Uveal changes in form of active iridocyclitis (21.3%), healed iridocyclitis (58.5%), iris atrophy (10.6%), iris pearls (7.4%), small irregular pupil (46.7%), pupil refractory to dilatation (56.3%) were seen. Posterior segment involvement was rare. Lepromatous and borderline leprosy patients with no clinical evidence of uveal involvement had decreased power of accommodation as compared to normal subjects.

The histopathological features in type I (lepra) reaction comprised a loose and disorganised granuloma in the upper and mid-dermis, dermal edema and variable cellular contents, namely, epithelioid cells, lymphocytes, giant cells, and macrophages. While ENL reactions, were characterised by predominant involvement of subcutaneous vessels, vasculitis, and polymorphonuclear infiltration in and around the blood vessels.

Serum zinc, copper, calcium and magnesium levels were estimated by atomic absorption spectrophotometry in 56 leprosy patients comprising 14 BT, 12 BB, 11 BL and 19 LL. These findings were evaluated in comparison to 42 normal subjects serving as controls. A significant elevation of serum copper was recorded while reduction in zinc, calcium and magnesium was noted throughout the leprosy spectrum. The findings of our study are of considerable importance and need to be taken note of in the light of delineating these alterations to be the cause or effect of the disease.

The morphological features of ENL, occurring in histoid leprosy are described. Its infrequent occurrence has been emphasised. The possible immunopathogenesis of its occurrence in histoid leprosy is briefly outlined.
