Ciliary body non-magnetic foreign body removal

When the eyeball is penetrating, there is often a foreign body in the eyeball. Foreign matter entering the eyeball can be metallic or non-metallic. Metal foreign bodies can be divided into magnetic or non-magnetic. Therefore, when a penetrating injury occurs in the eyeball, it is first necessary to find out whether there is foreign matter in the eye, the nature and position of the foreign matter. The surgical plan can only be developed after the situation has been identified. Treatment of diseases: eyeball perforation, eyeball penetrating injury Indication Ciliary body non-magnetic foreign body extraction is suitable for a variety of ciliary body non-magnetic foreign bodies with irritating symptoms. Contraindications Non-magnetic foreign bodies with ciliary body with unclear diagnosis, inaccurate positioning, and no irritation, are not suitable for surgery. Preoperative preparation Ultrasound or CT examination is performed to clarify the size and shape of foreign objects and to locate foreign bodies. If necessary, add a boneless camera and checkered position check on the operating table. The distance between the foreign body position and the expected surgical incision should not exceed 0.5 mm. Surgical procedure 1. Use the opener to separate the upper and lower eyelids and pull the sutures of the upper and lower rectus muscles. The traction line is moved according to the position of the foreign object, and the anterior segment of the eye is fully exposed. 2. Incision of the bulbar conjunctiva at the limbus, about 1 quadrant, separating the conjunctiva and exposing the sclera of the ciliary body. After the electric body is placed in the foreign body (ciliary body area), a rectangular lamellar sclera is cut (cut in three sides, one side is reserved), and when the deep sclera is cut into the deep layer 3/4, the sclera on both sides is cut. Stitch the 9-0 nylon thread or 5-0 silk thread and lift the middle thread string as a preset stitch. 3. Another method is to make a trephus in the ciliary body area, cut through the 4/5 of the annular sclera, and leave 1/5 of the sclera without cutting around for uncovering and closing. 4. In the electroosmotic part of the lamellar scleral area, the remaining sclera should be cut vertically, and the length should be 2 mm more than the estimated diameter of the foreign body. For the irregular foreign body, it should be changed into a "T" shape. In the scleral incision area, adrenaline and thrombin (fibrin) were taken. After 1 minute, according to the location of the foreign body, the ciliary body was cut with a micro-shaped electrocoagulation knife, and the micro-duck pliers were used to clamp the foreign body and slowly pulled out. . 5. Tightening the scleral suture and ligation, suturing the bulbar conjunctiva.
