How much do you know about “fundus hemorrhage” – Understanding retinal vein occlusion

  Are you troubled by “bleeding from the fundus”? “What are the causes of fundus bleeding? And how to treat it? I will answer all of your questions below!  1.What is “fundus hemorrhage”?  Clinically, many fundus lesions will appear as “fundus hemorrhage”, such as retinal vein obstruction, age-related macular degeneration, diabetic retinopathy, high myopia fundus hemorrhage, etc., but usually what we call “fundus hemorrhage” mainly refers to the fundus of the eye. The main reason for this is the blockage of blood vessels in the eye. There are many causes, including thick blood, high blood lipids, high blood sugar, high blood pressure, arteriosclerosis, and inflammation of veins. The incidence is higher in patients with hypertension and atherosclerosis. Beijing Hospital Ophthalmology Yu Xiaobing 2.Does obstruction of the veins in the fundus of the eye necessarily have a brain or heart attack?  The veins of the eye are very fine, and a small blood clot may cause a blockage of the blood vessel. But the blood vessels of brain and heart are large blood vessels, which are thicker than the blood vessels of eyes, so small thrombus is not easy to cause cerebral thrombosis or myocardial infarction. So most of the patients with retinal vein obstruction will not have brain infarction or heart infarction at the same time, but it suggests the existence of small thrombus, so we should pay attention to check the cause and treat it actively.  3.What are the manifestations of “fundus hemorrhage”?  When the scope of retinal vein obstruction is small, the patient may not have obvious conscious symptoms or only show mild vision loss, so it is easy to be ignored. When the lesion involves the macula, macular edema may occur, leading to severe vision loss, visual distortion and visual field defects. With the prolongation of obstruction, neovascular glaucoma may occur, when the vision loss is obviously accompanied by eye pain and headache.  4.What tests are needed to detect fundus hemorrhage?  Systemic examination is mainly blood pressure, blood lipid, blood sugar, blood viscosity and carotid ultrasound, etc. Young people should check the immunology department; Ophthalmology specialist examination: visual acuity, intraocular pressure, slit lamp ophthalmoscopy, OCT, fundus fluorescence angiography, etc.  5.What are the treatments for fundus hemorrhage?  The treatment methods for retinal vein obstruction are as follows: medication, laser treatment, intraocular injection treatment. At present, intraocular injection combined with laser treatment is supplemented by drug treatment.  Intraocular injection mainly treats patients with macular edema, and most of the macular edema subsides and vision improves after treatment. Intraocular injections include VEGF antibody razumab, glucocorticoids such as tretinoin, long-acting dexamethasone extended-release agent, etc. Fundus laser treatment is mainly to delay the development of the disease, prevent the production of neovascularization or eliminate neovascularization to avoid more serious vision loss. Patients feel swollen and painful during traditional laser treatment. The multi-point scanning laser used at Beijing Hospital this year has been well received by patients, and the painlessness and rapidity are the biggest advantages of the PASCAL laser.  Medication is mainly used to help the absorption of bleeding in the fundus, and herbal medicines can be used to promote blood circulation and remove blood stasis. Different types of patients choose different treatment options, and the clinician should be consulted for details.  6.What is the treatment effect of “fundus hemorrhage”?  The prognosis of retinal vein obstruction varies according to the severity of the disease and the frequency of recurrent episodes, and most of the hemorrhages are gradually absorbed within 6-12 months. Overall, the longer the time to onset and the later the treatment, the worse the outcome. With the application of new drugs such as razumab and long-acting hormones, early treatment is more effective. Therefore, early detection, early diagnosis and early treatment are recommended.
