People who are middle-aged, five blind blind diseases can not help

- May 09, 2019-

Most people now think that when they are older, they look blurry and distorted. They always feel black spots in front of them... It is a normal physiological aging phenomenon. In fact, these seemingly normal symptoms are likely to be very likely. Sexuality leads to blindness. For example, friends with chronic diseases such as hypertension, diabetes, and arteriosclerosis must pay special attention. Once these eye changes, they must not be ignored!


The cause of cataract is not fully understood, but its occurrence has a lot to do with age. With the increase of age, the incidence of senile cataracts is on the rise, accounting for more than 80% of all cataract patients.

Cataract is the world's first blind eye disease, about 48%. Cataract visual perception: ghosting, blurring, abnormal color


Glaucoma is the second blinding cause and the first irreversible blindness factor in the world.

Acute glaucoma attacks can cause eye swelling, eye pain, rainbow vision (there will be a rainbow-like aperture when looking at the light), migraine, nausea, vomiting and other symptoms.

Chronic glaucoma symptoms are not obvious, especially in early patients, there is no feeling of vision, visual acuity, visual field defect, eye swelling, headache and other symptoms in the middle and late stages.

Diabetic retinopathy

 It is a serious complication of diabetes. The number of diabetic patients in China has exceeded 100 million. The complications of diabetes are extremely harmful to the health of the body, and the eyes are the most easily overlooked. In general, diabetic patients over the age of 40, especially those with diabetes for more than 5 years, will slowly develop diabetic retinopathy.

Macular degeneration

This is a degenerative fundus disease. It is easy to cause serious central vision loss and loss, and it is also one of the main causes of blindness in middle-aged and elderly people. The macular area is the most sensitive area of human eye vision. If it is sick, the visual function will be seriously damaged. As the age increases, some of the middle-aged and elderly people have degeneration in the macular area, causing vision loss, seeing things deformed, black shadows, etc., and serious conditions can lead to blindness.

Fundus hemorrhage

Fundus hemorrhage is not an independent eye disease, but a feature shared by many eye diseases and certain systemic diseases. The causes of fundus hemorrhage are complex, easy to recurrent, seriously affecting vision, can cause many serious complications, such as macular degeneration, glaucoma, and retinal detachment, etc., if not timely and effective treatment, often lead to blindness.
