Subconjunctival enucleation with or without third eyelid removal may present a viable enucleation technique in rabbits: 18 cases (2014-2022).

OBJECTIVE

To evaluate intraoperative and postoperative complications and outcomes following subconjunctival enucleations with and without third eyelid removal in domestic rabbits.

ANIMALS

18 client-owned rabbits with ocular disease confined to the globe that underwent 20 subconjunctival enucleation procedures at a veterinary teaching hospital.

METHODS

Records were retrospectively reviewed for all enucleations performed at a veterinary teaching hospital from 2014 to 2022. A standard subconjunctival enucleation procedure was performed in all cases, with third eyelid removal in 2 surgeries and without third eyelid removal in the remaining 18 surgeries. Outcomes were assessed on the basis of observations in medical records and owner follow-up.

RESULTS

20 total enucleations were included. Reported reasons for enucleation included suspected or confirmed ocular Encephalitozoon cuniculi infection in 9 rabbits, refractory glaucoma in 4 rabbits, and various intraocular diseases in 5 rabbits. The only intraoperative complication reported was hemorrhage during the third eyelid removal in 1 surgery. Postoperative complications included serous to mucoid discharge from the surgical site in 8 of 20 surgeries and swelling at the surgery site in 2 of the 8 cases that had discharge. Postoperative swelling spontaneously resolved within 3 months of surgery; postoperative discharge spontaneously resolved within 10 months of surgery.

CLINICAL RELEVANCE

Subconjunctival enucleation with or without third eyelid removal in rabbits may be a viable enucleation technique to reduce the risk for intraoperative hemorrhage, but it can result in postoperative complications, including transient discharge and swelling at the surgical site.
