On May 10th, Dongguan Aier Eye Hospital successfully launched the first peribulbar pressure balloon (FCB) operation. This operation was performed by Professor Tang Shibo, the dean of the Aile School of Ophthalmology, Central South University and the dean of the Aile Eye Hospital Group The knife successfully cured a patient with rhegmatogenous retinal detachment.

The patient, Mr. Liu, is 57 years old and has undergone multiple surgeries due to retinal detachment. At the beginning of May, he came to Dongguan Aier Eye Hospital because of “decreased left eye vision with dark shadow in front of his eyes for 1 day”. He was found to have no congestion in both eyes and transparent cornea. The optic disc of the right eye is round, with clear borders and pale red. The temporal omentum can be closed, the peripheral laser pigmentation, the retina is flat, and there is no obvious bleeding or bleeding in the macular area. The optic disc of the left eye is round and the border is clear. At 1:30, a 1PD horseshoe-shaped hole was seen, and the retina was grayish-white uplifted from 11 to 2 o’clock, detached from the macula, and the laser spot pigmentation in the lower peripheral retinal degeneration area. Dean Tang Shibo diagnosed him as “foraminal retinal detachment in the left eye, after retinal reposition in the right eye, after retinal laser photocoagulation in both eyes, intraocular lens in both eyes, and refractive error in both eyes”, and decided to treat him with FCB and invited Professor Gao Qianying, a product developer, came to assist.

△Preoperative examination of retinal detachment

On the afternoon of the 10th, Dean Tang carried out extra-scleral silicone pressure on the left eye + vitreous puncture and gas injection + internal drainage for his symptomatic treatment such as infection prevention and anti-inflammatory. The external scleral silicone cushioning operation uses FCB, which has more advantages than traditional silicone. On the 14th, the left eye retinal laser photocoagulation was used to close the hole. After the operation, Mr. Liu also lamented that because of the rhegmatogenous retinal detachment, he performed several operations on his right eye. Each time he was frightened, and the operation process was very long and painful. This time, Dean Tang’s left eye surgery was quick and not as painful as before. Thank you very much for Dean Tang’s “good hands”. He removed the gauze after the operation without discomfort such as swelling and eye pain. His left eye was still clear and recovered well. On the fourth day after surgery, Mr. Liu was discharged from the hospital.

The FCB is implanted into the corresponding sclera surface through a conjunctival incision of approximately 4-5 mm, and physiological saline is injected through the drainage valve and drainage tube. After injecting normal saline, the FCB can support the pressure against the sclera and retina, close the hole with laser or condensation, and treat rhegmatogenous retinal detachment. Compared with traditional surgery for rhegmatogenous retinal detachment, FCB treatment has 5 advantages:
1. Simple operation, easy to grasp, more minimally invasive, free posture after operation, and less complications;
2. Adjustable, can be taken out and the retention time can be controlled;
3. It is not necessary to freeze during the operation, and laser treatment for net prolapse with mild proliferative lesions can also reduce the possibility of freezing aggravating proliferative lesions;
4. There is no pain during the operation, there is no need to stretch the muscle, the stimulation is small, and the whole body risk is less;
5. Good biocompatibility and meet the requirements of implants in human body.
FCB has brought new hope to the majority of patients with rhegmatogenous retinal detachment. A multi-center clinical research meeting was held in 2019. Among them, Dean Tang Shibo is the chief lead, Professor Hui Yannian is the chairman of the Reading Committee, Professor Jia Yading and Professor Li Tao are the Deputy Chairman of the Reading Committee. This year, 19 clinical trial units nationwide have successfully carried out more than 10 operations. Today, multi-center clinical research trials are still in progress. Patients with rhegmatogenous retinal detachment can consult the following clinical units▽
