This symptom suddenly appears in the eyes, which may be caused by high blood pressure or diabetes

The fundus is the part where arteries, veins and capillaries can be directly observed with the naked eye. These blood vessels can reflect the state of blood circulation and health of the human body, so many systemic diseases can be reflected through the fundus. The main harm of fundus disease to the human body is the decline of visual function, and severe lesions may cause blindness. Many patients do not have enough knowledge about fundus disease and do not understand the harmfulness of the disease, thus delaying treatment.

Common fundus diseases

Macular degeneration

The macula is a small area in the center of the eye, and it plays a very important role in the entire eye structure. It is often compared to the "heart of the eye" because it is the place where vision is very sharp.

Once the macula is diseased, vision will change significantly, such as abnormal color vision, blurred central vision, metamorphosis, distortion, dark colors , etc. Once macular degeneration reaches the point where central vision decreases, it is almost impossible to reverse it. Once vision decreases after the age of 50, you need to be alert to age-related macular degeneration.

Diabetic retinopathy

Diabetic retinopathy, also known as "diabetic retinopathy", is an eye disease that can cause vision loss or even blindness. It has a high incidence rate and is very common among diabetics. Many diabetic patients with eye lesions do not show obvious symptoms in the early stages, such as no redness, pain, itching, or bleeding, so it is easy to be ignored. It is recommended that diabetic patients must regularly check the health of the fundus.

Central retinal artery occlusion

Retinal artery occlusion is also known as "eye stroke". Risk factors for stroke include high blood pressure, high blood lipids, cardiovascular and cerebrovascular diseases! "Eye stroke" is sudden and painless . If you experience blurred vision or even sudden loss of vision in one eye, like suddenly turning off a light, you must see an ophthalmologist as soon as possible. Don't miss the golden time to rescue patients with central retinal artery occlusion, otherwise the retinal nerve tissue will often suffer irreversible damage.

Retinal detachment

Among fundus diseases, there is a common and very complicated disease called "rhegmatogenous retinal detachment". As the disease progresses, the scope of retinal detachment gradually expands. Once it affects the macular area, vision deteriorates severely, and may even cause complete blindness and eyeball atrophy.

Mesothelioma

Central serous chorioretinopathy is a common posterior segment disease. Its full name is central serous chorioretinopathy. It is a common macular disease caused by damage to the retinal pigment epithelium. Unlike other fundus diseases, central serous chorioretinopathy is more likely to affect young and middle-aged men . Patients have symptoms such as blurred vision, central vision loss, fixation shadows, visual distortion, and discoloration .

Tianjin University Aier Eye Hospital kindly reminds that whether you are a high-risk group with diabetes, hypertension, hyperlipidemia, cardiovascular and cerebrovascular diseases, or high myopia, or an ordinary person without these problems, you should pay attention to healthy diet . Smoking and high-fat, high-cholesterol diets are closely related to age-related macular degeneration, retinal vascular occlusion and other fundus diseases. Wear appropriate sunshades when doing outdoor activities in strong sunlight. At the same time, people with the three highs should also regularly check their fundus health .
