What causes eye bleeding? These three types of people should pay attention!

"Doctor, please help me, am I having retinal bleeding?

What medicine would be better?"

The patient has small flakes of bleeding in the white of the inner corner of the eye

Red, very eye-catching

However, is this really the retinal hemorrhage that the patient said?

Ocular surface hemorrhage and retinal hemorrhage

Generally, the flake-like hemorrhages found in the white of the eye that can be seen by the naked eye are usually ocular surface hemorrhages. It is also called "subconjunctival hemorrhage", which is mainly caused by the rupture of the conjunctival blood vessels on the surface of the eyeball. Most of them are caused by vascular factors such as blood pressure fluctuations, rubbing the eyes hard, mechanical factors or local eye inflammation, and generally disappear on their own in a few days or one or two weeks.

Although ocular surface hemorrhage looks scary, in fact, fundus hemorrhage is more harmful than ocular surface hemorrhage. The fundus is the internal structure of the eye that cannot be observed with the naked eye. Therefore, unless the use of ophthalmic equipment, fundus hemorrhage has no symptoms in the early stage and the eye does not look abnormal, so it is easy to be ignored by patients and is a hidden killer of vision.

When the fundus hemorrhage gradually worsens, black shadows will slowly appear in front of the eyes, affecting vision. If the fundus hemorrhage is located in the macular area or optic nerve area in the center of the retina, it will cause serious loss of central vision or visual field.

Who is at higher risk of retinal hemorrhage?

1. Patients with diabetes and hypertension. Due to long-term high blood sugar, diabetic patients will damage blood vessels throughout the body, and the retinal blood vessels of the eyes will become relatively fragile, resulting in fundus hemorrhage. Hypertension patients may cause damage to the retinal blood vessels of the fundus, leading to fundus hemorrhage.

2. Patients with wet age-related macular degeneration. If new blood vessels appear in the retinal macula of the fundus, the proliferating new blood vessels are relatively fragile and easily lead to rupture and bleeding.

3. Severe myopia. Severe myopia causes the retina at the fundus of the eyeball to become thinner due to the elongation of the eye axis, making retinal detachment and hemorrhage more likely to occur.

Li Zhaohui, deputy director of the Department of Fundus Diseases at Wuhan University Aier Eye Hospital, reminded the above three groups of people to go to the hospital for regular eye examinations. The risk of fundus hemorrhage is much greater than that of ocular surface hemorrhage. If eye abnormalities occur, it is recommended to check and see a doctor as soon as possible for more appropriate treatment.
