Modified Kuhnt-Szymanowski surgical procedure for secondary cicatricial ectropion in a horse.

The research discusses a successful application of a modified Kuhnt-Szymanowski eye surgery on a 1-year-old gelding for correcting a condition caused by an improperly healed wound on its lower eyelid; the procedure not only corrected the issue, but also led to significant cosmetic and functional improvement without any recurrence of related health issues in the following 18 months.

Background and Problem Statement

• The focal point of this study is a 1-year-old Dutch Warmblood gelding horse that was presented with a case of cicatricial ectropion. This is a condition where the eyelid is turned out, not functioning properly.
• This was caused by a laceration of the right lower eyelid that was primarily treated by a different veterinarian. However, the horse removed the sutures prematurely and the wound ended up healing incorrectly, leading to an inverted eyelid margin.
• This mended wound eventually caused the condition of cicatricial (scarred) ectropion. A corneal ulcer was formed in the right eye due to the exposure caused by the non-functional lower eyelid.

Proposed Solution and Procedure

• To resolve this issue, a modified Kuhnt-Szymanowski surgical procedure, a common operation for correcting eyelid malformations, was planned.
• This procedure primarily involves correcting the ectropion, an abnormal turning out of the eyelid, and repairing the eyelid’s margin with precise surgical methods.

Results and Outcome

• The surgical procedure was successful, leading to improved cosmetic symmetry and functional capabilities.
• The eyelid healed appropriately post surgery without any known complications or issues.
• Importantly, there was no recurrence of corneal ulcers in the right eye in the 18 months following the corrective surgery, providing strong evidence of the procedure’s effectiveness and longevity.
