*　　　　 The optic nerve and associated vessels are clamped and ligated and transected. *　　　　 *　　　　 Conjunctiva and Tenons capsule are sutured with 3-0 chromic gut or Vicryl, and the skin is closed with simple interrupted sutures of a nonabsorbable material appropriate for the size and environment of the patient *　　　　 六、眼睑损伤的修复 *　　　　 Wound after debridement and ready for suturing. *　　　　 The conjunctiva is sutured with 6-0 Vicryl in a simple, continuous pattern. *　　　　 The marginal suture is placed first, in two separate bites. *　　　　 The second bite. *　　　　 The marginal suture is carefully tied to ensure apposition of the margins. The knot lies along the margin. The wound is sutured with simple interrupted suture of 6-0 silk. The first suture beneath the margin relieves tension on the marginal suture. *　　　　 The wound sutured. *　　　　 A figure-eight suture pattern may be used in place of the first two sutures. *　　　　 The wound sutured using a figure-eight technique. *　　　　 谢 谢 大 家！ *　　　　 *　　　　 *　　　　 4.止血钳暂不松开，用烧烙法止血，其方法为：将注射针头在酒精灯上烧红后，立即用针头烧烙而使出血点止血。松开止血钳（图3-8），用3%氯霉素眼药水点入患眼结膜囊内，松解保定。 图3-8 松解止血钳，手术完毕 【术后护理】术后3天内应用3%氯霉素眼药水滴眼，每天3～4次。手术效果良好 。 *　　　　 四、Excision of Eyelid Tumors Eyelid tumors are common in the dog.

Less commonly found are adenocarcinomas,melanomas and papillomas. *　　　　 The tarsal gland adenoma, as with most tumors of the canine eyelid,is clinically benign,and surgical excision is usually curative. Cryosurgery using 1iquid nitrogen at -20℃ can also be used to treat these tumors. *　　　　 【surgical method】 *　　　　 As the conjunctiva is not involved, it is not removed. Incisions are outlined by dotted lines. The incisions are marked on the patient with a plastic surgery marking pen. The vertical sides of the triangles are 20 per cent longer than the vertical incisions adjacent to the tumor to allow for wound contraction. *　　　　 *　　　　 A square or rectangular in
