Ciliary body mass excision

The front of the ciliary body is connected to the iris and the posterior to the choroid. The three are closely related to the tissue structure. Therefore, the ciliary body mass sometimes extends to the iris or choroid, and the iris and choroidal mass may also extend to the ciliary body. The position of the ciliary body is relatively concealed, and its mass is not easy to be detected at an early stage. It is often found in the case of a patient with clinical symptoms, and the ciliary body compression mirror can be found in the case of fully dilated pupil. Ciliary body tumors are more common with melanoma, followed by ciliary body myeloma, malignant or benign ciliary body epithelioma and ciliary body cysts or ciliary epithelial cysts. Ciliary astrocytoma, ciliary retinoic glioma, iridocyclin glioma, ciliary schwannomas, ciliary leiomyomas, ciliary body vascular epithelioma and plasmacytoma It is rare. Malignant melanoma is more common in malignant melanoma of the ciliary body, but both Hodes et al. and Reese believe that the malignant melanoma of the iris and ciliary body is a low-grade malignant tumor, usually does not metastasize, and advocates that there are complications and decreased vision. Only consider surgery. Treatment of diseases: ciliary body melanoma Indication Ciliary body mass resection is applicable to: 1. A benign mass of the ciliary body or the iris ciliary body. 2. There are no other systemic malignant tumors in the body. 3. The surgical eye still has useful vision. 4. The patient refused to do eyeball removal. Contraindications 1. Ciliary body malignant mass, which grows faster and has spread to the outside of the eye. 2. Systemic malignant tumors metastasize to the ciliary body, mostly in the advanced stage of malignant tumors, most patients die of primary malignant tumors within a few months. Surgical procedure This method is used in the Stallard method for tumors less than 2 time limits. (1) Place the opener and make the upper and lower rectus muscle traction sutures. (2) Conjunctival incision was made along the limbus at the site of the tumor. The two ends of the incision exceeded the mass of the tumor by about 3 to 4 mm. The two ends were radially cut into the conjunctiva and the Tenon's capsule was about 10 mm. After separation, the angled limb and sclera were exposed. (3) If the expected radial incision of the sclera does not affect the rectus muscle, do not need to cut the rectus muscle to avoid unnecessary damage. (4) 2/3 thick scleral incision along the angle of the corresponding tumor site, 2 to 3 mm beyond the mass at both ends, and a radial 2/3 thick scleral incision to the equator of the eyeball, and the scleral flap is separated, and then Make 3 preset stitches. (5) In the scleral flap, make a circle of heat transfer around the mass. (6) Cut through the angle of the limbal incision, close the tumor to remove the iris that adheres to it, and cut off the scleral lamellar layer and ciliary body along the electroosmotic area around the tumor. (7) The suture angle of the sulcus angle was preset, and the suture was sutured with 2 needles and the scleral incision was sutured with 4 needles. (8) suture the conjunctival incision.
