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.
本研究的目的是评估穹窿部缝线植入作为犬睑内翻矫正方法的效果。采用与人 Quickert-Rathbun 技术中类似的穹窿部缝线植入法，对 10 只患有下睑内翻并伴有倒睫的犬进行了矫正。将一根双头缝线从穹窿最深部穿出，在距睑缘 1 - 2 毫米处穿出眼睑。术后立即及随访长达 6 个月复查时，通过肉眼评估矫正程度。基于穹窿部的缝线植入在每例中均导致眼睑立即外翻，从而改善了所有犬的倒睫情况。2 例眼睑外翻最初出现矫正过度，2 例睑缘处结膜组织暴露最初较为明显。然而，在所有病例中，这些并发症都是暂时的，长期结果显示所有成年犬的眼表与睑缘之间的贴合情况均可接受。在 3 只接受该技术治疗的幼犬中，随着幼犬生长，需要进一步手术治疗。基于穹窿部的缝线植入是一种用于犬睑内翻矫正的新方法，在大多数合适的病例中无需进行切开手术即可取得可接受的效果。
