Return to work following unilateral enucleation in 34 horses (2000–2008)

This retrospective study on 37 horses was conducted to assess long-term complications, scarring, cosmetic appearance and owner satisfaction of horses that underwent transpalpebral enucleation with (n=26) or without (n=11) non-absorbable sutured meshwork prosthesis between 2006 and 2013. Postoperative complications related to the surgery were wound infection, discharge and dehiscence, and no significant difference between groups was found. In one horse, the meshwork had to be removed in order to treat a chronic fistula. Horses with infection or inflammation before surgery were more likely to encounter postoperative complications, whether or not a meshwork was used. Most owners were satisfied by the surgical technique for scarring, but contrary to the present hypothesis, most horses with a meshwork implant had a poor sunken-in appearance, and 26 per cent of owners would like to attempt other techniques to improve the cosmetic result. Also, a further 44 per cent of owners would prefer a better cosmetic result if the technique does not increase complication risk or cost. Meshwork implant prosthesis after transpalpebral enucleation was safe. However, in order to achieve a better cosmetic result, further improvements of the technique will be required.

“…A study reviewing 34 horses of different breeds and a variety of pre-surgical occupations, reported that 12% failed to return to work following unilateral enucleation for reasons related to monocular vision [17]. A large percentage of the population in that study were racing horses (10/34) and 20% of them were not returned to work.…”

BackgroundImplants are often used to improve the cosmetic appearance of horses after enucleation of the eye. When surgical site infection (SSI) occurs, the implant will almost always be lost. The aim of this study is to collect data on the risk factors for SSIs and report long-term follow-up (cosmetic results and return to work) after transpalpebral enucleations. In this retrospective study, records of horses undergoing transpalpebral enucleation were reviewed (2007–2014) and telephone interviews were used to obtain long term follow-up. The potential risk factors for SSIs (indication for enucleation, use of an implant, standing procedures, duration of surgery, opening of the conjunctival sac and prolonged use of antimicrobials) were analysed for their association with the outcome measure ‘SSI’ vs ‘no SSI’ by multivariable binary logistic regression testing. Indications for enucleation were grouped as follows: Group 1 (clean) included equine recurrent uveitis, too small or too large globes, and intraocular tumours, Group 2 (non-clean) included corneal perforation/rupture and infected ulcers and Group 3 (tumour) included extraocular tumours.ResultsOne hundred and seven cases of enucleation were evaluated. An implant was used in 49 horses. The overall number of SSIs was 8 (7.5%). Multivariable logistic regression testing showed implants (OR 7.5, P = 0.04) and standing procedures (OR 12.1; P = 0.03) were significantly associated with the percentage of SSIs and increased the risk of SSI. The eyes of horses in Groups 2 and 3 trended towards a larger risk for developing SSIs (OR 4.9; P = 0.09 and OR 5.9; P = 0.1, respectively). Prolonged use of antimicrobials, long surgery times and the opening of the conjunctival sac during dissection did not show significant associations with SSI risk.ConclusionsThe risk of SSI after enucleation is low in clean eyes and when no implant is used. Placing an implant or performing a standing enucleation significantly increases the risk of SSIs. Although implants can be used for eyes that fall into Groups 2 and 3, 17% of the horses in these two groups developed an SSI leading to loss of the implant.

“…However, it could also be argued that owner perception of surgical outcome and the ability of the horse to continue its intended occupation are quite valuable. This being considered, the authors recognize that even horses with unilateral enucleation have been shown to be able to continue to perform quite well in a variety of occupations . For this purpose, a negatively perceived owner outcome manifested by overt visual impairment is arguably more significant than horses assessed as visual by owners.…”
