Technique of lateral canthoplasty for the correction of macropalpebral fissure in the dog.

The various clinical anomalies associated with macropalpebral fissure in the dog can be relatively successfully addressed by a reduction in functional eyelid length and stabilisation of the lateral canthus. In this new technique the basic principles of the Kuhnt-Szymanowski lateral canthoplasty have been extended to include an additional shortening of the upper eyelid obtained by a triangular split thickness resection. Results in a series of 22 patients have demonstrated significant clinical improvement throughout, with optimum positioning of the modified palpebral fissures being achieved in five of these patients by the additional and subsequent resection of redundant forehead skin.
