Entropion eye surgery using Quickert-Rathbun sutures in 10 dogs

Abstract

The objective of this study was to evaluate fornix-based suture placement as a method for entropion correction in the dog. Lower eyelid entropion with resultant trichiasis was corrected in 10 dogs using fornix-based suture placement similar to that employed in the Quickert-Rathbun technique used in man. A double-ended suture was placed originating at the deepest extent of the fornix and exiting the lid 1-2 mm from the eyelid margin. Degree of correction was assessed visually immediately after surgery and at re-examination with a follow-up period of up to 6 months. Fornix-based suture placement led to immediate eversion of the eyelid in each case and thus amelioration of the trichiasis in all dogs. In two cases eyelid eversion initially appeared over-corrected and in two cases exposure of conjunctival tissue was evident initially at the palpebral margin. In all cases, however, such complications were transient with long-term results giving an acceptable apposition between ocular surface and eyelid margin in all adult dogs. In three juvenile dogs on which the technique was used, further surgical treatment was required as the puppies grew. Fornix-based suture placement is a novel approach to entropion correction in the dog which yields acceptable results in the majority of suitable cases without recourse to incisional surgery.
