The hang-back surgery is a useful technique in the field of strabismus surgery. The aim of this study is to determine the stabilizing effects of fibrin glue as an adjuvant to hang-back surgery.
Four (4)-mm hang-back recessions of the superior rectus muscle was performed in 32 eyes of 16 rabbits. Only in the left eye of the 16 rabbits, fibrin glue was applied between the recessed muscle bed and the sclera at the end of hang-back surgery (fibrin glue group). After 6 weeks, we compared the stability of the recessed rectus muscle between the fibrin glue group and the control group by evaluating the displacement of the muscle.
The frequency of stable insertion of the recessed muscle at the intended site was greater in the fibrin glue group (9 eyes) compared to the control group (3 eyes) (p=0.028). In the control group, 5 eyes showed anterior displacement and 8 eyes showed posterior displacement and in the fibrin glue group, 1 eye showed anterior displacement, and 6 eyes showed posterior displacement. Anterior displacement was more common in the control group (6.3% Vs 31.3%). The control group and the fibrin glue group showed similar histological findings on microscopic examination.
Fibrin glue is effective in stabilizing the new rectus muscle insertion and decreasing the displacement in the hang-back surgery.
后退手术是斜视手术领域的一种有用技术。本研究旨在确定纤维蛋白胶作为后退手术辅助手段的稳定效果。
在 16 只兔子的 32 只眼睛中进行了 4 毫米的上直肌后退。在这 16 只兔子中，只有左眼在后退手术结束时在后退肌肉床和巩膜之间应用纤维蛋白胶（纤维蛋白胶组）。6 周后，通过评估肌肉移位，比较纤维蛋白胶组和对照组后退直肌的稳定性。
纤维蛋白胶组（9 只眼）稳定插入预期部位的频率高于对照组（3 只眼）（p=0.028）。在对照组中，5 只眼出现前移位，8 只眼出现后移位，而在纤维蛋白胶组中，1 只眼出现前移位，6 只眼出现后移位。对照组（6.3%比 31.3%）更常见前移位。对照组和纤维蛋白胶组在显微镜检查下的组织学发现相似。
纤维蛋白胶在稳定新直肌插入和减少后退手术中的移位方面是有效的。
