Abstract

|
Changes in the eye resulting from leprosy include lagophthalmos, ectropion and the eyelid retraction. In lagophthalmos, an interpalpebral gap(lid gap) of 2mm or less, which is most preferred after correction, does not have any adverse effect on the vision. However, a gap of 3mm or greater can cause or make the eye susceptible to the dryness of the cornea or other vision problems. Bell’s phenomenon will adequately prevent eye damages, especially corneal damage when the lid gap is less than 3mm. Although static methods such as autogenous canthal sling, lateral tarsal strip, medial tarsorrhaphy and gold implant had a positive cosmetic effect when used in combination, the lid gap could hardly reduce to less than 3mm. Frequent recurrence of lagophthalmos and ectropion after static methods required further definite surgical treatment. We applied a dynamic method of modified Gillies to correct lagophthalmos and it was successful in reducing the lid gap to less than 2mm in most cases.
