1.When is biosurgery necessary for patients with glycogen reticulation? What is the difference between the indications and laser treatment?
Diabetic patients with vitreous hemorrhage not absorbed for 1 month, or retinal proliferation and traction in the fundus, or even retinal detachment, pre-macular hemorrhage not absorbed and persistent macular edema not subsiding, need to consider vitrectomy. Yu Xiaobing, Ophthalmology Department, Beijing Hospital
Indications for laser: early laser treatment should be done when the retina is neovascularized or at risk of neovascularization before there is an obvious vitreous accumulation of blood in the fundus.
2.Is it possible to improve vision after vitrectomy? Will the symptoms of vitreous congestion still occur?
Whether the vision can be improved after vitrectomy depends on the severity of the fundus lesion, especially whether the optic nerve and macula have lesions.
After the surgery, if the blood sugar and blood pressure control is unstable, high and low, or high blood sugar and blood pressure, or forceful coughing and constipation, etc. may cause the possibility of bleeding again.
3.Is it necessary to inject silicone oil or gas for biosurgery? Is silicone oil or gas better? Is it necessary to remove the silicone oil later? How long will it take to remove? How long does it take for the gas to be absorbed?
If the fundus lesion is not too serious, many patients do not need to inject gas or silicone oil, and the recovery after surgery is fast and good.
If the fundus is severe and silicone oil or gas is injected during the surgery, the head will need to be placed in a low position after the surgery and the gas will usually take 1-2 weeks to absorb. After that, there is no need to sleep on your back. However, if silicone oil is injected, the silicone oil needs to be removed about 3 months after surgery and another surgery will be done. However, whether to inject silicone oil or gas is determined by the severity of the fundus lesion. There are many people whose vision is well restored after the gas is absorbed and the silicone oil is removed.
4.Does biosurgery need to be performed at the same time as other surgeries such as cataract? Under what circumstances do IOLs need to be implanted?
Beijing Hospital performs the most advanced 25G minimally invasive biosurgery, which can perform cataract ultrasound emulsification and IOL implantation at the same time. The surgery is performed by the same surgeon and is now a routine procedure.
The need for IOL implantation is determined by the surgeon depending on the condition of the fundus. If silicone oil is injected into the eye during the surgery, usually the lens will not be implanted during this surgery and the IOL can be implanted when the oil is removed.
5.If there are other eye diseases that need to be treated after biosurgery, is it possible to have laser? Will silicone oil and gas affect the laser treatment?
If you need laser treatment after biosurgery, it is possible to have laser treatment for the fundus of the eye.
Silicone oil does not usually interfere with laser treatment. However, the gas will block the fundus and affect the laser, usually wait for the gas to be absorbed before laser treatment.
6.What kind of medicine can be taken after biosurgery to prevent the fundus from bleeding again? Is it feasible for patients to take “Sanchi” and “Volitene” after bleeding?
There is no medicine to prevent bleeding again after biosurgery, and it is important to control blood sugar and blood pressure.
In case of bleeding again, it is usually recommended to take “Yunnan Baiyao” orally within a week after bleeding, and “Volitin” (lecithin complex iodine) orally within a week after bleeding.
7.Is it normal for my eyes to turn red and my vision to decrease after surgery? Do I need to go to the hospital for examination?
In the past, it was normal to have red eyes after biosurgery, but nowadays, it is rare to have red eyes after minimally invasive surgery. If there is a loss of vision, it is still necessary to go to the hospital for examination.
8.Is it possible to have neovascular glaucoma after vitreoretinal surgery? How to detect it early?
Neovascular glaucoma can occur with diabetes whether or not vitreous surgery is performed. Usually vitreous surgery will reduce the risk of neovascular glaucoma.
How patients can detect neovascular glaucoma early is by paying attention to their eye pressure, which is likely if it is elevated. Doctors can detect it early through careful examination
9.What preparations are needed before surgery? What are the precautions after surgery?
Before vitrectomy, you need to control blood sugar and blood pressure, and stop using aspirin, vitreous humor and other bleeding drugs.
After surgery, you still need to control blood sugar and blood pressure, avoid strenuous exercise, coughing, constipation and other force.
