Transpalpebral enucleation using a chain écraseur

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.
