The use of laser treatment for diabetic fundus hemorrhage can be accompanied by certain complications. The main purpose of fundus laser therapy is to photocoagulate and seal the hemorrhage on the retinal surface using a high-energy laser. However, laser treatment is inherently destructive and can destroy adjacent fundus tissue while photocoagulating the lesion. Considering that diabetic patients are suffering from ruptured hemorrhage caused by increased blood glucose resulting in impaired microcirculation in the fundus, abnormal retinal vascular endothelial cells, and increased vascular fragility. Complications in diabetic patients in this state may be more pronounced.
Common complications of laser treatment of fundus hemorrhage include: 1. Pain: Some patients may experience prolonged and severe pain or even headache after the procedure. You can take oral painkillers such as ibuprofen half an hour before the laser. 2. Re-bleeding: Especially in some patients with diabetes combined with hypertension, re-bleeding can occur if blood pressure and blood sugar are not well controlled. Therefore, after laser surgery, blood pressure and blood glucose should be closely observed, and blood pressure and blood glucose should be controlled by medication. 3, visual field loss, this symptom is mainly due to retinal damage at the laser site, and there will be no vision at the damaged retinal area when looking at something. 4, vision loss or even loss: after the closure of photocoagulation vessels, if the scar scab at the cauterized area falls off, it will trigger a larger area of bleeding, and blood accumulation in the vitreous will lead to vision The result is a decrease in vision or even blindness.
