Transpalpebral enucleation using a chain écraseur

Abstract

This study was undertaken to describe the technique, complications and outcome of the use of a chain écraseur for transpalpebral enucleation in horses under general anaesthesia. We report its use in 53 horses, reviewing the subject details, reasons for enucleation, surgical technique, intra-and post operative complications, and long-term outcome. Intraoperative complications included mild to moderate bleeding in 4 horses. Post operative complications included mild periorbital post operative swelling in one horse, transient head tilt in one horse and severe enterocolitis, which resulted in euthanasia in one horse; another 2 horses were subjected to euthanasia after long bone fractures that occurred during recovery from general anaesthesia and 2 horses had the prosthesis removed as a result of inflammatory reaction or infection. Long-term outcome was available for 38 horses, 25 of which returned to their previous activities and 13 were retired. Twelve horses were lost for follow-up. Transpalpebral enucleation using a chain écraseur is a feasible alternative to traditional enucleation techniques that can provide adequate haemostasis during transection of the optic pedicle when used properly.
