Abstract
Sensation over the face was estimated using the Semmes-Weinstein's monofilament (target force 0-05 gms) in a cohort of multi-bacillary (MB) patients whose clinical and ocular characteristics were available at the time of leprosy diagnosis. Among the 190 MB patients examined, 56 (30%) had areas of sensory impairment somewhere on the face and 43 (23%) had sensory deficit over the lids and/or the malar area. Lagophthalmos (adjusted OR 8.96, 95% CI 0.96-83.50), Type 1 reaction (aOR 2.47, 95% CI 1.11-5-52), history of reactions (aOR 6.36, 95% CI 2.40-16.85) and glove and stocking anaesthesia (aOR 3.49, 95% CI 1-40-8.70) were associated with impaired facial sensation. Hypoesthesia restricted to areas over the lids and/or malar area showed a stronger association with lagophthalmos (aOR 17.5, 95% CI 1.98-154.36). Loss of facial sensation appears to be associated with lagophthalmos in MB patients.
