Abstract

Summary: Background: Horses are reported to return to a variety of disciplines following unilateral enucleation; however, owners of horses with ocular disease are frequently reluctant to consider the procedure. There is little published information investigating owners' attitudes towards, and satisfaction following, enucleation. Objectives: To investigate the hypotheses: 1) horses return to their previous level of work following unilateral enucleation and 2) their owners are satisfied with the post‐operative outcome. Study design: Retrospective case series with cross‐sectional survey. Methods: Clinical records from eight equine referral centres in the United Kingdom were reviewed to identify horses that underwent enucleation between August 2006 and March 2015. Owner questionnaires were completed to corroborate information provided by medical records and obtain information on client perceptions. Results: A total of 170 cases were identified and 119 owner questionnaires completed. The most frequent primary uses of horses in the study were pleasure/leisure riding, showjumping and dressage, with 25.2% (n = 30) of horses used for competition. Following enucleation, 77.3% (n = 92) of horses were performing at an equivalent or higher level than prior to enucleation and 60.0% (n = 18/30) of competition horses were competing at an equivalent or higher level. Complications related to the surgical site (predominantly mild post‐operative swelling) were reported in 3.7% of cases and nonocular complications in 3.7% of cases. Of owners who reported being concerned or very concerned about certain factors prior to surgery, ≥86.8% reported that these factors caused little or no issue post‐surgery. Most owners, 90.8% (n = 108) were pleased with the outcome following surgery, with 21.3% (n = 23/108) wishing the procedure had been undertaken sooner. Main limitations: Retrospective data collection from clinical records and the potential for recall bias. Conclusions: Horses can return successfully to a variety of disciplines following enucleation. Owners are satisfied with the outcome and pleased that enucleation was performed.
