Panretinal combined with cyclocondensation

Reduced aqueous humor secretion surgery, also known as ciliary body destruction surgery, surgery is represented by ciliary body cryoablation, ciliary body diathermy, transscleral microwave ciliary body destruction surgery, etc., with different types of energy on the ciliary body Destruction reduces the formation of atrophy of the ciliary body and reduces the intraocular pressure. Because this kind of surgery has damage to the eyeball to a certain extent, the predictive effect of the operation is poor, too little to achieve the purpose, and too much causes the eyeball to shrink, so this type of surgery can only be used as the last resort for glaucoma surgery or other Surgery as an adjuvant therapy. In recent years, Nd:YAG laser or semiconductor diode laser through the sclera or through the pupil to destroy the ciliary body, especially the latter part of the ciliary body photocoagulation is relatively accurate, and achieved good clinical results. Reduced complications. The development of intraocular endoscopy combined with intraocular laser surgery in recent years will provide a better surgical method for patients with advanced glaucoma. Whole retinal combined with ciliary body condensation is mainly used for neovascular glaucoma. Whole retinal condensation can regress neovascularization of the retina and iris, reducing hypoxia in the retina to reduce neovascularization factors. The purpose of ciliary body freezing is to reduce the production of aqueous humor. Treatment of diseases: neovascular glaucoma Indication Whole retinal combined with ciliary body condensation is suitable for neovascular glaucoma caused by retinal vasculopathy. Contraindications Whole retinal photocoagulation cannot be performed due to the following conditions: 1. Corneal opacity, edema, blisters. 2. Cataracts. 3. The pupil cannot be enlarged. Preoperative preparation In order to prevent transient high intraocular pressure and uveal inflammatory response after surgery, corticosteroids and diclofenac sodium eye drops were applied topically for 3 days before operation. Oral indomethacin 50 mg was given 30 minutes before surgery. If the intraocular pressure is high, oral acetazolamide can be administered. 500mg, intravenous infusion of mannitol 250ml. In severe cases, 50 mg of meperidine was administered intramuscularly 30 min before surgery, and 25 mg of phenergan. Surgical procedure The sputum is opened, the bulbar conjunctiva is cut from the limbus 360°, and the bulbar conjunctiva is cut radially on the nose, underarm or supra, and under the nasal quadrant. The fascia is separated from the equator and the 4-straight muscle traction line is used. 2.5mm or 3mm diameter freezing head, each quadrant freezes 5 points in the first row with the equator, and then interlaces the front and the equator to the front and the equator in the first row, 4 to 5 points per row, freezing The time is 8 to 10 s after the condensation head is frosted and the sclera is white. If the fundus can be seen with the ophthalmoscope, the time when the retina begins to whiten under direct vision shall prevail. Ciliary body freezing and ciliary body cryotherapy.
