Enucleation in a Cownose Ray (Rhinoptera bonasus)

Trauma is a common problem in Cownose Ray during mating season in both wild and captive rays. Enucleation is indicated when there is an ocular trauma. A 5-year-old female Cownose Ray (Rhinoptera bonasus) from Aquaria of Kuala Lumpur Convention Centre (KLCC) was presented to University Veterinary Hospital (UVH), Universiti Putra Malaysia, with a complaint of protruding lef eye, which resulted from crushing into artifcial coral during mating season. Tere were a hyphema in the traumatic lef eye, periorbital tissue tear, exposed lef eye socket, and multiple abrasions on both pectoral fns. Te Cownose was anaesthetized and maintained with isoeugenol and on-feld emergency enucleation of the lef eye was performed. It was managed medically with postoperative enrofoxacin, tobramycin ointment, and povidone iodine. No suture breakdown and secondary infection were observed at day 7 afer enucleation during revisit. At day 24 afer enucleation, the Cownose responded well to treatment with excellent healing progression and no surgical complication was observed.
