On May 25, the Affiliated Hospital of Sichuan Panzhihua University successfully carried out the Foldable Artificial Vitreous Balloon (FCVB) operation again. The operation was performed by Professor Ran Qi and Professor Wu Chengfu of the hospital, and successfully implanted three silicone oil eye patients. Vitreous balloon.

Condition introduction

01. Gender: Male Age: 16 years old
Chief Complaint: Half-eye glass-filled silicone oil filling left eye
Half a year ago, he was suffering from “proliferative vitreoretinopathy of the left eye with retinal detachment, foraminal retinal detachment of the left eye, root iris dissociation of the left eye, conjunctival injury of the left eye, laceration of the left eyelid, and hemorrhage of the left eye. Affiliated Hospital of Panzhihua University underwent “left eye posterior approach vitrectomy with replacement injection, anterior chamber puncture, vitreous silicone oil filling, vitreous gas-liquid exchange, retinal reposition, posterior lens capsule resection, vitreous cavity rehydration injection , Retinal Reduction.” He was instructed to perform regular re-examinations after the operation and to perform silicone oil removal according to the recovery of the retina after surgery. He returned to the hospital for treatment in the near future.
02. Gender: Male Age: 35 years old
Chief complaint: vision loss after vitrectomy for left eye for 1 year
He had performed several operations due to trauma. One year ago, he was hospitalized for “endophthalmitis in the left eye, corneal laceration in the left eye, optic nerve damage in the left eye, vitreous hemorrhage in the left eye, and traumatic cataract in the left eye.” “Vitreous cavity injection” and “left-limiting intravitreal injection + anterior chamber puncture and drainage” were performed 3 times; the patient was discharged after stable operation. After regular review. He came to the hospital 11 months ago for re-examination. He was admitted to the hospital again because of “hyperplastic vitreous retinal abdomen with retinal detachment, left-sided vitreous hemorrhage, left-eye retinal detachment, and traumatic cataract in the left eye.” Left-eye posterior vitrectomy with replacement injection + vitreous silicone oil filling + anterior retinal membrane resection + optic canal hole cryosurgery + cataract ultrasound aspiration, vitreous cavity gas injection + retinal reduction” and “left “Anterior capsule laser” treatment, the patient was discharged steadily. About 6 months ago, he came to the hospital again to do “left eye vitreous silicone oil removal + anterior chamber puncture + anterior chamber irrigation”. After 11 days of postoperative follow-up in the outpatient clinic, “left eye retinal detachment” appeared again, and he was hospitalized again, and “left eye posterior approach vitrectomy with replacement injection + ciliary body drainage surgery retinal hole cryosurgery + sclera plus Pressure with filling + vitreous silicone oil filling, air wave exchange + retina reduction + anterior chamber puncture.” After the operation, he was asked to do regular re-examination. He re-examined half a month ago and again found retinal detachment in the left eye. Further surgical treatment was recommended.
03. Gender: Male Age: 62 years old
Chief complaint: vision loss after vitrectomy for left eye for 1 year
He was admitted to the hospital because of a “rupture of the right eyeball” 7 months ago and underwent “right eye sclera laceration suture, skin suture, full-thickness eye and face reconstruction with eyelid margin, full-thickness eyelid laceration repair, and embedding of foreign bodies in the eye and face Conjunctival sac plasty, conjunctival laceration repair, vitreous drug injection, artificial lacrimal implantation, lacrimal canal anastomosis, endoscopic sinus opening surgery on the right side, posterior approach vitrectomy with replacement Injection, cataract phacoemulsification aspiration, retinal detachment laser treatment, retinal detachment electrocoagulation, retinal retinal resection, vitreous drug injection, vitreous silicone oil filling, vitreous cavity exploration, vitreous cavity heavy water injection, retinal reduction Surgery, vitreous gas-liquid exchange, retinal reposition, anterior chamber angioplasty, anterior chamber puncture, and recanalization of the perforated iris”. The patients are reviewed regularly after the procedure and the condition is stable. In order to further treatment, he recently came to the hospital again, and the outpatient was admitted with “OD after retinal detachment”. Since he became ill, he has suffered heavy burnout and his appetite is fair.
Professor Ran Qi and Professor Wu Chengfu diagnosed and treated these three patients. They were all retinal detachment due to eye trauma or other reasons. They had been injected with silicone oil for treatment, but after a period of time, they found that the retina was detached again. For further treatment, Professor Ran and Professor Wu decided to carry out the Foldable Artificial Vitreous Balloon (FCVB) operation for them, and invited the developer of the product, Professor Gao Qianying, to assist.

△Durning Surgery

According to the latest postoperative examination, the postoperative results of the three patients were very good, all achieved the expected results, and were discharged from the hospital on June 1. In addition, it is expected that on the 10th of this month, 3 more silicone oil eye patients will be admitted to the hospital for FCVB surgery. In fact, the affiliated hospital of Panzhihua University has already started FCVB surgery in 2019, successfully treating many patients with severe eye trauma and silicone oil eyes. Now that the epidemic has weakened, the hospital has carried out FCVB surgery again. The vast majority of patients with severe eye trauma and silicone oil in the southwest can go to the hospital for treatment.


· The product consists of a balloon, a drainage tube and a drainage valve. The balloon can accurately simulate the vitreous structure of the human eye, and the medium (silicone oil) is injected through the drainage valve to restore the function of the vitreous to support the retina and the eyeball, which can prevent the silicone oil from shifting and emulsifying, and can remain in the eye for a long time.
